Muse of music (7)
I believe the answer is:
euterpe
'muse of music' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for euterpe that I've seen before include "Musical Muse" , "Muse of lyric poetry and music" , "inspiring female" , "Inspiration for writer" , "One of the Muses" .)
