Body parts and musical instruments (6)
I believe the answer is:
organs
'body parts and musical instruments' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for organs that I've seen before include "Air-powered keyboard instruments" , "Heart and lungs are vital ones" , "Functional parts of the body, or musical instruments" , "newspapers" , "Periodicals published by special interest groups" .)
