One of my neighbors has been practicing a saxophone piece for the past few weekends. He's been struggling but has improved over time. Today I picked up my guitar to try to figure out what he's playing. It's a fairly straight-forward, faintly Klezmer, D Aeolian mode spanning three octaves, broken into four phrases. It's not too difficult to play on the guitar, physically, but its twistiness must be more challenging on the sax. It's fascinating to hear him keep hammering on the piece and bursting out with a chromatic flourish whenever he screws up. I can't wait to hear him play it without error, one of these days.
