Sets for Marching ??? Explain to me ... or are you referring to choreographed moves for the half-time show? Unless you are dead, you learn from everyone, musician or not. Names and education don't impress me, actions do! Whenever I look at the listing of those that were awarded the Congressional Medal of Honor, I've yet to see one that had earned a Doctorate in other than Medicine when it was awarded. Too, when I've looked at the listing on War Memorials or walked about in a military cemetery I think of no correlation to the education or vocational attainment of the deceased. Don't get me wrong, I know who Thomas Hooten is and he is really a fine trumpet player and he may be a great teacher, the latter I can't personally say as he has not taught me. Too, he ought to be able to play Sousa marches as good as I can, if not better. A march for a musician is a genre of music to which one can move in certain proscribed steps at a cadence / tempo, as otherwise it is just choreographed sequential moves / a dance perhaps. Do not misunderstand me, I know Thomas Hooten is a fine trumpet player, but I cannot critique him as a teacher because he hasn't taught me. However, I do expect him to be able to play Sousa marches as good as me, if not better on the trumpet part but I don't know if he could play the C piccolo part on a Bb piccolo trumpet, or the French horn part on a Mellophone, and the bass parts of The Stars and Stripes, Forever! which I can and have, and have been longer than he has been alive.
