Rapid variation in pitch (7)

I believe the answer is:

vibrato

(Other definitions for vibrato that I've seen before include "Oscillatory effect" , "Rapid alternation in pitch" , "Pulsating effect in instrumental or vocal tone" , "Singing effect" , "Rapid pitch variation" .)

I've seen this clue in The Times.
