[Trombone-l] Antique horns

[Ray Horton]

Hmm.  Your first theory  would seem easier to play, but backwards to 
every other valve system.  (Imagine trilling  A to Bb - hold down the 
second valve for A, adding the first raises it to Bb). Your second 
theory is a little more similar to modern valves but harder - really 
more like pushing a slide out with your fingers.


My head's exploding.
