> But learning trombone, and then mapping that knowledge to a euphonium, trumpet, tuba, etc, gives you a knowledge about that instrument (eg ok if note X is 1st valve, and note X+1 is 1+2, then i know adding 2-to-1 adds a half step, because position 3 is a half step from position 4).

I don't think intervals are unique to trombones. If you understand that X+1 is a half step above X, and you know note X is 1st valve and note X+1 is 1+2, then you know adding 2-to-1 adds a half step even if you've never seen a trombone.

I guess, but the sequence of positions 6->5->4->3->2-1 maps to valves

- 1+3 (6)

- 2+3 (5)

- 1+2 (4)

- 1 (3)

- 2 (2)

- open (1)

All I mean to say, sliding a little bit at a time up the slide is easy to map to "short slide higher pitch" in a way that valves don't
