Jerusha, two pieces that come to mind are sold as Maestoso Harp Solos ($5. ). Included are Finlandia Theme, Sibelius, and March of the Priests, Mendelssohn; both arrangements by Herald Music are quite chordal in nature.
Two pieces that come to mind are Offrande by Tournier, and March of the Men or Harlach by Thomas. Offrande is in a publication called DEUX PIECES BREVE ET FACILE and contains another piece that I never played. But the Offrande is gorgeous.
