"Gary Radtke is a brilliant, articulate and interesting person. He is a musician and technician, designer of machinery and a trumpeter with an extremely broad knowledge base. His lectures are informative, interesting and humorous as well as captivating. He really personifies his motto ‘we do the math, you make the music”.

Ronald Romm and Dr. Michael Ewald

"Gary Radtke is one of the world's foremost authorities on designing and manufacturing trumpet mouthpieces. A GR clinic explains, with no mystery or obfuscation, why a mouthpiece works or it doesn't. With his subtle humor and low-key delivery, Gary makes the incomprehensible seem simple (well...kind of simple.)"

The Conscious Trumpeter

Gary Radtke has developed an exciting new seminar based on his "Conscious Embouchure" Method. The Conscious Embouchure was developed by GR in order to have the player bring subconscious playing to the conscious level. This new approach is revolutionary to brass pedagogy and is amazingly effective in improving all aspects of brass playing. Get ready for this new (brain) wave in trumpet playing!

The Scientific Approach to Brass Playing

This informative and entertaining clinic deals with the science behind the sound of a brass instrument and what makes the system work.

Students will discover just what is happening in the body and instrument when sound is produced.

This is a very eye opening lecture which will put to rest many rumours and "voodoo" to which brass players often fall victim.

The Scientific Approach to Selecting the Proper Equipment

This clinic deals with the science behind the mouthpiece and trumpet and how to use a systematic approach to proper equipment selection.

This clinic is complete with information and demonstrations on how to use the GR Playing Tests to insure a proper match between player, mouthpiece, and instrument.

This clinic is a "must see" for players who are on the endless "Mouthpiece Safari", as well as players who are somewhat happy with their equipment.

Do you want to find out how to properly choose your equipment without the usual guesswork? Experience GR's revolutionary way of thinking and his foolproof method of proper equipment selection.

Understanding The Mouthpiece

This clinic explores all aspects of trumpet mouthpiece design and encourages a thorough understanding of mouthpiece parameters and how they affect brass instrument sound and response. This lecture is ideal for brass instrumentalists who are looking for optimum performance from their mouthpiece.
