Sometimes when I'm working Vinings' Range Songs, I'll play thru an octave down first, and then as written. I get a double benefit -- working the low range (and I love playing low ) and getting a chops break from having been screeching on the previous one. I don't think I've done Rochut an octave down. I can see another benefit from that -- building fingering technique in the low range, because the fingerings there are different from the fingerings an octave higher.
