Amyotrophic lateral sclerosis (ALS), sometimes called Lou Gehrig's disease, is a rapidly progressive, invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles.
The Alpine Scheitholt furnishes an example of this older type of European zither. By the late 18th century, two principal varieties of European concert zither had developed, known as the Salzburg zither (with a rounded side away from the player), and the Mittenwald zither (with both sides rounded).
No offense is intended toward my fellow musicians or fellow musicologists. Germany's national instrument, the zither, is famous for playing the entire score of the classic 1949 film The Third Man, which was the first and last anyone ever heard of it.
