Summary

Singers can adjust their vocal vibrato rate to match target speeds. Slower vibrato correlated with lower intensity, while faster vibrato increased intensity and extent, potentially enhancing vocal performance.

Area of Science:

  • Vocal acoustics
  • Singing physiology

Background:

  • Vocal vibrato is a crucial element of singing.
  • Understanding vibrato modulation is key for vocal pedagogy.

Purpose of the Study:

  • To document acoustic changes during singing vibrato rate modification.
  • To investigate singers' ability to match target vibrato rates.

Main Methods:

  • Eight advanced singing students produced vowels in three registers.
  • Vibrato rate was modulated naturally and to match faster/slower target stimuli.
  • Acoustic parameters like intensity and extent were analyzed.

Main Results:

  • Slower vibrato rates were linked to reduced intensity and stability.
  • Faster vibrato rates increased vibrato extent (chest register) and intensity (head register).
  • Individual natural vibrato tendencies influenced modulation ability.

Conclusions:

  • Singers exhibit varying degrees of control over vibrato rate.
  • Modulating vibrato rate can impact vocal intensity and extent.
  • This control may positively influence the artistic quality of singing.
