Classical singers use nasal consonants as ‘resonance exercises’, and aim at vibratory sensations at the nose and facial structures. This study investigates the effects of nasality at the wide region of fundamental phonation frequency variation in singing. The vocal tract reactance computed in the frequency range 0-1.5 kHz for vowels [a:] and [i:] without and with nasality showed that the lowest resonance frequency clearly increased, and the reactance decreased throughout the range compared to non-nasalized phonation. Thus, some nasality may offer assistance for phonation.
