VAMethod is built on the principles of functional voice training developed by Cornelius Reid, the most influential vocal theorist of the twentieth century. Its core principle: the vocal organ is largely involuntary, responding instinctively when the brain forms a mental image of a sound. So instead of isolated anatomical cues like “raise your larynx” or “reduce vocal mass,” VAMethod works through the relationship between musical elements — pitch, vowel, and intensity — and vocal behavior. By giving the voice musical instructions rather than anatomical ones, it activates a logical sequence of development for voice feminization and masculinization.
