In music, an ostinato [ostiˈnaːto] (derived from Italian: stubborn, compare English, from Latin: 'obstinate') is a motif or phrase that persistently repeats in the same musical voice, frequently in the same pitch. Well-known ostinato-based pieces include both classical compositions, such as Ravel's Boléro and the Carol of the Bells , and popular songs such as Donna Summer and Giorgio Moroder's "I Feel Love" (1977), Henry Mancini's theme from Peter Gunn (1959), and The Verve's "Bitter Sweet Symphony" (1997).
Both ostinatos and ostinati are accepted English plural forms, the latter reflecting the word's Italian etymology.
The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself.Strictly speaking, ostinati should have exact repetition, but in common usage, the term covers repetition with variation and development, such as the alteration of an ostinato line to fit changing harmonies or keys.
If the cadence may be regarded as the cradle of tonality, the ostinato patterns can be considered the playground in which it grew strong and self-confident.
Within the context of film music, Claudia Gorbman defines an ostinato as a repeated melodic or rhythmic figure that propels scenes that lack dynamic visual action.
Ostinati play an important part in improvised music (rock and jazz), in which they are often referred to as riffs or vamps. A "favorite technique of contemporary jazz writers", ostinati are often used in modal and Latin jazz and traditional African music including Gnawa music.
The term ostinato essentially has the same meaning as the medieval Latin word pes, the word ground as applied to classical music, and the word riff in contemporary popular music.
Ostinati are used in 20th-century music to stabilize groups of pitches, as in Stravinsky's The Rite of SpringIntroduction and Augurs of Spring.A famous type of ostinato, called the Rossini crescendo, owes its name to a crescendo that underlies a persistent musical pattern, which usually culminates in a solo vocal cadenza. This style was emulated by other bel canto composers, especially Vincenzo Bellini; and later by Wagner (in pure instrumental terms, discarding the closing vocal cadenza).
Applicable in homophonic and contrapuntal textures, they are "repetitive rhythmic-harmonic schemes", more familiar as accompanimental melodies, or purely rhythmic.The technique's appeal to composers from Debussy to avant-garde composers until at least the 1970s "... lies in part in the need for unity created by the virtual abandonment of functional chord progressions to shape phrases and define tonality". Similarly, in modal music, "... relentless, repetitive character help to establish and confirm the modal center". Their popularity may also be justified by their ease as well as range of use, though, "... ostinato must be employed judiciously, as its overuse can quickly lead to monotony".
Ostinato patterns have been present in European music from the Middle Ages onwards. In the famous English canon "Sumer Is Icumen In", the main vocal lines are underpinned by an ostinato pattern, known as a pes:
Later in the medieval era, Guillaume Dufay's 15th-century chanson Resvelons Nous features a similarly constructed ostinato pattern, but this time 5 bars long. Over this, the main melodic line moves freely, varying the phrase-lengths, while being "to some extent predetermined by the repeating pattern of the canon in the lower two voices."
Ground bass or basso ostinato (obstinate bass) is a type of variation form in which a bass line, or harmonic pattern (see Chaconne; also common in Elizabethan England as Grounde) is repeated as the basis of a piece underneath variations.Aaron Copland describes basso ostinato as "... the easiest to recognize" of the variation forms wherein, "... a long phrase—either an accompanimental figure or an actual melody—is repeated over and over again in the bass part, while the upper parts proceed normally [with variation]". However, he cautions, "it might more properly be termed a musical device than a musical form."
One striking ostinato instrumental piece of the late Renaissance period is "The Bells", a piece for virginals by William Byrd. Here the ostinato (or 'ground') consists of just two notes:
In Italy, during the seventeenth century, Claudio Monteverdi composed many pieces using ostinato patterns in his operas and sacred works. One of these was his 1650 version of "Laetatus sum", an imposing setting of Psalm 122 that pits a four-note "ostinato of unquenchable energy."against both voices and instruments:
Later in the same century, Henry Purcell became famous for his skilful deployment of ground bass patterns. His most famous ostinato is the descending chromatic ground bass that underpins the aria "When I am laid in earth" ("Dido's Lament") at the end of his opera Dido and Aeneas :
While the use of a descending chromatic scale to express pathos was fairly common at the end of the seventeenth century, Richard Taruskin points out that Purcell shows a fresh approach to this musical trope: "Altogether unconventional and characteristic, however, is the interpolation of an additional cadential measure into the stereotyped ground, increasing its length from a routine four to a haunting five bars, against which the vocal line, with its despondent refrain ("Remember me!"), is deployed with marked asymmetry. That, in addition to Purcell's distinctively dissonant, suspension-saturated harmony, enhanced by additional chromatic descents during the final ritornello and by many deceptive cadences, makes this little aria an unforgettably poignant embodiment of heartache."See also: Lament bass. However, this is not the only ostinato pattern that Purcell uses in the opera. Dido's opening aria "Ah, Belinda" is a further demonstration of Purcell's technical mastery: the phrases of the vocal line do not always coincide with the four-bar ground:
"Purcell's compositions over a ground vary in their working out, and the repetition never becomes a restriction."Purcell's instrumental music also featured ground patterns. A particularly fine and complex example is his Fantasia upon a Ground for three violins and continuo:
The intervals in the above pattern are found in many works of the Baroque Period. Pachelbel's Canon also uses a similar sequence of notes in the bass part:
Two pieces by J.S.Bach are particularly striking for their use of an ostinato bass: the Crucifixus from his Mass in B minor and the Passacaglia in C minor for organ, which has a ground rich in melodic intervals:
The first variation that Bach builds over this ostinato consists of a gently syncopated motif in the upper voices:
This characteristic rhythmic pattern continues in the second variation, but with some engaging harmonic subtleties, especially in the second bar, where an unexpected chord creates a passing implication of a related key:
In common with other Passacaglias of the era, the ostinato is not simply confined to the bass, but rises to the uppermost part later in the piece:
A performance of the entire piece can be heard here.
Ostinatos feature in many works of the late 18th and early 19th centuries. Mozart uses an ostinato phrase throughout the big scene that ends Act 2 of the Marriage of Figaro, to convey a sense of suspense as the jealous Count Almaviva tries in vain to incriminate the Countess, his wife, and Figaro, his butler, for plotting behind his back. A famous type of ostinato, called the Rossini crescendo, owes its name to a crescendo that underlies a persistent musical pattern, which usually culminates in a solo vocal cadenza.
In the energetic Scherzo of Beethoven’s late C sharp minor Quartet, Op. 131, there is a harmonically static passage, with "the repetitiveness of a nursery rhyme"that consists of an ostinato shared between viola and cello supporting a melody in octaves in the first and second violins:
Beethoven reverses this relationship a few bars later with the melody in the viola and cello and the ostinato shared between the violins:
Both the first and third acts of Wagner's final opera Parsifal feature a passage accompanying a scene where a band of Knights solemnly processes from the depths of forest to the hall of the Grail. The "Transformation music" that supports this change of scene is dominated by the iterated tolling of four bells:
Brahms used ostinato patterns in both the finale of his Fourth Symphony and in the closing section of his Variations on a Theme by Haydn :
Debussy featured an ostinato pattern throughout his Piano Prelude "Des pas sur la neige". Here, the ostinato pattern stays in the middle register of the piano – it is never used as a bass. "Remark that the footfall ostinato remains nearly throughout on the same notes, at the same pitch level... this piece is an appeal to the basic loneliness of all human beings, oft-forgotten perhaps, but, like the ostinato, forming a basic undercurrent of our history."
Of all the major classical composers of the Twentieth Century, Stravinsky is possibly the one most associated with the practice of ostinato. In conversation with the composer, his friend and colleague Robert Craft remarked "Your music always has an element of repetition, of ostinato. What is the function of ostinato?" Stravinsky replied; "It is static – that is, anti-development; and sometimes we need a contradiction to development." Stravinsky was particularly skilled at using ostinatos to confound rather than confirm rhythmic expectations. In the first of his Three Pieces for String Quartet, Stravinsky sets up three repeated patterns, which overlap one another and never coincide. "Here a rigid pattern of (3+2+2/4) bars is laid over a strictly recurring twenty-three-beat tune (the bars being marked by a cello ostinato), so that their changing relationship is governed primarily by the pre-compositional scheme." "The rhythmical current running through the music is what binds together these curious mosaic-like pieces."
A subtler metrical conflict can be found in the final section of Stravinsky's Symphony of Psalms . The choir sing a melody in triple time, while the bass instruments in the orchestra play a 4-beat ostinato against this. "This is built up over an ostinato bass (harp, two pianos and timpani) moving in fourths like a pendulum."
Many instruments south of the Sahara Desert play ostinato melodies.[ clarification needed ] These include lamellophones such as the mbira, as well as xylophones like the balafon, the bikutsi, and the gyil. Ostinato figures are also played on string instruments such as the kora, gankoqui bell ensembles, and pitched drums ensembles. Often, African ostinatos contain offbeats or cross-beats, that contradict the metric structure. Other African ostinatos generate complete cross-rhythms by sounding both the main beats and cross-beats. In the following example, a gyil sounds the three-against-two cross-rhythm (hemiola). The left hand (lower notes) sounds the two main beats, while the right hand (upper notes) sounds the three cross-beats.
Popular dance bands in West Africa and the Congo region feature ostinato-playing guitars. The African guitar parts are drawn from a variety of sources, including the indigenous mbira, as well as foreign influences such as James Brown-type funk riffs. However, the foreign influences are interpreted through a distinctly African ostinato sensibility. African guitar styles began with Congolese bands doing Cuban "cover" songs. The Cuban guajeo had a both familiar and exotic quality to the African musicians. Gradually, various regional guitar styles emerged, as indigenous influences became increasingly dominant within these Africanized guajeos.
As Moore states, "One could say that I – IV – V – IV [chord progressions] is to African music what the 12-bar blues is to North American music." Such progressions seem superficially to follow the conventions of Western music theory. However, performers of African popular music do not perceive these progressions in the same way. Harmonic progressions which move from the tonic to the subdominant (as they are known in European music) have been used in Traditional sub-Saharan African harmony for hundreds of years. Their elaborations follow all the conventions of traditional African harmonic principles. Gehard Kubik concludes:
The harmonic cycle of C–F–G–F [I–IV–V–IV] prominent in Congo/Zaire popular music simply cannot be defined as a progression from tonic to subdominant to dominant and back to subdominant (on which it ends) because in the performer's appreciation they are of equal status, and not in any hierarchical order as in Western music—(Kubik 1999).
A guajeo is a typical Cuban ostinato melody, most often consisting of arpeggiated chords in syncopated patterns. The guajeo is a hybrid of the African and European ostinato. The guajeo was first played as accompaniment on the tres in the folkloric changüí and son.The term guajeo is often used to mean specific ostinato patterns played by a tres, piano, an instrument of the violin family, or saxophones. The guajeo is a fundamental component of modern-day salsa, and Latin jazz. The following example shows a basic guajeo pattern.
The guajeo is a seamless Afro-Euro ostinato hybrid, which has had a major influence upon jazz, R&B, rock 'n' roll and popular music in general. The Beatles' "I Feel Fine" guitar riff is guajeo-like.
In various popular music styles, riff refers to a brief, relaxed phrase repeated over changing melodies. It may serve as a refrain or melodic figure, often played by the rhythm section instruments or solo instruments that form the basis or accompaniment of a musical composition.Though they are most often found in rock music, heavy metal music, Latin, funk and jazz, classical music is also sometimes based on a simple riff, such as Ravel's Boléro. Riffs can be as simple as a tenor saxophone honking a simple, catchy rhythmic figure, or as complex as the riff-based variations in the head arrangements played by the Count Basie Orchestra.
David Brackett (1999) defines riffs as "short melodic phrases", while Richard Middleton (1999)defines them as "short rhythmic, melodic, or harmonic figures repeated to form a structural framework". Rikky Rooksby states: "A riff is a short, repeated, memorable musical phrase, often pitched low on the guitar, which focuses much of the energy and excitement of a rock song."
In jazz and R&B, riffs are often used as the starting point for longer compositions. The riff from Charlie Parker's bebop number "Now's the Time" (1945) re-emerged four years later as the R&B dance hit "The Hucklebuck". The verse of "The Hucklebuck"—another riff—was "borrowed" from the Artie Matthews composition "Weary Blues". Glenn Miller's "In the Mood" had an earlier life as Wingy Manone's "Tar Paper Stomp". All these songs use twelve bar blues riffs, and most of these riffs probably precede the examples given.
Neither of the terms 'riff' or 'lick' are used in classical music. Instead, individual musical phrases used as the basis of classical music pieces are called ostinatos or simply phrases. Contemporary jazz writers also use riff- or lick-like ostinatos in modal music. Latin jazz often uses guajeo-based riffs.
In music, a vamp is a repeating musical figure, section,or accompaniment used in blues, jazz, gospel, soul, and musical theater. Vamps are also found in rock, funk, reggae, R&B, pop, country, and post-sixties jazz. Vamps are usually harmonically sparse: A vamp may consist of a single chord or a sequence of chords played in a repeated rhythm. The term frequently appeared in the instruction 'Vamp till ready' on sheet music for popular songs in the 1930s and 1940s, indicating the accompanist should repeat the musical phrase until the vocalist was ready. Vamps are generally symmetrical, self-contained, and open to variation. The equivalent in classical music is an ostinato, in hip hop and electronic music the loop, and in rock music the riff.
The slang term vamp comes from the Middle English word vampe (sock), from Old French avanpie, equivalent to Modern French avant-pied, literally before-foot.
Many vamp-oriented songwriters begin the creative process by attempting to evoke a mood or feeling while riffing freely on an instrument or scat singing. Many well known artists primarily build songs with a vamp/riff/ostinato based approach—including John Lee Hooker ("Boogie Chillen", "House Rent Boogie"), Bo Diddley ("Hey Bo Diddley", "Who Do You Love?"), Jimmy Page ("Ramble On", "Bron Yr Aur"), Nine Inch Nails ("Closer"), and Beck ("Loser").
Classic examples of vamps in jazz include "A Night in Tunisia", "Take Five", "A Love Supreme", "Maiden Voyage", and "Cantaloupe Island".Rock examples include the long jam at the ends of "Loose Change" by Neil Young and Crazy Horse and "Sooner or Later" by King's X.
In jazz, fusion, and related genres, a background vamp provides a performer with a harmonic framework supporting improvisation. In Latin jazz guajeos fulfill the role of piano vamp. A vamp at the beginning of a jazz tune may act as a springboard to the main tune; a vamp at the end of a song is often called a tag.
"Take Five" begins with a repeated, syncopated figure in 5
4 time, which pianist Dave Brubeck plays throughout the song (except for Joe Morello's drum solo and a variation on the chords in the middle section).
The music from Miles Davis's modal period (c.1958–1963) was based on improvising songs with a small number of chords. The jazz standard "So What" uses a vamp in the two-note "Sooooo what?" figure, regularly played by the piano and the trumpet throughout. Jazz scholar Barry Kernfeld calls this music vamp music.[ full citation needed ]
Examples include the outros to George Benson's "Body Talk" and "Plum", and the solo changes to "Breezin'".The following songs are dominated by vamps: John Coltrane, Kenny Burrell, and Grant Green's versions of "My Favorite Things", Herbie Hancock's "Watermelon Man" and "Chameleon", Wes Montgomery's "Bumpin' on Sunset", and Larry Carlton's "Room 335".
The Afro-Cuban vamp style known as guajeo is used in the bebop/Latin jazz standard "A Night in Tunisia". Depending upon the musician, a repeating figure in "A Night in Tunisia" could be called an ostinato, guajeo, riff, or vamp. The Cuban-jazz hybrid spans the disciplines that encompass all these terms.
In gospel and soul music, the band often vamps on a simple ostinato groove at the end of a song, usually over a single chord. In soul music, the end of recorded songs often contains a display of vocal effects—such as rapid scales, arpeggios, and improvised passages. For recordings, sound engineers gradually fade out the vamp section at the end of a song, to transition to the next track on the album. Salsoul singers such as Loleatta Holloway have become notable for their vocal improvisations at the end of songs, and they are sampled and used in other songs. Andrae Crouch extended the use of vamps in gospel, introducing chain vamps (one vamp after the other, each successive vamp drawn from the first).
1970s-era funk music often takes a short one or two bar musical figure based on a single chord one would consider an introduction vamp in jazz or soul music, and then uses this vamp as the basis of the entire song ("Funky Drummer" by James Brown, for example). Jazz, blues, and rock are almost always based on chord progressions (a sequence of changing chords), and they use the changing harmony to build tension and sustain listener interest. Unlike these music genres, funk is based on the rhythmic groove of the percussion, rhythm section instruments, and a deep electric bass line, usually all over a single chord. "In funk, harmony is often second to the 'lock,' the linking of contrapuntal parts that are played on guitar, bass, and drums in the repeating vamp."
Examples include Stevie Wonder's vamp-based "Superstition"and Little Johnny Taylor's "Part Time Love", which features an extended improvisation over a two-chord vamp.
In musical theater, a vamp, or intro, is the few bars, one to eight, of music without lyrics that begin a printed copy of a song.The orchestra may repeat the vamp or other accompaniment during dialogue or stage business, as accompaniment for onstage transitions of indeterminate length. The score provides a one or two bar vamp figure, and indicates, "Vamp till cue", by the conductor. The vamp gives the onstage singers time to prepare for the song or the next verse, without requiring the music to pause. Once the vamp section is over, the music continues to the next section.
The vamp may be written by the composer of the song, a copyist employed by the publisher, or the arranger for the vocalist.The vamp serves three main purposes: it provides the key, establishes the tempo, and provides emotional context. The vamp may be as short as a bell tone, sting (a harmonized bell tone with stress on the starting note), or measures long. The rideout is the transitional music that begins on the downbeat of the last word of the song and is usually two to four bars long, though it may be as short as a sting or as long as a Roxy Rideout.

In Indian classical music, during Tabla or Pakhawaj solo performances and Kathak dance accompaniments, a conceptually similar melodic pattern known as the Lehara (sometimes spelled Lehra)or Nagma is played repeatedly throughout the performance. This melodic pattern is set to the number of beats in a rhythmic cycle (Tala or Taal) being performed and may be based on one or a blend of multiple Ragas.
The basic idea of the lehara is to provide a steady melodious framework and keep the time-cycle for rhythmic improvisations. It serves as an auditory workbench not only for the soloist but also for the audience to appreciate the ingenuity of the improvisations and thus the merits of the overall performance. In Indian Classical Music, the concept of 'sam' (pronounced as 'sum') carries paramount importance. The sam is the target unison beat (and almost always the first beat) of any rhythmic cycle. The second most important beat is the Khali, which is a complement of the sam. Besides these two prominent beats, there are other beats of emphasis in any given taal, which signify 'khand's (divisions) of the taal. E.g. 'Roopak' or 'Rupak' taal, a 7-beat rhythmic cycle, is divided 3–2–2, further implying that the 1st, 4th, and 6th beats are the prominent beats in that taal. Therefore, it is customary, but not essential, to align the lehara according to the divisions of the Taal. It is done with a view to emphasize those beats that mark the divisions of the Taal.
The lehara can be played on a variety of instruments, including the sarangi, harmonium, sitar, sarod, flute and others. The playing of the lehara is relatively free from the numerous rules and constraints of Raga Sangeet, which are upheld and honoured in the tradition of Indian Classical Music. The lehara may be interspersed with short and occasional improvisations built around the basic melody. It is also permissible to switch between two or more disparate melodies during the course of the performance. It is essential that the lehara be played with the highest precision in Laya (Tempo) and Swara control, which requires years of specialist training (Taalim) and practice (Riyaaz). It is considered a hallmark of excellence to play lehara alongside a recognised Tabla or Pakhawaj virtuoso as it is a difficult task to keep a steady pulse while the percussionist is improvising or playing difficult compositions in counterpoint. While there may be scores of individually talented instrumentalists, there are very few who are capable of playing the lehra for a Tabla / Pakhawaj solo performance.
Funk is a music genre that originated in African American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of soul, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions and focuses on a strong rhythmic groove of a bassline played by an electric bassist and a drum part played by a drummer, often at slower tempos than other popular music. Like much of African-inspired music, funk typically consists of a complex groove with rhythm instruments playing interlocking grooves that create a "hypnotic" and "danceable" feel. Funk uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths and thirteenths.
In music performances, rhythm guitar is a technique and role that performs a combination of two functions: to provide all or part of the rhythmic pulse in conjunction with other instruments from the rhythm section ; and to provide all or part of the harmony, i.e. the chords from a song's chord progression, where a chord is a group of notes played together. Therefore, the basic technique of rhythm guitar is to hold down a series of chords with the fretting hand while strumming or fingerpicking rhythmically with the other hand. More developed rhythm techniques include arpeggios, damping, riffs, chord solos, and complex strums.
Bebop or bop is a style of jazz developed in the early to mid-1940s in the United States, which features compositions characterized by a fast tempo, complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and occasional references to the melody.
Polyrhythm is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic layers may be the basis of an entire piece of music (cross-rhythm), or a momentary section. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm. Concurrently in this context means within the same rhythmic cycle. The underlying pulse, whether explicit or implicit can be considered one of the concurrent rhythms. For example, the son clave is poly-rhythmic because its 3 section suggests a different meter from the pulse of the entire pattern.
A riff is a repeated chord progression or refrain in music ; it is a pattern, or melody, often played by the rhythm section instruments or solo instrument, that forms the basis or accompaniment of a musical composition. Though riffs are most often found in rock music, heavy metal music, Latin, funk and jazz, classical music is also sometimes based on a riff, such as Ravel's Boléro. Riffs can be as simple as a tenor saxophone honking a simple, catchy rhythmic figure, or as complex as the riff-based variations in the head arrangements played by the Count Basie Orchestra.
Latin jazz is a genre of jazz with Latin American rhythms. The two main categories are Afro-Cuban jazz, rhythmically based on Cuban popular dance music, with a rhythm section employing ostinato patterns or a clave, and Afro-Brazilian jazz, which includes samba and bossa nova.
In music, groove is the sense of an effect ("feel") of changing pattern in a propulsive rhythm or sense of "swing". In jazz, it can be felt as a quality of persistently repeated rhythmic units, created by the interaction of the music played by a band's rhythm section. Groove is a significant feature of popular music, and can be found in many genres, including salsa, rock, soul, funk, and fusion.
Son montuno is a subgenre of son cubano developed by Arsenio Rodríguez in the 1940s. Although son montuno had previously referred to the sones played in the mountains of eastern Cuba, Arsenio repurposed the term to denote a highly sophisticated approach to the genre in which the montuno section contained complex horn arrangements. He also incorporated piano solos and often subverted the structure of songs by starting with the montuno in a cyclic fashion. For his approach, Arsenio had to expand the existing septeto ensemble into the conjunto format which became the norm in the 1940s alongside big bands. Arsenio's developments eventually served as the template for the development of genres such as salsa, songo and timba.
Arsenio Rodríguez was a Cuban musician, composer and bandleader. He played the tres, as well as the tumbadora, and he specialized in son, rumba and other Afro-Cuban music styles. In the 1940s and 1950s Rodríguez established the conjunto format and contributed to the development the son montuno, the basic template of modern-day salsa. He claimed to be the true creator of the mambo and was an important as well as a prolific composer who wrote nearly two hundred songs.
A bassline is the term used in many styles of music, such as jazz, blues, funk, dub and electronic, traditional music, or classical music for the low-pitched instrumental part or line played by a rhythm section instrument such as the electric bass, double bass, cello, tuba or keyboard.
Accompaniment is the musical part which provides the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece.
In popular music genres such as country, blues, jazz or rock music, a lick is "a stock pattern or phrase" consisting of a short series of notes used in solos and melodic lines and accompaniment. Licks in rock and roll are often used through a formula, and variations technique in which variants of simple, stock ideas are blended and developed during the solo.
Afro-Cuban jazz is the earliest form of Latin jazz. It mixes Afro-Cuban clave-based rhythms with jazz harmonies and techniques of improvisation. Afro-Cuban jazz emerged in the early 1940s with the Cuban musicians Mario Bauzá and Frank Grillo "Machito" in the band Machito and his Afro-Cubans in New York City. In 1947, the collaborations of bebop trumpeter Dizzy Gillespie and percussionist Chano Pozo brought Afro-Cuban rhythms and instruments, such as the tumbadora and the bongo, into the East Coast jazz scene. Early combinations of jazz with Cuban music, such as "Manteca" and "Mangó Mangüé", were commonly referred to as "Cubop" for Cuban bebop.
Jazz piano is a collective term for the techniques pianists use when playing jazz. The piano has been an integral part of the jazz idiom since its inception, in both solo and ensemble settings. Its role is multifaceted due largely to the instrument's combined melodic and harmonic capabilities. For this reason it is an important tool of jazz musicians and composers for teaching and learning jazz theory and set arrangement, regardless of their main instrument.
In popular music, a fill is a short musical passage, riff, or rhythmic sound which helps to sustain the listener's attention during a break between the phrases of a melody. "The terms riff and fill are sometimes used interchangeably by musicians, but [while] the term riff usually refers to an exact musical phrase repeated throughout a song", a fill is an improvised phrase played during a section where nothing else is happening in the music. While riffs are repeated, fills tend to be varied over the course of a song. For example, a drummer may fill in the end of one phrase with a sixteenth note hi-hat pattern, and then fill in the end of the next phrase with a snare drum figure.
A chord chart is a form of musical notation that describes the basic harmonic and rhythmic information for a song or tune. It is the most common form of notation used by professional session musicians playing jazz or popular music. It is intended primarily for a rhythm section. In these genres the musicians are expected to be able to improvise the individual notes used for the chords and the appropriate ornamentation, counter melody or bassline.
Jazz improvisation is the spontaneous invention of melodic solo lines or accompaniment parts in a performance of jazz music. It is one of the defining elements of jazz. Improvisation is composing on the spot, when a singer or instrumentalist invents melodies and lines over a chord progression played by rhythm section instruments and accompanied by drums. Although blues, rock, and other genres use improvisation, it is done over relatively simple chord progressions which often remain in one key.
Excursions, Op. 20, is the first published solo piano piece by Samuel Barber. Barber himself explains:
These are ‘Excursions’ in small classical forms into regional American idioms. Their rhythmic characteristics, as well as their source in folk material and their scoring, reminiscent of local instruments are easily recognized.
A guajeo is a typical Cuban ostinato melody, most often consisting of arpeggiated chords in syncopated patterns. Some musicians only use the term guajeo for ostinato patterns played specifically by a tres, piano, an instrument of the violin family, or saxophones. Piano guajeos are one of the most recognizable elements of modern-day salsa. Piano guajeos are also known as montunos in North America, or tumbaos in the contemporary Cuban dance music timba.
Traditional sub-Saharan African harmony is a music theory of harmony in Sub-Saharan Africa music based on the principles of homophonic parallelism, homophonic polyphony, counter melody and ostinato-variation. Polyphony is common in African music and heterophony is a common technique as well. Although these principles of traditional African music are of Pan-African validity, the degree to which they are used in one area over another varies. Specific techniques that used to generate harmony in Africa are the "span process", "pedal notes", "Rhythmic harmony", "harmony by imitation", and "scalar clusters".
