Well I’ve gotten the one about string color as well. I’ve had people come up to me and ask how long I’ll have to be playing before I can get rid of the colored strings.
One of the strangest idiotic requests I’ve had came from a bride who, just before the ceremony, asked me to quickly show her how to play “something” on the harp so that she could step over and play it during the ceremony. I was shocked but I did ask her if she had ever played harp or even piano before. Her reply was “no but it looks really easy.” I didn’t know whether to be insulted or complimented??? I just latched down the B and E pedals to create an F major glissando and told her to have at it! (It wasn’t my harp – one the bride’s family had borrowed)
