I got four in youtube. The first two are from a concert which I participated in, it’s was in 2008, my first year of learning to play the harp. The last two were played on my two months old pedal harp. Apologies for the poor audio, didn’t have a proper video camera 🙂
I haven’t tried the Aoyama Etude 47E, however I have had a little play on the Aoyama Vega. I noticed that I needed a lot of strength to push the pedals and to pluck the strings, overall it wasn’t easy to play.
Due to where I live, there’s not many harp technicians around, so
