This instrument was designed and built while I was teaching a class on the Psalms of David.
He mentions singing the Psalms to a ten string lyre. And, that is exactly what this is.
It has a raw hide soundboard, ten steel strings, yarn wrapped arms (for color) and steel zither pins for tuning.
It is tuned to a pentatonic scales G, A, C, D, F, G, A, B flat, C, D.
The insertion of the B flat into the tuning really increased the music that can be played.
