Bozeman (voice and voice science and pedagogy, Lawrence U.) synthesizes insights and principles from voice research regarding the acoustics of vocal registration and details their pedagogic implications for voice teachers and students. He explains harmonics, theories of vocal resonance, the basics of formants, harmonic/formant interactions, female/treble voice resonance strategies, male passaggio training, perceptions of when a voice turns over, the pedagogic implications of vocal tract acoustics, pedagogic strategies that encourage stability and a convergent resonator, the acoustics of belting, terminology, and vocal explorations and exercises for vowel turning and first formant/first harmonic (F1/H1) tracking, as well as supplemental strategies. He also discusses laryngeal registration and the use of the Madde voice synthesizer and the VoceVista sound analysis program in instruction. He does not address non-acoustic aspects of singing, and focuses on the Western classical singing tradition. The DVD contains 12 sample explorations of vowel turning and F1/H1 tracking with undergraduate students. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
