I've thought about it enough to get stressed out. I had to stop this morning and remind myself that there is no wrong answer.
I can go get a nice trombone. I can learn to play again - it won't take nearly as long as it did the first time. I already know what to do. It's no different than working out. It's just a matter of execution. I will never be great. But I will quickly be good. Good enough is not possible in artistic endeavors, so good will have to do.
I can hear the loud pop, let reason take over and not get a new horn. For a lot less money, I can buy some good albums and listen attentively to the great, legendary trombonists. I already have a few. Arthur Pryor (circa 1905) recorded a version of "Blue Bells of Scotland" that nobody today can even touch. And when he recorded it, there was not way to copy the recordings, so he made 40 recordings a day by playing the piece 4 times in front of ten individual recording devices. I don't have to play a trombone to respect those who do it well. I can enjoy Arthur Pryor and a hundred others whenever I want to without spending a ton of money or practicing.
Logic votes for the second answer. Plus, getting a trombone means making a commitment to it. It takes an hour a day, every day, to do it well. Logically and financially, getting another trombone makes no sense at all. It's not like I don't have other things to do with both my time and money just now.
But, of course, logic and artistic ventures are incompatible by definition, so who gives two shakes of a fat rat's ass what logic says?
Should I get one? Which one? Will I do what I need to do to play well (I won't be able to tolerate playing badly). Should I wait and see if prices come down or if the passion subsides? Should I refocus on the piano and guitar I already have? Should I be logical and responsible? Should I go for it and enjoy it? Should I just think about it summore?
The answer is a resounding, "Yes!". But what is the question again?
