Composition found amongst some papers on a table (6)
I believe the answer is:
sonata
'composition' is the definition.
(type of musical composition)
'amongst some papers on a table' is the wordplay.
'amongst' says the answer is hidden in the clue.
'SONATA' is hidden in the letters of 'some papers on a table'.
'found' acts as a link.
(Other definitions for sonata that I've seen before include "just for one or two players?" , "To NASA, strangely, for the solo piece" , "Music to play (not sing)" , "eg Moonlight, Kreutzer" , "Musical composition for one or two instruments" .)
