My impression is that any classical school of dressage for Germany is buried in these comparisons outside of maybe the training scale, and instead “German” is equated with modern competition dressage, which IMHO we shouldn’t really do anymore…even if you blame the Germans for the current state of competition dressage.
Isn’t there a classical German school as well? (I mean, yes, surely there is, if all classical schools come back to the writings of master trainers from the cavalry? Or does classical mean something else?)
Is there a good resource somewhere that does a comparative analysis of these different schools? That doesn’t start and end with the description of what was easy/hard for the particular breeds they rode? Not that that is unimportant, but that must only be scratching the surface.
