A quick grasp of music (6)
I believe the answer is:
snatch
'a quick grasp' is the definition.
'snatch' can be an answer for 'grasp' (I've seen this before). I'm unsure of the 'a quick' bit.
'music' is the wordplay.
I cannot really understand how this works, but
'music' could be 'c' and 'c' is located in the answer.
The remaining letters 'snath' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for snatch that I've seen before include "E. Mediterranean nation" , "Grab, seize eagerly" , "Grab suddenly" , "Grab or kidnap" , "Seize quickly and eagerly" .)
