College - sham without English style of music (9)
I believe the answer is:
polyphony
'style of music' is the definition.
(I've seen this before)
'college sham' is the wordplay.
'college' becomes 'poly' (polytechnic).
'sham' becomes 'phony' (I've seen this in another clue).
'poly'+'phony'='POLYPHONY'
'without english' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for polyphony that I've seen before include "musical style" , "style of music" .)
