Composer's catalogue heard (5)
I believe the answer is:
liszt
'composer's' is the definition.
(Franz Liszt)
'catalogue heard' is the wordplay.
'catalogue' becomes 'list' (a catalogue is a list of items).
'heard' shows a homophone (sound like).
'list' is a homophone of 'LISZT'.
(Other definitions for liszt that I've seen before include "Composer of the Hungarian Rhapsodies" , "Pianist and composer (often associated with Brahms), d. 1886" , "with his partner, drunk?" , "Pianist, father of Cosima Wagner" , "Hungarian composer,d. 1886" .)
