This arrangement of Simon and Garfunkel's hit is played on a 5-chord zither made in East Germany sometimes during the 60s or 70s. It has single melody strings. Both single and double melody strings instruments are played exactly the same way. On a zither with double melody strings, both strings are tuned in unison.
