What is Accompaniment?

The accompaniment is the musical part that provides the rhythmic and harmonic support to music. Accompaniment varies from music genre and style. An accompanist is a musician who plays an accompaniment part in a song.

” 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. The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can, in theory, be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). A solo singer can accompany herself by playing guitar or piano while she sings, and in some rare cases, a solo singer can even accompany himself or herself just using his or her voice and body (e.g., Bobby McFerrin).

Alternatively, the accompaniment to a vocal melody or instrumental solo can be provided by a musical ensemble, ranging in size from a duo (e.g., cello and piano; guitar and double bass; synthesizer and percussion); a trio (e.g., a rock power trio of electric guitar, electric bass and drum kit; an organ trio); a quartet (e.g., a string quartet in Classical music can accompany a solo singer; a rock band or rhythm section in rock and pop; a jazz quartet in jazz); all the way to larger ensembles, such as concert bands, Big Bands (in jazz), pit orchestras in musical theatre; and orchestras, which, in addition to playing symphonies, can also provide accompaniment to a concertosolo instrumentalist or to solo singers in opera. With choral music, the accompaniment to a vocal solo can be provided by other singers in the choir, who sing harmony parts or countermelodies. Accompaniment parts range from so simple that a beginner can play them (e.g., simple three-note triad chords in a traditional folk song) to so complex that only an advanced player or singer can perform them (e.g., the piano parts in Schubert’s Lieder art songs from the 19th century or vocal parts from a Renaissance music motet).” Source: https://en.wikipedia.org/wiki/Accompaniment
