Music maker's home in Bordeaux (8)
I believe the answer is:
clarinet
'music maker's' is the definition.
(clarinet is a kind of musical instrument)
'home in bordeaux' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'in' is an insertion indicator.
'bordeaux' becomes 'claret' (I've seen this before).
'in' placed inside 'claret' is 'CLARINET'.
(Other definitions for clarinet that I've seen before include "Instrument in claret, strangely" , "member of orchestra" , "Musical wind instrument as played by Benny Goodman" , "It's for playing" , "Find an instrument in claret" .)
