Composition that's not out of the way? (5)
I believe the answer is:
nonet
'composition' is the definition.
(I've seen this in another clue)
'that's not out of the way?' is the wordplay.
'that's not' becomes 'non' (I've seen this in other clues).
'out of' indicates anagramming the letters.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'way?' becomes 'e' (Compass direction - East).
't'+'e'='te'
'te' with letters rearranged gives 'et'.
'non'+'et'='NONET'
(Other definitions for nonet that I've seen before include "Band's" , "Instrumental group of nine players" , "piece to be performed" , "Music for nine instruments or voices" , "Ennead" .)
