Estill Voice Training is an approach to voice training that merges science and art. It separates training into three areas of proficiency: Craft, Artistry and Magic and develops vocal expertise as an athletic discipline, integrating the results of current voice research with voice training. The system is useful and practical for all voices, abilities and genres. It is free of aesthetic bias, meaning any non-abusive voice quality is accepted and nurtured, embracing cultural and musical diversity.
