"I play on a GR 67L and the sound is simply too bright. What do you suggest?"

Scriver's reply:

My first question is would this be a perceived sound by you, or have you recorded your sound and had friends out in front of the horn tell you that the sound is too bright?

Here is why I ask. The sound that we "hear" or perceive is mostly sound that is vibrating through our skull. Yes, some is ambient sound from the bell of the trumpet, but most of the sound that we hear is through the flesh and bone in our skull.

Have you ever heard your voice on a tape? It doesn't sound like you. That is due to the fact that the perceived sound or vibrations in our skull, is different from the actual sound. We are hearing the overtones in our voice differently!

GR Mouthpieces produce more overtones than conventional mouthpieces. More higher overtones, and more lower overtones. The higher overtones are more easily "heard" as vibrations in our skull than the lower overtones. We think that the sound is bright. Record yourself or ask some friends to listen out in front of the horn and you will see that your sound is actually fatter and more full than with conventional mouthpieces.
