Accomplished chaps left to compose something tuneful (7)
I believe the answer is:
melodic
'tuneful' is the definition.
(I've seen this before)
'accomplished chaps left to compose' is the wordplay.
'left' suggests deleting specific letters (some letters have left).
'to compose' is an anagram indicator.
'accomplished' with 'chaps' taken out is 'comlied'.
'comlied' with letters rearranged gives 'MELODIC'.
'something' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for melodic that I've seen before include "Old mice (anag.)" , "Pleasantly musical" , "Harmonious" , "Pleasant-sounding" , "nice on the ear" .)
