Vocal Tech is an interactive guide to classical singing. It is intended for students of classical vocal music: opera, oratorio, song literature, etc. Any student of singing hoping to build a solid technical foundation can use Vocal Tech. The app discusses Phonation, Resonance, Posture, and Breathing. It includes vocal exercises with recorded examples and a voice recorder for the student. A tenured university professor with a doctorate in voice performance and vocal pedagogy created Vocal Tech.
