This is a simplified physical model proposed by me for the larynx during VVM phonation mode, which produces similar sounds to those from the Tibetan Chant tradition. Below, the vocal folds (m1,m2) and above, the false or ventricular folds (m3). In this example, vocal folds oscillate at a frequency which is twice as that of the ventricular folds. The letters m stand for mass, k for stiffness, and r for damping coefficient. Indexes r-l stand for left and right sides, respectively. |
During my research work in music acoustics I created/recorded/processed some gigabytes of sound files, most of them of no musical interest for the listener. FILES IN REAL AUDIO FORMAT Vocal-ventricular sounds (used in Tibetan and Mongolian “undertone” singing): 1.Fixed fundamental and sweeping overtones 4. Popeye the Saylor used VVM !! (an original recording from a William Costello’s version) Periodic pulse register , see Paper VI Vocal Growl (co-oscillation of vocal folds and epiglottis)-similar to the mechanism used by Louis Armstrong 9. Periodic Growl, in f0/2 and fo/3, with overtone singing Tarogato (wooden saxophone from Hungary) A piece for OBOE called “My Six Marigaux 10499’s”, recorded in 6 channels All recordings, excepted by numbers 0 (Gyuto Monks, Tibet) and 4 (Popeye, W. Costello) are performed by Leonardo Fuks |
