Okay, so here’s my update after one year. I have become super aware of how much tension I’ve been using, and I improved my sound and endurance slightly, which is always a good thing.

However I’ve been unable to reap any benefits from the new setting or improved range at all.

I can’t seem to transfer any of the ahh-oooh to my regular set up and the aaah-ooh setting is still super weak and useless as a normal embouchure.

I’m still doing the exercises around 15-30 mins per day. My point of difference on both embouchures is stuck around third space C to E slurs.

Still plugging away. Just curious what everyone else’s journey has been like.
