YES - That was wonderful!!! Thank you Luther College Trombone Choir and Dr. Yates for that exciting performance of Tsunami! Very effective stylistically and dynamically. Of course, big time kudos to Mitchell McManus for the air-raid siren!! This effect just makes the music so impactful. Congrats on a great job - I truly enjoyed the performance.
Thanks for the video - great information to have. I had a Bach 50 B (dependent rotor) converted to independent rotor about 10 plus years ago and thought the second valve was in G. I'll try to tune it for Gb - that might work better. My favorite notes to play with the valves are with the first valve - C in the bass clef staff, Bb in a short 4th position, and F below the staff with the second valve in a short fourth position.
