This one-stringer was designed for use in an ensemble which plays only the tones of the harmonic series. It uses the same trick described for the Harmonic Zither, in which a string is divided into two segments by a mid-string bridge. The player plays on one side of the bridge. The pickup is located under the unplayed string segment on the other side, where it picks up sympathetic vibrations from the played side opposite, but only at frequencies that this unplayed segment can support. The supported frequencies are those of the unplayed segment’s harmonic series. Tall frets on the played side help the player to produce the required tones; alternatively, a slide will also work. The center-bridge filtering effect helps create a distinctive tone quality.
