Chant

Chant sounded with only sub-harmonic

“Technique of singing an octave multiphonic, i.e., one voice producing simultaneously two pitches one octave apart. The vocalist’s sensation is  that of a light singing tone (upper pitch) combined with vocal fry (lower pitch, "locks  into place" ). Low-pitched chant with a strong reinforced harmonic above the octave multiphonic resembles that used in Tibetan Tantric Bhuddist (sic) schools.” ( Leonard, 50)

“To execute the simple octave chant, one sounds a light, low fundamental and enters a vocal fry on the pitch of the original tone. The tone “splits” apart and the sub-octave will sound,” requiring steady airflow. (Leonard, 54)
