Music-maker such as ear drum put first (6,5)
I believe the answer is:
barrel organ
'music-maker such as ear drum' is the definition.
I can't judge whether this definition defines the answer.
'put first' is the wordplay.
'put' becomes 'barrel' (barreling is a kind of putting).
'first' becomes 'organ' (I am not sure about this - if you are sure you should believe this answer much more).
'barrel'+'organ'='BARREL-ORGAN'
Can you help me to learn more?
(Other definitions for barrel organ that I've seen before include "Mechanical instrument" , "that's instrumental" , "Hurdy-gurdy" , "one's notes will be right if uninspired" , "Musical instrument, with 10?" .)
