Abstract

SummaryPrevious studies suggest that singers modify articulation to avoid that the pitch frequency F0 exceeds the normal value of the first formant F1Normal. Using magnetic resonance imaging at a rate of 5 frames/s, articulation was analyzed in a professional soprano singing an ascending triad pattern from C4 to G5 (262–784 Hz) on the vowels /i, e, u, o, a/. Lip and jaw opening and tongue dorsum height were measured and analyzed as function of pitch. Four or five semitones below the pitch where F0 = F1Normal the tongue dorsum height was reduced in /i, e, u, a/, whereas in /o/ the lip opening was widened and in /a/ also the jaw opening was widened. At higher pitches, the jaw opening was widened in all vowels. These articulatory maneuvers are likely to raise F1 in these vowels.
