When I think of music played with harp, the images I immediately get are very clear: It’s either some angelic bliss or fairytalelike sweeping. And what also comes to mind is a fellow named Marx.
OH PEARLY HAVEN is a standard harp tune. No scary sounds, no strong rhythm, not much variation. Just some harpy stuff.
Modern concert harp is a pretty complex instrument, with 47 strings and several pedals. To be honest, I have no idea if this tune is actually playable or not. Maybe i will never know.
