Tenors need not tune their tracts because their pitch-to-formant ratio stays high

Evidence

This tuning-in/formant tuning effect is not something that tenors need to do since the ratio between the formant frequencies and the f0 of the tenor’s range is higher than that for sopranos. However, all singers who do not use amplification need to project above accompaniment, particularly when this is a full orchestra and Table 4. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1356

Categorization

• QUESTION: Trails off mid-sentence at the chapter cut — the full discussion of orchestra projection seems to continue beyond what’s quoted; not fully self-contained.
• corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1356
• XREF: connects to: Higher pitched notes spread harmonics so wide that formant peaks vanish; Tenors avoid formant tuning because their range leaves a higher f0-to-formant ratio. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1373
