Oddly enough, I was listening to a trumpet piece on our local classical station this morning, and the program director prefaced it by a brief monologue about playing trumpet. I obviously don't remember it verbatim, but I'll give you my very rough paraphrase from memory. Ahem!
Brass instruments in general, and the trumpet in particular, are difficult to play well, and impossible to master. It takes a lifetime of dedicated practice to play the trumpet. Trumpet great Dizzy Gillespie once said, "Some days you get up and put the trumpet to your chops and it sounds pretty good and you win. Some days you try and nothing works, and the trumpet wins. This goes on and on and then you die and the trumpet wins." All those hours of dedicated practice are to minimize the damage on days the trumpet wins.
For me, it's a labor of love, and I never get tired of it. Just know what you're getting into ahead of time. I've often wondered if I should switch to a guitar or piano that might offer the ability to play in a relaxed environment for family and friends without so much practice on a daily basis, and also with less struggle to find practicing venues. But I can't. I love the trumpet. I love playing the trumpet.
On the days when everything just flows, it's an awesome feeling, and even something of an emotional rush, and I know I'm one of a small group of specialists - heck, I know untold dozens of piano and guitar players. Everybody plays piano and guitar. My dad hasn't played guitar in 25 years, but he can still pick it up and do something musical and entertaining on a moment's notice. A good trumpeter is something special (my opinion).
Yeah, it's hard, but I'm all in.
