Who were the three posts impressionist

The main post-impressionist painters were Paul Cezanne, Paul Gauguin, Vincent van Gogh, Georges Seurat, Henri Toulouse-Lautrec and Henri Rousseau ('Le Douanier').

Explanation:

tbh, either pop or, i know it's not on the list, but indie/ alternative.

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)
