I've been playing trumpet for over 40 years. I've tried many mouthpieces by Bach, Schilke, and several others to achieve a bright, tight lead sound, but found difficulty playing the smaller rim, throat, etc.

Not so with the Ingram Lead Mouthpiece!

When I combine the "Yoga" breathing technique with an open aperture (from Roger's book, "Clinical Notes on Trumpet Playing"), this Ingram lead mouthpiece plays in the upper register with a wonderful sound, spectacular projection, and relative ease.

Thank you, Roger for sharing the specs on this mouthpiece with the world!!
