If you're serious about getting better at your instrument, you need to take private lessons, whether it's with me or somebody else. A mentor who's invested in your growth is one of the biggest, most important parts of your game plan to play the best that you possibly can.
With me, lessons are an hour long, $75 an hour, one lesson a week, and you pay one month at a time. Lessons happen in Pasadena, near the intersection of the 210 and 134 freeways, or in the comfort of your home, over Skype. I teach trombone, bass trombone, baritone, and tuba, at all levels.
Sometimes beginners ask about half-hour lessons. I don't do half hour lessons, and I don't recommend you go looking for them. Beginners need more guidance, not less. Some people claim "young students can't concentrate longer than a half an hour, anyway". I take that to be a comment about the teacher, not the student. People have as much attention as they want to have, regardless of age.
