I tend to breathe a lot, so hopefully you don't have to take as many breaths as me! But I played this for an audition and I breathed after the D in measure 74, the B in measure 79, optionally the E in measure 81 (and repeat), the D in measure 82, the F# in measure 85, and the eighth note C in measure 88. I also recommend playing it faster than marked--I played it anywhere from quarter note equals 132 to 136. Experiment with right hand middle finger F#s in measures 86-87. Good luck!
