Here is all you need to know about the Stratos Device…
The Stratos Embouchure Training System, Stratos Performer, is a precisely adjustable attachment for all brass instruments. Designed to reduce mouthpiece pressure and optimise your jaw position and so improve your embouchure
This high-quality embouchure system is simply attached to your instrument or mouthpiece whilst you play or practice. STRATOS Performer reduces mouthpiece pressure and ensures a good jaw position taking away the need to “think” about position and pressure. Practising with STRATOS Performer re-educates your muscles and nerves and allows you to adopt your improved embouchure position naturally, even after you remove it from your instrument. This allows you to concentrate on other aspects of your playing, and you can relax back into better and better performances. STRATOS Performer has been shown to help solve many embouchure problems. It also gives improvements in power, range, tone, and stamina allowing you to play with more ease and greater flexibility.
