Music played staccato needing no introduction (7)
I believe the answer is:
toccata
'music' is the definition.
(toccata is a kind of music)
'played staccato needing no introduction' is the wordplay.
'played' indicates an anagram.
'needing no introduction' means to remove the first letter.
'staccato' with its initial letter taken away is 'taccato'.
'taccato' anagrammed gives 'TOCCATA'.
(Other definitions for toccata that I've seen before include "lively piece" , "Flashy piece of music" , "Musical work designed to show player's technique" , "Touching piece" , "Baroque musical composition" .)
