I think they really hate the whole tones and prefer the "stinky notes." That's why they're so bored; same old same old. What if all you got to hear was stuff in 4/4 ?
Now, if those buglers transposed even to a minor key that might have invigorated those horses a bit. If they had bugles capable of quarter tones that would really do the trick (think of bugle calls that sound like Arabic or Persian music). Yeah, they need stinky notes.
