Crate bound by stripped narrow raised band (9)
I believe the answer is:
orchestra
'band' is the definition.
(musical band)
'crate bound by stripped narrow raised' is the wordplay.
'crate' becomes 'chest' (both can mean a large container).
'bound by' means one lot of letters goes inside another (I've seen this in other clues).
'stripped' means to look at the middle letters.
'raised' is a reversal indicator (going up in a down clue).
The middle letters of 'narrow' are 'arro'.
'arro' written backwards gives 'orra'.
'chest' placed into 'orra' is 'ORCHESTRA'.
(Other definitions for orchestra that I've seen before include "Large group of musicians" , "Large body of musicians" , "Group of musical instrumentalists" , "Large band of players" , "Large group of players" .)
