Summary
Vocal warmup is generally accepted as vital for singing performance. However, only
a limited number of studies have evaluated this effect quantitatively. In this study,
we evaluated the effect of vocal warmup on voice production, among young female singers,
using a set of acoustic parameters. Warmup reduced frequency-perturbation (p < 0.001) and amplitude-perturbation values (p < 0.05). In addition, warmup increased singer's formant amplitude (p < 0.05) and improved noise-to-harmonic ratio (p < 0.05). Tone-matching accuracy, however, was not affected by warmup. The effect
of vocal warmup on frequency-perturbation parameters was more evident among mezzo-soprano
singers than it was among soprano singers. It was also more evident in the low pitch-range
than in the higher pitch-ranges (p < 0.05). The results of this study provide valid support for the advantageous effect
of vocal warmup on voice quality and present acoustic analysis as a valuable and sensitive
tool for quantifying this effect.
