How is vibrato measured?
An estimated vibrato frequency is calculated by taking the mean of the frequency intensities (in essentially the same way that mean frequency is calculated. The vibrato amplitude is calculated as the peak amplitude of the spectrum.
What frequency is vibrato?
Vibrato is constituted by a (predominantly regular) modulation of the singing fundamental frequency, typically in the range of 4–7 Hz (10. Physiological aspects of vibrato.
Does vibrato change frequency?
Graphically, vibrato changes the frequency of a waveform. Tremolo is volume variation. The sound of tremolo represents slight fluctuations in volume. Singers can produce a tremolo effect by adjusting the airflow through their vocal tract.
Is vibrato Natural or learned?
It occurs naturally in order to protect the vocal folds. The oscillations that occur in vibrato are the body's reflexive response to mounting tension, and are believed to be the result of the healthy function of the vocal folds. The tension of the vocal folds is varied rhythmically, creating movement in pitch.
