Demonstration device for sound figures, after Chladni

Why is the design and the material of a violin so important? The answer is simple: The way in which a sound box vibrates with a given tone determines the sound quality and timbre of a musical instrument. The first to show insight into the way objects vibrate was Ernst Chladni (1756-1827). He clamped regularly formed (round, square or triangular) glass plates at one point, scattered fine grains of sand onto them, and set the plate into vibration with a violin bow. The sand jumps away in places where the plate is heavily vibrating (the so-called ‘antinodes’) and the sand remains in places where the vibrations deaden each other (the ‘nodes’), resulting in the ‘nodal lines’ becoming clearly visible on the plate.
