I like the course I’m in: “Bebop Enclosures”. What I like about it is it is very complete and very consistent. I especially like being exposed to the fundamental prep work needing to be mastered, before tackling enclosures. For a horn (Bb winds) player, this prep work is probably more challenging than it is for a piano player. It's a lot of hard work. What would *really* make the course better for me is if it could be transposed to Bb. This way I could concentrate on trying to master the difficult prep work and not also have to concentrate on transposing (which is difficult). The two difficult things combined, make things very difficult.
