No chance to compose a stately dance tune (8)
I believe the answer is:
chaconne
'a stately dance tune' is the definition.
(type of musical composition)
'no chance to compose' is the wordplay.
'to compose' indicates an anagram.
'no'+'chance'='nochance'
'nochance' is an anagram of 'CHACONNE'.
(Other definitions for chaconne that I've seen before include "Stately dance" , "Slow dance" , "Composition" , "Music for Spanish dancing" .)
