[Trombone-l] Antique horns

[David Leep]

Thanks for the appreciation, Ray.

I now see that my proposed explanation assumes that the valves, when
disengaged, favor the straight-through path as usual nowadays.  Since I
can't see inside them and don't know the history, there may be another
possibility -- what if the default position of the valves favors the side
ports instead?  Then no-valves-down would yield the shortest path after all
(via the first-valve crook), and pressing valves would generate positions 2
through 7 as Adrian said, except that you would have to press not only the
farthest valve you wanted but also hold down all lower-numbered ones as
well.  (I don't know whether such a fingering scheme would be practical.
Would it be more like woodwinds?  Other websites attribute similar-looking
six-valve trombones to Adolphe Sax.  Hmmm....)

Does anyone know which of these two interpretations of the valve action is
correct?
