GR Technologies has carefully defined the mouthpiece with mathematical parameters. With this progressive thinking comes a new tool for mouthpiece design. With this new paradigm in brass instrument technology and development comes change. Now that we have lines, arcs, points, and angles to describe the mouthpiece we will not be using the same terminology as other makers.

GR Mouthpieces are designed using our own Design Program.  This program is unique to GR Technologies and was developed by Gary Radtke and Chuck Macaluso. 

This program ensures that every mouthpiece designed by GR solves the Sound Wave Equation.  This means that the sound wave is taken into account in the design of every GR Mouthpiece.  By solving the Sound Wave Equation, the sound wave travels through the mouthpiece and  reflects back from the bell without any interruptions what so ever.   This is accomplished by removing all Discontinuities from the design.
