Piece played staccato with no introduction (7)
I believe the answer is:
toccata
'piece' is the definition.
(I know that toccata is a type of piece)
'played staccato with no introduction' is the wordplay.
'played' indicates anagramming the letters.
'with no introduction' means to remove the first letter.
'staccato' with its initial letter taken off is 'taccato'.
'taccato' anagrammed gives 'TOCCATA'.
(Other definitions for toccata that I've seen before include "Noted work" , "Musical composition for keyboard to show technique" , "lively piece" , "Baroque musical composition" , "Keyboard composition emphasising technique" .)
