Twist music (6)
I believe the answer is:
strain
This clue is a double definition.
'twist' is the first definition.
(I've seen this before)
'music' is the second definition.
(strain is a kind of music)
(Other definitions for strain that I've seen before include "Pour through a sieve" , "Overtired" , "Force - melody" , "Race" , "Great effort - sieve" .)
