A tremulous or pulsating effect produced in an instrumental or vocal tone by minute and rapid variations in pitch.
A pulsating effect, less extreme than a tremolo, produced by rapid alternation of a given tone with a barely perceptible variation in pitch, as by the slight oscillation of the finger on a violin string or by a slight wavering of the tone in singing.
(music) The musical effect or technique where the pitch or frequency of a note or sound is quickly and repeatedly raised and lowered over a small distance for the duration of that note or sound.
