Seiji ADACHI & Masashi YAMADA : An acoustical study of sound production in biphonic singing, Xöömij


Seiji ADACHI & Masashi YAMADA : An acoustical study of sound production in biphonic singing, Xöömij

Abstract A theory that the high melody pitch of biphonic singing, Xöömij, is produced by the pipe resonance of the rear cavity in the vocal tract is proposed. The front cavity resonance is not critical to the production of the melody pitch. This theory is derived from acoustic investigations on several three-dimensional shapes of a Xöömij singer’s vocal tract measured by magnetic resonance imaging. Four different shapes of the vocal tract are examined, with which the melody pitches of F6, G6, A6, and C7 are sung, along with the F3 drone of a specific pressed voice. The second formant frequency calculated from each tract shape is close to the melody pitch within an error of 36 cents. Sounds are synthesized by convolving a glottal source waveform provided by the Rosenberg model with transfer functions calculated from the vocal tract shapes. Two pitches are found to be successfully perceived when the synthesized sounds are listened to. In a frequency range below 2 kHz, their spectra have a strong resemblance to those of the sounds actually sung. The synthesized sounds, however, fail to replicate the harmonic clustering at 4–5 kHz observed in the actual sounds. This is speculated to originate from the glottal source specific to the “pressed” timbre of the drone.

Here we do our best to explain the method for throat-singing. You’ll find that basic throat-singing can be mastered surprisingly easily. So have a go!
To improve your throat-singing, vocalization and mouth-shaping should be mastered through trial and error. It’s a bit like learning to ride a bicycle (success only comes after many falls, right?)
Go for it, Dude/Babe, Boys ‘n’ Girls! Be ambitious! You’ll soon be a throat-singer!

STEP 0: Introduction

There are two important things you must master to be able to throat-sing: Firstly, the correct shape of your mouth, including your tongue and lips. Secondly, vocalization. You can master elementary throat-singing just by following the directions given in the seven steps below.
For each step, the method is written based on my personal technique, so I hope you find them useful as a guide until you find the technique which best suits you.
Here we go…

STEP 1: The shape of the mouth
STEP 2: The location of the tip of the tongue
STEP 3: The mouth as a resonator
STEP 4: A small vent-hole
STEP 5: The volume of the resonator
STEP 6: Vocalization
STEP 7: Hints and tips

More Throat-Singing Instructions

Allow me to introduce another WWW description of throat-singing technique by Dan Bennett.

Special thanks to Dan. He translated all of these instructions!
