I started in the third grade. My parents immediately signed me up for lessons with the music teacher's recommended trumpet teacher. He definitely helped me a lot in the beginning excel over the other students and get the very basics down. 7 years later, now, and I'm still with him. He's a good player and a good teacher, but I feel like he isn't properly helping me with a few of my fundamental playing issues. I talk to him a lot about addressing my stagnant range development, and I really don't think he knows what he's talking about. He's great for 10 year olds but I once I got to high school I needed someone who could really assist me in advancing my playing...honestly right now I think it's mostly my practicing that's helping - he's making a very little impact on my playing. The problem is just that we have a great relationship and telling him I'm going to study with someone else is unthinkable to me. There's a teacher in my city who's known as the trumpet guy. I had one lesson with him and he seemed very good and masterful. His students are very good. Have any of you had to go through quitting a teacher you've been with for so long and gotten attached to?
