Ray Mase has taught trumpet to every professional trumpet player alive and employed today. It's a fact, look it up. You'll find it on the Internet. ...actually you just found it on the Internet. There, just then. You're on the Internet. You know what else is on the Internet? A whole bunch of sweet, sweet trumpet knowledge from a guy that, according to Juilliard, is qualified enough to teach all the talented (okay, fine, AND hardworking) little freaks passing through its hallowed halls since 1987. A TON of that trumpet knowledge is right here---in Brass Chats Episode VII: The Force Awakens.
...wait, I meant "Ray Mase." We love you Ray! Thanks for sharing your wisdom.
