Which type of music features a vocal quartet in which each voice has its own role, and the bass singer handles the repeated foundation part, often in the form of a short phrase of nonsense syllables?

c, d, e, f, g, a, b, and c.

sometimes western music will also use solfege. the names of these are do ra me fa sol la si (or ti) and do.

to indicate a note a half step higher or lower then the original note, you would say c # (for a half a step above c) or bb (for half a step below b)

i dont think it is true
