A sort of homecoming

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

TSAI Chen-Gia : False vocal fold surface waves during Sygyt singing: a theoretical study

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… Continue

TSAI Chen-Gia: Physical Modeling of the vocal tract of a Sygyt singer

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

TSAI Chen-Gia : Perception of Overtone Singing

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.



A pitch model… Continue
