[Trombone-l] Antique horns

[Ray Horton]

That's exactly what it is, Adrian, a system with individual valves and 
no combinations.  In theory, the horn plays in tune because there are no 
out-of-tune valve combinations. 

The theory breaks down, of course, because any brass instrument 
generally has more intonation problems between the different partials 
than it does in getting a single valve combination in tune.


Here is a much more extreme example of the same idea:

Try one of those at your next gig.
