A zither is a string instrument that’s played horizontally/face-up I think.
Has anyone figured out how one would theoretically tune it? I imagine it would be dangerous (slice cheese, blocks of ice) to tune the strings tight enough to produce a human-audible sound.
My friend said she saw this guy on a TV show, but there’s plenty of backup from other instrumentals in the video I saw. Maybe he’s doing the string version of lip-syncing?
I wonder if we are just hearing the overtones and not the main tone of the string?
