Effectiveness of using the resonant vocal techniques in singing voice disorders

Singing voice disorders are an important segment of vocal pathology, targeting a niche of professional and amateur singers of all musical genres. The aim of this study is to evaluate the effectiveness of using the principles of vocal hygiene and the eclectic vocal therapy model by combining three resonant vocal techniques: humming, the method of disguised yawning and the chewing technique, in the corrective-recuperative vocal therapy program. The positive effects of the vocal therapy used in all five case studies were observed. If the initial assessment relates to altered vocal parameters, pain in the laryngeal muscles and a negative influence of vocal problems on quality of life, the final assessment found normalization of vocal parameters, decreased pain and improved the quality of life.
