Ben, it’s useful if you post what kind of harp you are playing: pedal or lever, and if lever, how many strings and if you have full levers or less. That said, you could make a personal list of titles of favorites you want to find, and then search harp music catalogs such as those from Vanderbilt, Lyon and Healy, Melody’s, Sylvia Woods, or Pilgrim Harps (England) and so on.There you may well find published favorites of pieces on your list. If some still cannot be found, look in piano catalogs (Alfred Publishing, Mel Bay, etc.) and if you are near a large music store, go and see if you or a helpful clerk can find some from your list that, before buying, you decide whether you could adapt them easily for your harp. You may not find any of your favorites that are composed later than about 1924, because of U.S.copyright restrictions. In Canada and other countries the laws for publication or recording are different. Naturally, living composers, and estates of recently died composers have rights to royalties from sales of their compositions. Anything in Public Domain (give a look to see what a large amount of composed music is there) is legal, however. If you never perform music for profit, don’t worry; you may play anything you like to relax and enjoy. You may need to change the key signature, leave out a few notes, or use enharmonic spelling (with the pedal harp), adapting from printed piano music that employs ten fingers instead of eight.
Good luck, and let us know how your search is going!

Ben, you might want to check out Cindy Horstman’s “Angelica.” It is a PDF download available from the Harp Column music store. You can listen to it first. I just bought the music and love it.

Hi Dawn, I performed this a few years ago. I will look for the program so I can check if what I remember about it is accurate!
