Trent,
I do have some tips:
1) forget the idea that the baroque trumpet has anything to do with what you now understand as "trumpet". It will also change your definition of trumpet once that you get comfortable!
2) It took me about 6 months before I started to get comfortable and 18 months until my audiences did.
3) I bought a Münkwitz three hole baroque trumpet with D, Db, C and Cb bows (you replace the back part of the trumpet for the various keys) and have just ordered a Bb bow that I need when playing Haydn for instance. It cost less than $2000 for everything. It really works for me. I think Barry Baugess sells them in the states - or you can order directly:
www.trumpetmaker.com * Historical brass instruments * Michael Münkwitz
Michael also has baroque trumpet building courses with Robert Barclay (CAN) and
Richard Seraphinoff
4) although not absolutely necessary, I did try a bunch of baroque mouthpieces and have to say that they make it MUCH easier to trill and tune. I now play a Klier 4C baroque mouthpiece with a very sharp rim.
5) the first six months I only used one hole for F and A. The other two I left closed and have added in the mean time when I play with groups using "modern" tempered scales.
6) like with any other instrument, you start with long tones, slurs and scales. You don't need any different books in the beginning, after a while you will want the books from Ed Tarr, Paul Plunkett and a couple of others.
7) This is the first step of becoming a well rounded trumpeter (I think it should be required for ANYBODY studying trumpet - even jazz!)
Congratulations on an excellent decision!
PM me if I can help further!
