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).
Zither (/ Ë z Éª Ã° Ér, Ë z Éª Î¸-/; German:) is a class of stringed instruments. The word Zither is a German rendering of the Latin word cithara, from which the modern word guitar also derives.
