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. Read more here: http://www.bolvinmusic.com/publications5.html 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. Thanks!!
