English composer providing part for violin that's played by quartets (6)
I believe the answer is:
bridge
'english composer' is the definition.
(I've seen this before)
'part for violin that's played by quartets' is the wordplay.
I cannot quite see how this works, but
'part' could be 'ridge' (I have seen 'Part of mountain' mean 'ridge' so perhaps 'part' could also mean 'ridge') and 'ridge' is found within the answer.
A single letter 'b' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for bridge that I've seen before include "Structure spanning a divide" , "Crossing point" , "Join" , "Game; crossing" , "Where the ship is steered and the captain stands" .)
