Mr Keller is very smart and does very well communicating his knowledge to others. As long as you take his classes somewhat seriously, you will have no problem of him getting angry at you. However, if you show any signs of disrespect or don't care about the class be prepared to get roasted. Kellers lessons extend much farther than just band and can be applied to any aspect of life. Keller is also a very traditional man/teacher and has gentlemanly values. Act like a gentleman and he will like you!

Mr. Keller is one of my favorite teachers. He makes most classes fun, but is very into band and expects his students to be the same way. He teaches you a lot, but when he's in a bad mood will be very mean. I would recommend this teacher.

Clearly knowledgeable but has blatant favorites. If you aren't one of them, you will get in trouble for doing the slightest thing. If you are, you'll always get away with anything but be careful because he's mercurial about them.

Very great band director and by far the most influential teacher I've ever had. Very knowledgable on not only music, but also life in general. Mr. Keller is a very inspiring teacher and always goes out of his way to make things a learning opportunity for the students. Overall, he's very responsible and I have a great respect for Mr. Keller. I could not appreciate him any more as my teacher/mentor and reccomend him to anybody.

He's a great band teacher. He knows a lot about music and not just music, even life. You learn much more than just about music in his class. However, his exams aren't that easy. And there are always

Good teacher but expects every student to have a band-centred life. Exams are harder than a lot of academic exams, and he has serious mood swings.

Keller is one of the best teachers. Ever. There's no way around that. He teaches his students so much about life, and is really inspiring.

If you can't understand K-Dawg's analogies, then there's no helping you. And if they don't make you laugh, then you have a problem.

One of the best teachers I've ever had (including college). I learned more from him than I could even tell you - about music, learning, and life. Don't take him for granted.

Great teacher, if you don't like him, that's because you talked and otherwise misbehaved even more than I did. -AC
