What was the musical scale used in ancient chinese compositions called?

a: minor

b: major

c: pentatonic

d: dominant

(i think it's c or b)

The answer is C.

Explanation:

The musical scale they used in Ancient Chinese compositions is called, the "pentatonic scale".

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
