Accompaniment, musical terminology, instrumental music that accompanies singing. The accompaniment of Peking Opera singing is mainly Jinghu, the main instrument, and the accompaniment method is full of singing and following. That is to say, the accompaniment is basically the same as the singing tune, and there can also be a variety of decorative sounds or high and low octave covers. The accompanist must also play purely instrumental parts such as fill-ins to connect the lyrics. Singing music usually refers to band accompaniment with the lead instrument as the main instrument.

For vocal music, the part other than the vocal is called accompaniment. For pure music, there is no such thing as accompaniment.
