A study of the first five cycles of vibrato production ("vibrato onset") in five male singers suggests that there is considerable variety in such variables as vibrato range, vibrato cycle, onset excursion and timing of appearance of initial F0 and energy peaks among both trained and untrained voices. Vibrato onsets serve as a diagnostic for overall setting of individual singing mechanisms just prior to voice production and also suggest that this overall setting is an important factor in establishing a good vibrato.
