Musical piece from Lohengrin, one thinks (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
nonet
'musical piece' is the definition.
(I've seen this before)
'from lohengrin one thinks' is the wordplay.
'from' indicates the answer is hidden within the clue.
'NONET' is hidden in the letters of 'lohengrin one thinks'.
(Other definitions for nonet that I've seen before include "Ennead" , "Composition for nine instruments" , "Piece for group" , "Tenon (anag.)" , "Band's" .)
