That's interesting. I'm surprised no-one's mentioned the pedals, to me that's the most difficult aspect of the concert harp (my sister is a harpist, among other things...you can see her in action here
). You set the key signature with the pedals, so if you've got anything chromatic or a sudden key change, you have to move the pedals to the corresponding sharps and flats (one pedal for each note, with three positions). Not only that, but you have to try and do it quietly!
