What's the end goal? This is a VERY important decision. You need to be thinking about jobs in 4 years. What job would you like to do? This is the most important factor in your choice IMHO. If you can't see yourself being good enough to make a living playing trumpet, music performance may not be your calling. I know LOTS of guys with performance degrees that are trying desperately to find jobs in the music field. A lot of them wind up going back to school for something else, or just being content to work at a music store for 10 bucks an hour. Not a bad thing by any means, liking your job is more important than money IMO, but it's something to think about. If your going to teach, just be educated about the market where your planning to work and be realistic in your expectations. Music education is a great field!
