DIVERSE RESONANCE TUNING STRATEGIES FOR WOMEN SINGERS

lab.grenoble-inp.fr Over a range from 200 to 2000 Hz, the fundamental fre-quency f0 of women's singing voices covers the range of the first two resonances (R1 and R2) of the vocal tract. This allows diverse techniques of resonance tuning. Res-onances were measured using broadband excitation at their lips. A commonly noted strategy, used by sopranos, and some altos, is to tune R1 close to the fundamental frequency f0 (R1: f0 tuning) once f0 approached the value of R1 of that vowel in speech. At extremely high pitch, sopranos could no longer increase R1 sufficiently and switched from R1: f0 to R2: f0 tuning. At lower pitch many singers of various singing styles found it advanta-geous to use R1:2 f0 tuning Additionally, many sopranos employed R2:2 f0 tuning over some of their range, often simultaneously with R1: f0 tuning. 1
