Funny you should mention being in an orhestra without a pedal harp. My first orchestral encounter was about 4 and a half years ago. I auditioned for a summer youth orchestra (on lever harp) and got in. I brought my harp to the first rehearsal, all excited, and to my great disfortune, I found a huge pedal harp in the rehearsal room. My first thought was “what the hell am I supposed to do with this thing?” but after a week, I learned how to use the pedals. It very easy, the only thing you have to memorize is the order of the pedals: DCB EFGA , and after you do that, it’s all very very simple. Pedals are a LOT easier than levers, so the hard part is over!
