About musical piece of furniture (5)
I believe the answer is:
chair
'piece of furniture' is the definition.
(chair is a kind of piece of furniture)
'about musical' is the wordplay.
'about' becomes 'c' (abbreviation for 'circa').
'musical' becomes 'hair' (I've seen this before).
'c'+'hair'='CHAIR'
(Other definitions for chair that I've seen before include "See 4" , "Top seat of committee" , "Movable seat" , "A committee's most important seat" , "Supporter" .)
