Diatonic Autoharp with "6-7" tuning demo

6-7 tuning takes chromatic notes that are not in a diatonic scale and tunes them so the higher ones are tuned up and the lower ones are tuned down. Actually, the flats like Bb, Eb, and Ab are made sharp and the F# and C# are tuned down, BUT that's only the top-part of the harp, the lower strings are tuned the other way. This demo is not exactly that, but you get the idea.
