Hi
I play folk harp myself, and never wanted to play pedal harp really.
I’ve been teaching myself for almost a year and a half. Teachers are
hard to come by in these parts (I live in Norway), and finally a few
months ago I found one who was willing to give me a lesson each month.
She plays the pedal harp, and when I got to my first lesson, I played
one of her pedal harps. I found the transition went remarably well,
although I haven’t touched the pedals yet. The only thing is that the
string tension is very probably different from your folk harp – you
should expect to have to play harder on the strings in order to produce
enough sound.
