The following is an introduction to accompaniment:

Accompaniment, musical terminology, instrumental performance accompanied by singing. The singing accompaniment of Beijing Opera is mainly the main instrument Jinghu, and the accompaniment method is full of heels. That is, accompaniment and singing are basically the same, and there can be a variety of decorative sounds or high and low octaves. ?

The task of accompaniment must also play the role of pure musical instruments such as doors to connect the singing sentences. Generally speaking, vocal music includes the accompaniment of the main instrument. For vocal music, the part other than human voice is called accompaniment. For pure music, there is no such thing as accompaniment.

Usually it mainly ends with "1" and secondly with "6". If the outcome is not, it may be a national model. G 7 can be used before the termination of the whole song and phrase to achieve a clearer termination effect. Taking C major as an example, using G or G7 before C can achieve a perfect termination effect.
