@rowuk Thanks for the input. I just got a new computer and it has no sound input built in. I am waiting on a Focusrite 2i2. When it gets here I'll do some recording. Listening to yourself is for sure a good way to judge progress and plot ways to improve. I am also anxious to listen to my improv. I've been working on it and I think maybe I don't totally suck anymore.
I play in a couple of big bands, a couple of small jazz quintets, and a couple of horn band rock groups. It sounds like a lot more than it really is. With all that combined I'm actually working one or two gigs a month when we aren't in the pandemic. The Balanced Embouchure workout has made C up to Eb feel like middle range. When I get the Focusrite in I'll record some of the horn band stuff and see what the high notes sound like. I am hopeful.
