A solo singer can accompany themself by playing guitar or piano while they sing, and in some rare cases, a solo singer can even accompany themself just using their voice and body (e.g., Bobby McFerrin).

Notation and improvisation

The accompaniment instrumentalists and/or singers can be provided with a fully notated accompaniment part written or printed on sheet music. This is the norm in

and in most large ensemble writing (e.g.,

, pit orchestra,

). In

and

, the accompaniment instrumentalists often improvise their accompaniment, either based on a lead sheet or chord chart which indicates the chords used in the

or piece (e.g., C Major, d minor, G7, or Nashville Numbers or Roman numerals, such as I, ii, V7, etc.) or by " playing by ear". To achieve a stylistic correct sound the accompaniment pattern should remind or imitate the original version using similar rhythms and patterns. Chord-playing musicians (e.g., those playing

, Hammond organ, etc.) can improvise chords, "fill-in" melodic lines and solos from the chord chart. It is rare for chords to be fully written out in music notation in pop and traditional music. Some guitarists, bassists and other stringed instrumentalists read accompaniment parts using
