Let room out for musical effect (7)

Ross

I believe the answer is:

tremolo

'musical effect' is the definition.
(I've seen this before)

'let room out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'let'+'room'='letroom'
'letroom' is an anagram of 'TREMOLO'.

'for' acts as a link.

(Other definitions for tremolo that I've seen before include "Vocal vibrato -- lot more (anag)" , "Musical shake" , "effect of repeated bowing" , "Violin's rapid repetition of a single note" , "Quivering effect (in music)" .)

I've seen this clue in The Daily Express.
