In general, I agree with what Greg is trying to teach, but that doesn’t mean it’s actually what is happening. In the video I posted, the person demonstrated that the player in the recording would sometimes have the same shape for two different pitches, depending on the volume. A low/quiet note could have the same shape as a high/loud note.
This is a bit like picking fly shit out of pepper, as I understand the crux of Greg’s teaching to be that he believes most players that are seeking out playing help are likely overblowing and not utilizing shape properly – this was certainly the case for me.
I’d love to hear what Greg has to say on this when he has time. Sounds like a great conversation for the next Zoom call! 🙂
