and with autoharps, the large difference in length between many of the (usually)36 strings makes especially interesting changes. The shorter, tighter, thinner strings move less than the long thicker ones....so add this to temperature & humidity changes in the wood, and the need to 'adjust' for the way the ear hears higher & lower notes, and it is often more art than technology getting an autoharp to sound 'just right'.

Bryan Bowers refuses to use an electronic tuner, as he claims that the ideal tuning is slightly off what the tuner shows...plus, he tunes a G note a little different in a G chord than in a C chord, so he uses several 'harps, each adjusted for a couple of specific keys. ..Me, I can't hear the difference, so I just use my Korg and assume it's tolerable...*grin*
