Music is the art of arranging sounds in time through the elements of melody, harmony, rhythm, and timbre. It is one of the universal cultural aspects of all human societies. General definitions of music include common elements such as pitch, rhythm, dynamics, and the sonic qualities of timbre and texture. Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική.
Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry" generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds ; to several minutes or hours, or, at the most extreme, even over many years.
Music theory is the study of the practices and possibilities of music. The Oxford Companion to Music describes three interrelated uses of the term "music theory". The first is the "rudiments", that are needed to understand music notation ; the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built."

Given the vastness of the African continent, its music is diverse, with regions and nations having many distinct musical traditions. African music includes the genres Jùjú, Fuji, Highlife, Makossa, Kizomba, Afrobeat and others. The music and dance of the African diaspora, formed to varying degrees on African musical traditions, include American music like Dixieland, the blues, jazz, old-time, and bluegrass and many Caribbean genres, such as calypso and soca. Latin American music genres such as zouk, bomba, conga, rumba, son cubano, salsa music, cumbia and samba, were founded on the music of enslaved Africans, and have in turn influenced African popular music.
In music, an ostinato[ostiˈnaːto] 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), The Who's Baba O'Riley and The Verve's "Bitter Sweet Symphony" (1997).
A suite, in Western classical music and jazz, is an ordered set of instrumental or orchestral/concert band pieces. It originated in the late 14th century as a pairing of dance tunes and grew in scope to comprise up to five dances, sometimes with a prelude, by the early 17th century. The separate movements were often thematically and tonally linked. The term can also be used to refer to similar forms in other musical traditions, such as the Turkish fasıl and the Arab nuubaat.
The clave is a rhythmic pattern used as a tool for temporal organization in Afro-Cuban music. In Spanish, clave literally means key, clef, code, or keystone. It is present in a variety of genres such as Abakuá music, rumba, conga, son, mambo, salsa, songo, timba and Afro-Cuban jazz. The five-stroke clave pattern represents the structural core of many Afro-Cuban rhythms.
In music, form refers to the structure of a musical composition or performance. In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments, or the way a symphonic piece is orchestrated", among other factors.
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.
In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these.
The Music of Java embraces a wide variety of styles, both traditional and contemporary, reflecting the diversity of the island and its lengthy history. Apart from traditional forms that maintain connections to musical styles many centuries old, there are also many unique styles and conventions which combine elements from many other regional influences, including those of neighbouring Asian cultures and European colonial forms.
In music, the term period refers to certain types of recurrence in small-scale formal structure. In twentieth-century music scholarship, the term is usually used as defined by the Oxford Companion to Music: "a period consists of two phrases, antecedent and consequent, each of which begins with the same basic motif." Earlier usage varied somewhat, but usually referred to similar notions of symmetry, recurrence, and closure. The concept of a musical period originates in comparisons between music structure and rhetoric at least as early as the 16th century.
Islamic music may refer to religious music, as performed in Islamic public services or private devotions, or more generally to musical traditions of the Muslim world. The heartland of Islam is the Middle East, North Africa, the Horn of Africa, West Africa, Iran, Central Asia, and South Asia. Due to Islam being a multi-ethnic religion, the musical expression of its adherents is vastly diverse. Indigenous traditions of various part have influenced the musical styles popular among Muslims today. The word "music" in Arabic, the language of Islam, is defined more narrowly than in English or some other languages, and "its concept" was at least originally "reserved for secular art music; separate names and concepts belonged to folk songs and to religious chants".)
A level, also "tonality level", Gerhard Kubik's "tonal step," "tonal block," and John Blacking's "root progression," is an important melodic and harmonic progression where melodic material shifts between a whole tone above and a whole tone below the tonal center. This shift can occur to both neighboring notes, in either direction, and from any point of departure. The steps above and below the tonic are often called contrasting steps. A new harmonic segment is created which then changes the tonality but not necessarily the key.
Colotomy is an Indonesian description of the rhythmic and metric patterns of gamelan music. It refers to the use of specific instruments to mark off nested time intervals, or the process of dividing rhythmic time into such nested cycles. In the gamelan, this is usually done by gongs of various size: the kempyang, ketuk, kempul, kenong, gong suwukan, and gong ageng. The fast-playing instruments, kempyang and ketuk, keep a regular beat. The larger gongs group together these hits into larger groupings, playing once per each grouping. The largest gong, the gong ageng, represents the largest time cycle and generally indicates that that section will be repeated, or the piece will move on to a new section.
A bell pattern is a rhythmic pattern of striking a hand-held bell or other instrument of the idiophone family, to make it emit a sound at desired intervals. It is often a key pattern, in most cases it is a metal bell, such as an agogô, gankoqui, or cowbell, or a hollowed piece of wood, or wooden claves. In band music, bell patterns are also played on the metal shell of the timbales, and drum kit cymbals.
In music, a cross-beat or cross-rhythm is a specific form of polyrhythm. The term cross rhythm was introduced in 1934 by the musicologist Arthur Morris Jones (1889–1980). It refers to when the rhythmic conflict found in polyrhythms is the basis of an entire musical piece.
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".
