Note: Analysis of Native American Pueblo singing (male chorus with percussion). Micro-tonal variation gives effect of vibrato but is not a regular half- or whole-tone alternation of pitch| rather intentional part of the melody. New terms are needed for non-Western embellishments. "Roughness" defined as abundance of "harsh" glottal attacks. Irregular vibrations (noise) versus regular vibrations (harmony). Possible parameters: abrupt energetic (glottal) attack versus relaxed (breathy) attack. Rasp (constriction) versus breathiness (lack of tension in of vocal chords, which don?t vibrate together). These reflect emotional attitude| focus, or lack of focus. Samples of mid-Western American breathy vocalizing and Australian aborigine, rasp used as part of vocal style.
