I know I posted here, but I can no longer find the post.

I'm happy to announce the release of
The Arban Manual
A 69 lesson course that takes you step-by-step through the entire Arban method.
For all brass instruments.

I am also looking for info on all published versions of Arban. So far I am aware of the Fischer, Leduc and a German version.
If you know of others, please post here.
