Sid, I have similar problems, but my theory is that I feel safe on the keyboard or when singing. It’s what I “do” — what I have always done. The harp is rather new for me, so it is a little more shakey. Also I feel like I am playing the air sometimes. There is a totally different feel to playing strings than playing keys — I can’t verbalize what I’m trying to say properly……On the keyboard you have something fairly secure under your fingers. You don’t really have the same feel on a harp string……
However, overall I have come to the conclusion that it’s because it’s a new thing for me more than anything else, and the more I do it, the less freaked I get. It’s a matter of self-confidence and proficiency for me more than anything else.
