Breathing and support are considered cornerstones of a secure vocal technique for classical singing. No area of vocal pedagogy has been more controversial and, despite recent advances in the understanding of how the respiratory system functions both in speech and song, some breath management strategies for singing continue to be at odds with scientific fact. Furthermore, many students find the development of these skills a challenge. Accent Method Breathing is a technique that is well grounded in science as it is based on the structure and function of the respiratory system. Accent Method was developed for the remediation of speech and voice difficulties but in the past 20 years it has also been used to help develop breathing and support in singers. The method has been used in both private singing studios and in institutions such as the Queensland Conservatorium Griffith University. Extant research in to Accent Method has focussed on its use in clinical populations and on its effects on the voices of normal speakers. Accent Method has never been evaluated specifically on singers though anecdotal evidence and clinical experience attest to its efficacy with this population. The current study aimed to evaluate the efficacy of Accent Method Breathing with students of classical singing in the early years of their training. A group of students underwent a 10 week group instruction in Accent Method with a matched group of students acting as controls. Measures were taken pre and post intervention consisting of Maximum Phonation Time (MPT), Mean Air Flow Rate through steady state vowels (MFR) and a Phonetogram. The students were also recorded singing a standard passage that was later judged by an expert panel.
