Hi, Deb. That’s a pedal harp (Camac I think) and Rouet, in my opinion, is pretty hard for levers for what it is. It’s a very easy piece if you have pedals, but there are a lot of fast lever changes in it.
You might want to check out Sea Anemones by Patricia John, which has the same sort of descending three note arpeggio pattern but is more suited to the lever harp.
