End of music used by disco dancers (4)
I believe the answer is:
coda
'end of music' is the definition.
'coda' can be an answer for 'end' (I've seen this before). I am not certain of the 'of music' bit.
'used by disco dancers' is the wordplay.
'used by' indicates a hidden word.
'CODA' can be found hidden inside 'disco dancers'.
Can you help me to learn more?
(Other definitions for coda that I've seen before include "Passage of piece of music added to the end" , "Closing passage of musical piece" , "End piece written for a musical work" , "tail" , "End of movement" .)
