Samuel Hazo's "Arabesque"

[Estraven]

Hello all,

My local community band is working on "Arabesque" and the articulation needed for the triplet patterns that start in measure 58 is something I've never learned to do.

I think this is a good demonstration of the result, but somehow I need to get there:

I suspect that the Arban's sections on double and triple tongueing are where I need to start, can anyone offer additional advice?

Oh yes, I intend to seek "professional help" for this from the local trombone pro.

Thanks in advance.

<edit> Well, whadda ya know, moments after I write this I see this:
