(Harp). Sylvia Woods has made two harp arrangements of "The Star-Spangled Banner." The first version, in the key of C, can be played on lever or pedal harp. If your lever harp is tuned to the key of C, this is the version you should play. The second arrangement, in the key of B-flat, is for lever harps tuned to flats or pedal harps. B-flat is the key that is most commonly used when the song is sung.
