A rare five chord zither by Oscar Schmidt. Zithers preceded autoharps and were produced widely in Germany and other parts of Europe. Many modern autoharps harken from their design, then add a chord bar for producing multiple chords. Most zithers had between three and six chords on the left side (bass) with melodic strings on the right side. This harp has been retuned to the Crystal / D minor tuning used for autism and Asperger's Syndrome in children, and creating a tonality and ambience of safety and security. Although a modern harp, it never had chord bars, the apparatus which distinguishes it from autoharps.
