Description

An examination of the historical treatises of Manuel Garcia II and Giambattista Mancini, scientific studies pertaining to glottal closure, and Vocal Function Exercises used in clinical speech pathology led to an exploratory study that attempted to increase the glottal closure in an untrained university male chorus using only choral voice building exercises. The exploratory study used a single group, pre-test post-test design, and data was recorded using audio recordings of the entire chorus as well as electroglottograph measurements of individual subjects. The data show an increase in glottal closure as measured by closed quotient values, and an increase in energy … continued below

The data show an increase in glottal closure as measured by closed quotient values, and an increase in energy in the upper partials of the recorded acoustic signal from the chorus.
