Breath Support
Quick Definition
The coordinated management of respiratory muscles to provide controlled airflow and appropriate subglottal pressure for singing.
Factual Definition
The regulation of subglottal pressure through coordinated antagonistic action of inspiratory muscles (primarily diaphragm, external intercostals) and expiratory muscles (abdominals, internal intercostals) to maintain steady airflow appropriate to the phonatory demands of the musical phrase (Sundberg, 1987; Titze, 1994).
