The IVA technique is based on 17th and 18th Century principles of singing developed by the Schola Cantorum. Our goal is to train voices to sing in a free and natural manner, smoothly, from the bottom of the range to the top with no breaks or sudden changes in quality. Training in this technique gives the singer access to all dynamics, with tonal clarity and flexibility. Also, training in this technique helps improve a singer’s range, endurance, stamina, breath control, resonance, vocal strength and vocal quality across all styles of music without fatigue or damage to the voice. We accomplish these results by training the singer to find a balance between airflow and intrinsic muscular resistance, all within a resting laryngeal posture.
