This thesis examines the concept of the true voice as a method for the exploration of identity. A revised Delphi approach was used to facilitate the open discussion of this concept amongst a group of specialists from various areas of voicework and singing. The primary objective of the study was to provide a framework of understanding from which to view a holistic approach to vocal development, with particular relevance to the singing voice, as well as lay the foundations for further study in this area through presenting a range of opinions on the true voice. The study gave definition to the concept of the true voice and revealed that it could be used as both a framework of understanding as well as an application to voicework.
