A cappella music is a performance by a singer or a singing group without instrumental accompaniment, or a piece intended to be performed in this fashion. The term a cappella was originally intended to differentiate between Renaissance polyphony and Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music. The term is also used, rarely, as a synonym for alla breve.
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. Definitions of music vary depending on culture, though it is an aspect of all human societies and a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice.
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.
Doo-wop is a genre of rhythm and blues music that originated in African-American communities during the 1940s, mainly in the large cities of the United States, including New York, Philadelphia, Pittsburgh, Chicago, Baltimore, Newark, Detroit, Washington, D.C., and Los Angeles. It features vocal group harmony that carries an engaging melodic line to a simple beat with little or no instrumentation. Lyrics are simple, usually about love, sung by a lead vocal over background vocals, and often featuring, in the bridge, a melodramatically heartfelt recitative addressed to the beloved. Harmonic singing of nonsense syllables is a common characteristic of these songs. Gaining popularity in the 1950s, doo-wop was "artistically and commercially viable" until the early 1960s, but continued to influence performers in other genres.
A barbershop quartet is a group of four singers who sing music in the barbershop style, characterized by four-part harmony without instrumental accompaniment, or a cappella. The four voices are: the lead, the vocal part which typically carries the melody; a bass, the part which provides the bass line to the melody; a tenor, the part which harmonizes above the lead; and a baritone, the part that frequently completes the chord. The baritone normally sings just below the lead singer, sometimes just above as the harmony requires. Barbershop music is typified by close harmony— the upper three voices generally remain within one octave of each other.
A chord is in close harmony if its notes are arranged within a narrow range, usually with no more than an octave between the top and bottom notes. In contrast, a chord is in open harmony if there is more than an octave between the top and bottom notes. The more general term spacing describes how far apart the notes in a chord are voiced. A triad in close harmony has compact spacing, while one in open harmony has wider spacing.
Barbershop vocal harmony, as codified during the barbershop revival era (1930s–present), is a style of a cappella close harmony, or unaccompanied vocal music, characterized by consonant four-part chords for every melody note in a primarily homorhythmic texture. Each of the four parts has its own role: generally, the lead sings the melody, the tenor harmonizes above the melody, the bass sings the lowest harmonizing notes, and the baritone completes the chord, usually below the lead. The melody is not usually sung by the tenor or baritone, except for an infrequent note or two to avoid awkward voice leading, in tags or codas, or when some appropriate embellishment can be created. One characteristic feature of barbershop harmony is the use of what is known as "snakes" and "swipes". This is when a chord is altered by a change in one or more non-melodic voices. Occasional passages may be sung by fewer than four voice parts.
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.
A vocal group is a performing ensemble of vocalists who sing and harmonize together. The first well-known vocals groups emerged in the 19th century, and the style had reached widespread popularity by the 1940s.
A rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band. The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody.
Deke Sharon is an American singer, arranger, composer, director, producer, pioneer, and teacher of a cappella music, and is one of the leaders and promoters of the contemporary a cappella community. He has been referred to as "the father of contemporary a cappella" by some authors, and "the godfather of a cappella" by others.
The Contemporary A Cappella Society, or CASA, is a 501(c)(3) charitable organization dedicated to fostering and promoting a cappella music of all styles around the world. CASA was founded in 1991 by Deke Sharon in San Francisco just after graduation. In his Tufts University dorm room during his senior year, Sharon published a newsletter, The "C.A.N.", mailed to all known collegiate a cappella groups by merging "The List," founded in 1988 & distributed by Rex Solomon, with the database maintained by his college a cappella group the Beelzebubs. The organization boasts over 6,000 current members, and serves as a resource for media and scholarly work in the area of contemporary a cappella.
"Dogs" is a song by English progressive rock band Pink Floyd, released on the album Animals in 1977. This song was one of several to be considered for the band's 2001 compilation album Echoes: The Best of Pink Floyd.
Barbershop arranging is the art of creating arrangements of barbershop music. The Barbershop Harmony Society (BHS) and Sweet Adelines International (SAI) have prescribed rules that dictate what is an acceptable arrangement, particularly with regard to singing in competition. This makes barbershop arranging a specialist form of arranging, rarely tackled by those outside barbershop; likewise, barbershop arrangers tend to be known only for their barbershop arrangements rather than for their work in any other musical form.
A vocal coach, also known as a voice coach, is a music teacher, usually a piano accompanist, who helps singers prepare for a performance, often also helping them to improve their singing technique and take care of and develop their voice, but is not the same as a singing teacher. Vocal coaches may give private music lessons or group workshops or masterclasses to singers. They may also coach singers who are rehearsing on stage, or who are singing during a recording session. Vocal coaches are used in both classical music and in popular music styles such as rock and gospel. While some vocal coaches provide a range of instruction on singing techniques, others specialize in areas such as breathing techniques or diction and pronunciation.
The Harmony Sweepstakes A Cappella Festival is an annual showcase and competition for a cappella groups of all vocal styles. The competition is organized into seven regional events across the United States, with each winning group advancing to the National Finals in San Rafael, California.
Non-lexical vocables, which may be mixed with meaningful text, are a form of nonsense syllable used in a wide variety of music. Common English examples are "la la la", "na na na" and "da da da".

Traditional sub-Saharan African harmony is a music theory of harmony in sub-Saharan African 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".
