Analysis of Voice Parameters Variation during Passaggio of the Trained Male Singers

It's not easy to produce very high tones during singing for not only untrained ordinary people but also even trained singers. To get high singing tones from the low tones, some trained singers used to use a distinguished singing technique, Passaggio (vocal register transition). The purpose of this study is to compare several voice parameters variation between when to sing with using the passaggio technique and to sing without using it. We selected 18 male singers (tenor 8, baritone 10), who had more than 7 years of experience and were well trained in passaggio technique. Simultaneous measurements of fundamental frequency (F0), mean flow rate (MFR), intensity (I), and subglottal pressure (Psub) were performed using the phonatory function analyzer (Nagashima). For the tenor, target tones /a/ were presented: 1) easy phonation: $B_{2}$, 2) high tone without passaggio: F$#_{3}$ 3) high tone with passaggio: F$#_{3}$. For the baritone, target tones /a/ were presented: 1) easy phonation: G$#_{3}$, 2) high tone without passaggio: D$#_{3}$, 3) high tone with passaggio: D$#_{3}$. F0 of the target tones between non-passaggio group and passaggio group was almost the same in both tenor and baritone groups. Intensity of the non-passaggio and passaggio vocalization was much louder than that of easy phonation and pasaggio was louder than non-passaggio vocalization (especially statistically significant in baritone singers). MFR of the passaggio vocalization was greater than non-passaggio vocalization in both tenor and baritone group, but statistically significant only in baritone. Psub of the passaggio vocalization was greater than that of the non-passaggio vocalization in both tenor and baritone group, but statistically not significant in tenor.
