Show 32 Figure 3. Spectrograph of overtone isolations. the "00" and "eehr" sounds. The images on the left are the "eehr" sound from audio example 12, whose isolated overtones are very bright. The second partial is also very strong and may be distracting while listening for the upper partials. The "007' sound from audio example 11 is on the right and conversely has a stronger fundamental and less interference from the second partial. While changing the shape of the lips and tongue allows certain overtones to "speak," it is the singer's 'Soft palate height, glottal height, and air flow pressure that control the volume and clarity of the overtones. Lowering the soft palate, raising the larynx, and providing maximum diaphragm support will bring out the isolated tones so that they as loud as the fundamental. Audio examples 13 and 14 demonstrate overtone singing with these additional modifications. The range in which overtones can be easily isolated is an acoustical phenomenon. The range of overtones for both Tuvan and Western singers and for both men and women is basically the same, and it lies within an octave and a half. Where the Lowest C on the piano is C 1, overtones speak most easily from AS to E7, with the most prominent and |
