I usually write at my own blog at www.klang440.org, but since this is a very overtone-related post, I've copied it here as well.

=============







Ever since I stopped singing, I’ve kept a little door open somewhere in the back of my heart. Sure enough, I don’t see myself singing in chamber choirs, oratorio choirs or project choirs, and I definitely don’t want to sing solo parts in front of large audiences any longer, but deep down I’ve remained convinced that singing is… Continue

Pipe model of a Kargyraa singer's vocal tract

The melody pitch f1 (the center frequency of the first formant) in Kargyraa voices is determined by the mouth opening. A perturbation method predicts the resonance shift caused by a bore enlargement at a position x0 of a pipe with a irregular geometry (e.g., Fletcher & Rossing 1991). During a performance of Kargyraa, the bore diameter of the vocal tract changes at the… Continue

False vocal fold surface waves during Sygyt singing: a theoretical study



Chen-Gia Tsai



1. Introduction



Overtone singing is a vocal technique found in Central Asian cultures such as Tuva and Mongolia, by which one singer produces a high pitch of nF0 along with a low drone pitch of F0 (F0 is the fundamental frequency, n = 6, 7, ...13 in typical performances). The voice of overtone singing is characterized by a sharp formant centered at nF0.…

Physical Modeling of the vocal tract of a Sygyt singer



Chen-Gia Tsai



Source theory v.s. Resonance theory



Two types of overtone-singing should be distinguished: Sygyt and Kargyraa. In Sygyt performances, the rising tongue divides the vocal tract into two cavities, which are connected by a narrow channel, whereas the tongue does not rise in Kargyraa performances.



Up until now, two major theories have been proposed on the production of the… Continue

Perception of Overtone Singing



Chen-Gia Tsai



Pitch strength



Voices of overtone-singing differ from normal voices in having a sharp formant Fk (k denotes Kh??mei), which elicits the melody pitch fk = nf0. For normal voices, the bandwidths of formants are always so large that the formants merely contribute to the perception of timbre. For overtone-singing voices, the sharp formant Fk can contribute to the perception of pitch.
