"The bass note which the Gyuto monks chant is two octaves below middle C, vibrating at an astounding 75.5 cycles per second. This first note seems to be a sub-harmonic or an undertone of a note that is an octave below the fundamental tone. The monks also create another very distinct note, a harmonic which is two octaves and a third higher than that bass note, making a D#. The 5th and the 10th harmonics are also pronounced but less distinct." ~Jonathan Goldman, Healing Sounds
