Thanks for the reply! I have a 26-string lever harp.
We’re using some exercises by Barbara Ann Fackler and an Italian book of harp drills that says copyright Italy in 1946. I just have photocopies, not the actual book, so I don’t know the title.
When I got bored of those (not mastered them, just bored of them, haha), I got the first Teach Yourself Harpsicle book and started playing All Through the Night. Thought I was doing a pretty good job of it until I played it for my teacher and discovered that the proper fingering is a little more tricky than I’d thought. So now I can crawl through one short song 😉
