Thank you to Dr. Franz Schenk for his effort in digitizing and sharing this copy of Wilhelm Moralt's self-study method for students of the 20 - 30 stringed zither. Moralt's zither method is a rarity and is mentioned in the Handbuch der Musikalischen Literatur, published in 1852. Revised copies continued to appear for years afterwards.
