Thank you, Scott. I play both diatonic and chromatic. The difference: The chromatic has one more octave than the diatonic. I can play 38 notes on my diatonic, all completely accurately. You use OBs while I use prepared (valved) instruments most of the time. Apart from the missing octave, I prefer the diatonic. The reason: Chromatics are big instruments with big reeds and their own sound. My embouchure allows me to personalize the sounds I get out of my diatonic. Much more expressive."Problem: over blowing even for those that claim the ability is not stable, therefore not a plausible method, for accurately over coming the instruments stubby scales."
This is absolutely, positively untrue. An overblow is no more "unstable" than a regular "blues" bend or countless types of notes played on a saxophone, trumpet etc.
