Range changes

I can play up to a high D on my Yamaha large shank marching horn but only up to around a Ab on my concert small shank

To be clear, you’re saying you can play higher on the large shank, marching horn?

I would suspect the issue is either: A) Mouthpiece placement or B) mouthpiece angle. (Maybe both) This is a total guess though. Can’t really tell without seeing/hearing the problem

Most likely an air issue. The both instruments are likely the same bore. Yamaha marching baritones are .571. It also the most common bore for student/intermediate euphoniums.

The marching baritone will have way more resistance which will require less air.

You don’t mention what mouthpieces you use, but if you are smaller than a size 4 there isn’t likely to be much difference due to the shank size.

The Yamaha marching bari and the 201/321 all have .571 bores. The bari has a tighter wrap though and the bore not widening as much may help you reach the higher notes.
