Lot more about variation in pitch (7)

Ross

I believe the answer is:

tremolo

'variation in pitch' is the definition.

'lot more about' is the wordplay.
'about' indicates an anagram.
'lot'+'more'='lotmore'
'lotmore' anagrammed gives 'TREMOLO'.

(Other definitions for tremolo that I've seen before include "Vibrato effect" , "Unsteady effect" , "Musically shivering" , "Wavering effect in music" , "A vibrating effect in music" .)

I've seen this clue in The Daily Express and The Mirror.
