I recently played a piece by Golijov called Zhang Zhou’s Dream. It was quite beautiful, but the harp part was not written in a very practical way. Lots of note clusters that involved growing an extra foot to change three pedals at a time. If you need my edited version, I can send it to you, if this is the piece.
I play second harp in the National Symphony and last week we did a concert opening with Webern Im Sommerwind, then the Golijov “She Was Here,” and after intermission Mahler 4. Soloist was Dawn Upshaw. The Golijov had just one harp part, but I assisted since there are two harps in the Webern. It is a beautiful setting of four Schubert songs, with a very prominent harp part. The opening is very sparkly with repeated patterns in the harp and celeste–this part is not sight-readable and would need some practice. The rest of the work is very playable, and fun and beautiful. The harp part is very prominent and exposed.
