Rick, This information is probably arriving way too late, but here's the layout on the chord section of my MacArthur Harp. Strings are given left to right.

First chord: C. Strings are E, G, bass C, C.

Second chord: G7. Strings are D, bass G, F, B.

Third chord: F. Strings are C, A, bass F, F.

Would it help you any to have the string specs? I have a book by Margaret MacArthur on how to play (and string) a MacArthur Harp.

Keith Young, a local instrument maker, was offered an original MacArthur harp. (Margaret's was custom-made as a reproduction of one that was found, stringless, in a Vermont barn.) Keith's has the original black finish, with gold lettering to show how it is strung. The treble part of the repro harps goes from G below middle C to C above middle C, no sharps or flats. The original has a treble in G, not C, starts on D, I guess. Keith says the chord layout is completely different.

Since you have the option of laying out your chords any way you please, I thought I'd tell you the chord layout on my 49-string zither as well. Five of the six chords are layed out, right to left, in arpeggios. The other, the A chord, has a weird arrangement. They go like this (right to left):

Bass C, GCE; BASS G, GBD; BASS F, ACF; BASS D, F#AD; BASS A, C#AE; BASS E, G#BE.

I gave the strings from right to left (or top to bottom depending on how you hold the zither) because that's how I play them. Wish I had taken the zither to your concert so you could see it and maybe even hear it. I can never count on its staying in tune when I haul it around. It's older than I am and twice as cranky.

Sorry I didn't get a chance to get on and send you this info yesterday. - Rita F
