Well, I’ve always been a good player, but after a masterclass and one lesson with Dave I went from struggling to hit two Cs above the staff to being able to play a nice triple F everyday. His breathing has changed things that no other teacher has been able to change. He really reminds me of what Arnold Jacobs would be if I would’ve been if I would’ve been around in his era. I’m a tuba player, but my lesson with Dave is still probably the most helpful I have EVER had. For reference I’ve had lesson/masterclass sessions with Warren Deck, Perantoni, Zerkel, and many other big names. He is absolutely wonderful, and the best part is a lot of his teachings are on YouTube! I highly recommend Dave and everything he has to offer.
