Extended data

In solo or solo, only one voice plays a role, such as tenor solo and mezzo-soprano solo. In chorus and instrumental ensemble, music consists of multiple parts, usually one melody part plays the role of main melody, and other parts play the role of accompaniment. In polyphonic music, sometimes two or more voices show multiple independent melodies at the same time, and these melodies are intertwined, showing two contradictory sides of the music theme.

In terms of music score, notation is carried out in the form of a large music score table. From high to low, there are soprano (or tenor), alto (or alto), tenor (or tenor) and bass (or bass).

Tenor, tenor and tenor are collectively called "upper three parts", alto and bass are collectively called "outer parts", alto and tenor are collectively called "inner parts", and the highest part is also called "melody parts".
