This resonance vowel chart is an amalgam of common vowel charts that appear in pedagogical texts which attempt to describe how the resonating spaces are shaped by a system and sequence of vowels for optimum resonance, with research by Berton Coffin and others. The result is a pitch specific system of resonating vowels that encourage optimal resonance at varied frequencies. The benefits include, but are not limited to:
-This chart is neither age nor gender specific. Therefore, it can be used throughout adolescent voice changes, which is particularly useful for adolescent boys as their voices drop in pitch. No matter the type or speed of voice change being experienced, teachers can help the singer access resonance as new pitches develop.
-Tracking the movement of vowels throughout varied registers, gives singers a physical sensation of closing and opening, and encourages even inexperienced singers to access chiaroscuro.
-Recent data indicates that this process also encourages an increase in the singer’s formant, and decreases the need for issues of vowel modification, and blend.
Most recently my research is pointing toward how this chart may be useful for senescent, or aging changing voices.
