The vibrato rate for ten singers, all singing Schubert’s Ave Maria, was measured on sonograms. Commercially available CD records were used to insure that the vibrato originated in a real musical performance. It was found, that the vibrato rate typically increased at the end of each tone, +15% in average, while no typical structure could be found in the beginning of a tone. Disregarding the increase of vibrato rate toward tone endings, the mean rate across singers was 6.0 Hz. The average…

Measurements of vibrato parameters in long sustained crescendo notes as sung by ten sopranos.

Two high-pitched and long sustained notes, F5 and A5, were selected from an aria found in ten commercial recordings of G Verdi's opera Aida by ten different sopranos and reveal that vibrato rate differed significantly between the tones in most of the singers and confirm Prame's observations that vibrator rate tends to increase exponentially toward the end of tones.

Automated evaluation of singers' vibrato through time and frequency analysis of the pitch contour using the DSK6713

Vibrato is a musical effect produced in singing and in playing of musical instruments, serving to enrich the musical sound and is used to add expression and vocal-like qualities to instrumental music.

Rhythmic aspects of vibrato

Vibrato, the periodic fluctuation in pitch, amplitude, and/or timbre of a musical tone, is an important expressive component of musical performance. Especially singers and string players use vibrato

Vibrato extent and intonation in professional Western lyric singing

Two important aspects of singers’ F0 control have been investigated: vibrato extent and intonation. From ten commercially available compact disc recordings of F. Schubert’s Ave Maria, 25 tones were

Qualities of a voice emeritus

The effects of vocal ageing are investigated in a professional mezzo-soprano singer, for which the phonetogram, and 45 vowels, each sung at fundamental frequencies of 220, 392, and 659 Hz, were

Assessing vibrato quality of singing students

V vibrato quality in sustained notes as sung by students, rather than professionals, is examined in an attempt to find objective measures for assessing vibratoquality in singing students.

Analysis for Vibrato with Arbitrary Shape and its Applications to Music

Vibrato in singing voice and instrument performance is essential for perceived quality. It also creates individual performer styles. Over the years, vocal teachers and musicians often examine this

The physics of singing vibrato

A spectrogram of a singer’s vibrato presents a striking way to introduce students to frequency, Fourier spectra, and modulation. Vibrato is discussed from the perspectives of the physicist and the



Physiologic factors in vocal vibrato

Vocal vibrato when produced on a sustained vowel with constant subglottal air pressure is made up principally of fundamental frequency oscillations about the target pitch. This type of phonation was
