This sounds like a great routine, ZW. Thanks for sharing. I like how you focus on chops, good air and tongue rather than just one thing. I think a lot of routines tend to ignore one or other area, usually the tongue, and focus too much on air or flexibilities.
I will try this today. I haven’t experimented much with note bends. But I did notice in practice recently that keeping the air moving through the aperture without increasing the amount of air (so not spreading the aperture, just increasing the air velocity) really helps in the upper register.
