Warburton Trumpet A.T.V. - Advanced Training Visualizer Top


Visualizers have been used successfully as a diagnostic tool by brass teachers since the 1920's. Our approach with the A.T.V. 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.


What size A.T.V. do you need ?

If you already play a Warburton mouthpiece, all the A.T.V. rim diameters are the same as our regular mouthpieces. For example, if you play a Warburton 4SV you would want the size 4 A.T.V.

If you play another manufacturer's mouthpiece, our trumpet mouthpiece comparison chart may be able to help you find the Warburton size that matches your mouthpiece. For example, if you play a Schilke 15 you should order the size 3 A.T.V.


NOTE: You may use the Warburton trumpet/cornet backbore you aleady own
