Name a composer heard (6)
I believe the answer is:
handle
'name' is the definition.
(a handle is a name)
'a composer heard' is the wordplay.
'a composer' becomes 'handel' (George Frideric Handel).
'heard' shows a homophone (sound like).
'handel' is a homophone of 'HANDLE'.
(Other definitions for handle that I've seen before include "Cope with" , "Control - deal with - write about" , "Manage or deal with - in manual way?" , "Part by which something is held" , "Manipulate; manage" .)
