Liad,
the baroque/natural trumpet is almost as long as a trombone. Its bore being cylindrical and playing on the high partials is a completely different feeling. The fact that in the beginning playing resonantly centered (our goal with modern trumpets!!) means playing out of tune is disconcerting to all.
It takes a while to get our chops and brain sensitive to these differences. It is much easier when playing with an orchestra that doesn't play "well tempered"(on purpose..........
).
The best thing to do is get one and be aware that the first six months are difficult. It is worth the effort!
