I have no idea what etude this is, but it's a fun, hoppety scale for octaves, intervals, and smooth shifting between them all. It could be Dont, but don't hold me to it ;)

It's really copyrighted, I'm sure, but please if someone can identify it (see attached PDF), having it here will certainly help to that end.

Oh, and while I'm at it, check out this Encyclopedia of the Violin.
