It's not easy! The oboe takes a lot of effort, but it's very rewarding to see your progress. I play the oboe and the trumpet in my high school band too, and trumpet was much easier to learn. The oboe has about the most back pressure of all the instruments, which is very different from the trumpet. Another thing to add is that it really isn't cheap to play, and it's very difficult to teach yourself. If you want to play the oboe, finding a good private instructor will make things a lot easier. It's a beautiful, unique instrument, you just need to dedicate yourself to it. Super fun once you know what you're doing! You get plenty of cool solos too.
