If you’re looking for new repertoire for two or three harps, you’re in luck! Several recent publications should fit the bill.
While not actually new, “Three Dances for Two Harps” by John Escosa is a new edition by Salvi Publications that now includes individual harp parts, measure numbers to aid in rehearsal, a full score, and easily readable font. These three original dances include a Gavotte, Minuet, and Gigue. Older harpists may remember the Longstreth & Escosa Duo, and this trio was a staple of their repertoire. Pedal changes are marked below the staff and there are no changes in the Gigue. They are suitable for intermediate to advanced players.
