I have been playing trumpet for about 14 years now. I take lessons. I have a decent upper range. As in E above the staff very consistant and can play on cue. F and G on good days. But to my question. I have been reading posts and it seems like everybody here plays Double C or Super C as I like to call it. Even beginners or come back players after a 30 year break. What's the deal. I just don't get it. My instructor can as that is understandable he is a very seasoned player and does it for a living. Just curious to see if they are just blowing smoke. Your thoughts?
