Does a Systematic Vocal Exercise Program Enhance the Physiologic Range of Voice Production in Classical Singing Graduate-Level Students?

Abstract

Purpose The purpose of this study was to assess the effects of vocal function exercises (VFEs) on the physiologic range of the operatic voice. The primary outcome measure was total voice range profile (VRP) area. Method Forty graduate-level opera majors were randomly assigned to experimental (training with VFE + vocal hygiene) and control (vocal hygiene only) groups. All participants underwent an acoustic voice assessment (modified VRP) pre and post 10 weeks of the assigned intervention. VRP total area was calculated and compared between and within the two groups. The total VRP area was subsequently divided into three area thirds (low, medium, and high). Results A significant improvement (increase) was observed in the VFE group for the primary outcome measure of VRP area when pre- and postvoice conditions were compared for total area, upper third, and middle third. No significant improvement was found in the vocal hygiene–only group. Conclusion Vocal training with VFEs over a 10-week period demonstrated positive effects on physiologic voice range as evidenced by an increase in the total VRP area and therefore may enhance the potential of those who already have professional voice training.

Optimization of Vocal Singing Training Methods Based on Multimedia Data Analysis

“…anks to the binary representation, so retrieval can be performed quickly by efficient operations between hash codes, and the storage cost can be greatly reduced, so hashing methods have gained a lot of attention. Early hashing methods mainly focus on similarity retrieval tasks in single-modal data scenarios (i.e., unimodal hashing methods) [17]. Unimodal hashing methods can be classified according to the way the hash function is generated: dataindependent methods and data-dependent methods.…”

Development of vocal exercises for training musical skills (Desarrollo de ejercicios vocales para entrenar las habilidades musicales)

“…The voice creates a clear and bright sound, with a pure approximation of resonance that will sound great and project easily. It was essential to sing the traditional ‘m-m-m’ up and down the vocal range, from low to medium, then to high and back again (Guzman et al, 2020). (2.2) Vocal flexibility and coordination.…”

“…Loudly, but without shouting, it is necessary to sing from the sounds that are derived from an associative series of pictures with animals or natural phenomena. Starting in the middle range, it was necessary to perform different sounds, high or low, dropping the vocal range several times, starting higher or lower each time (Guzman et al, 2020). Various paintings were used in this exercise, such as Henri Rousseau’s Tiger in the Tropical Storm or John William Waterhouse’s Ulysses and the Sirens . (3) Even rhythm practice.…”

“…La voz crea un sonido claro y luminoso, con una aproximación pura de resonancia que sonará bien y se proyectará fácilmente. Era esencial emitir el tradicional ‘m-m-m’ por todo el rango vocal, de bajo a medio y después al rango alto y vuelta a empezar (Guzman et al, 2020). (2.2) Flexibilidad y coordinación vocal.…”

Variabilidad de micrófonos utilizados para análisis acústico de la voz en los últimos veinte años

“…Guzmán et al indican que "Una interfaz KayPENTAX CSL y un micrófono unidireccional SHURE (modelo SM-48) fueron utilizados para capturar las señales de audio" [24]. El micrófono SHURE SM-48 es dinámico cardioide, con una respuesta de frecuencias no plana, fabricado para uso artístico o de megafonía.…”
