The Trombone is an extremely fun instrument to play, and MusicProfessor's intermediate curriculum will help you get the most out of your learning. Pick up where our Beginner Trombone course leaves off, adding more complex rhythms, scales and tone exercises to your repertoire. On the way, you'll also learn useful advanced music theory and musicianship skills.
Too much time is spent on how the notes are written and where you can find them on the slide. I would have expected to get more advice about technique - breathing technique, lips, how a good tone should sound, etc.
