Voice Type Definitions
Operatic. Institutionally/ academically trained ‘singers’ formant’ voice, with wide continuous vibrato, low larynx production (generating a dark and plummy sound, especially noticeable from male singers and capable of high volume).
Early Music Mainstream. A higher larynx position than used by the operatic voice, with narrow but more or less continuous vibrato, producing a sound midway between Categories A and C, with generally lower volume.
Clear Smooth Sweet Chaste. Fairly soft, straight tone, without vibrato except as an ornament. No low larynx delivery, producing a sound close to the speaking voice.
