Visualizers have been used successfully as a diagnostic tool by brass teachers since the 1920's. Our approach with the ATV goes far beyond visual diagnostics, providing an advanced, high-intensity Isotonic workout and low-intensity exercises to develop a relaxed aperture for greatly improved tone in the lower and middle registers.
See full instructions for use.
NOTE: CANNOT be used with a regular top for playing - ONLY WORKS WITH THE ATV
