Formant Tuning in Your Ensemble, Demystified
Hall, Donald E. Musical Acoustics. 3rd ed. Pacific Grove, CA: Brooks/Cole Publishing, 2001, p. 310.
Summary
The non-linear source-filter theory of vocal production posits that certain combinations of vowels and pitches create unusually powerful resonances. This knowledge can be employed by choral directors to help singers produce beautiful sounds in the most vocally healthy way possible.
Handouts
Some of the best information on formants that I have found comes from Scott McCoy’s book, Your Voice: An Inside View.
