Air Flow Warmup
I use this warmup to get a sense of my range and to reconnect to my air flow between the low to high registers. This is a trombone-specific warm up. I heard it played one time and have been using it ever since - please let me know if you know who came up with this. The goal is to be able to play everything smooth and connected, with a steady embouchure and lots of air support.
