Hey gang! I love to watch trumpet YouTube videos. From straight up professionals to church amateurs it is always fun. The one thing I notice most often is the different preference for which finger is used to move the 3rd valve slide. Some hold the bottom of the valves and use their index finger or more commonly so their middle finger when holding it like that. On the other hand Wynton is now using his pinky to move the slide as his index finger is over top the bell.
I personally use my ring finger with my P3. The black elastic band/string Monette includes helps to bring it to slide back easily. I just have to get it the right length and I'm set. I'm not gonna lie, my LEAST favorite part of playing the trumpet, having to move that damn thing. I've had to get way better since switching to the heavier Monette.
Everyone's hand is made differently, so I thought it would be fun to ask, "What's your preference?"
