Musical piece from 'Chess' on a tape (6)
I believe the answer is:
sonata
'musical piece' is the definition.
(I've seen this before)
'from chess on a tape' is the wordplay.
'from' indicates a hidden word.
'SONATA' is hidden in the letters of 'chess on a tape'.
(Other definitions for sonata that I've seen before include "See 6" , "Musical piece" , "Piece of music for solo piano" , "Solo piano composition" , "Classical composition" .)
