Music rooms? (5)
I believe the answer is:
suite
I believe this is a double definition.
'music' is the first definition.
(suite is a kind of music)
'rooms?' is the second definition.
(synonyms)
(Other definitions for suite that I've seen before include "Adjoining rooms" , "Compensate for (faults)" , "Train; set of rooms" , "Set of rooms; retinue" , "music collection" .)
