Learning a Rhapsody in Blue solo: http://img.photobucket.com/albums/v665/HeliosEntity2/RhapsodyInBlue.png

Check out the third measure on the third system down. See how it's an octave lower for all of the third measure and part of the fourth? I'm not really sure why the octave notation cuts off two notes into the fourth measure, since it looks like it's supposed to be a long continuous run, and it sounds strange if you suddenly jump up an octave in the middle of all that. Any ideas on what would be correct?

Also, just before the third measure there, there's a sforzando sign, but with an "approximately equal to" sign like ≈ instead of a z. What's that all about?

Good luck. My eyes cant see anything atm

hehe nice
