The Influence of Vocal Rehearsal on Acoustic Voice Characteristics of Professional Female Singers

Phonation in professional singers is somewhat athletic. It requires not only good vocal technique, but voice health as well. Both can be established by regular vocal practice. Warm-up & vocal exercises are important activities that need to be practiced regularly & with discipline if they are to build the mental & physical efficacy that is needed for vocal performance & a successful career in singing. The positive effects of warm-up exercises on the voice are well known, as are the possible negative post-performance effects, which are acute & soon disappear in well-trained singers. But what about vocal rehearsal & its acoustic effects? The present study attempts to give an answer to this question. The investigation included seven professional female singers. Their voices were acoustically analyzed before & after one hour of vocal rehearsal. The results suggested changes in the direction of optimization. 2 Tables, 3 Figures, 21 References.
