Someone just asked me how to find sheet music for a singing audition. I asked around a bit and came up with some answers, so I’m putting them here for safekeeping.
Scribd has easy-to-find sheet music to lots of pop and Broadway songs.
MusicNotes has lots of music, and a “transpose” feature, so you can shift the song into your preferred key before printing it. It even gives you a midi file to rehearse with. If only it would tell me how pretty I am, too. SheetMusicScore is another one to try.
BroadwayScoresAndSheetMusic is a site full of free scores to Broadway shows- it’s been taken down at the moment (likely getting slammed for copyright issues), but it might come back one day, so we’ve been advised to keep an eye on it- apparently it’s great.
One more thing- to rehearse with accompaniment in the original key, look no further than YouTube for “instrumental” or “karaoke” versions of many Bway and pop songs.
