Can anyone solve this sight reading for me please? It’s in the key of B-flat (major) please answer in (Do, Re, Mi..etc)

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 believe their role is to instruct certain sections on when they are to join and when they are to stop
