Someone who is an expert at 3 or more classes of musical instruments (including the use of vocals) may also be called a polymuse.
Someone who listens to wide variety of music genres may refer to themselves as a polymuse though to a much lesser degree due to the fact that the average person listens to wide variety of genres in the first place.
A one man band is a polymuse.
Not to be confused with audiophile.
Aldrich: You call that singing? Avril is old hat!
Abbie: Beethoven is a bit of a polymuse. He plays the organ, piano and the violin but an organ and a piano is in the same class of instruments so...
POLY means many.
MUSE means music.
so it literally translates to "many music".
it means you like a lot of different styles of music.
it's good to be a polymuse.
opposite is a monomuse
i'd say the majority of the people are polymuses.
