The Savart wheel is an acoustical device named after the French physicist Félix Savart (1791–1841), which was originally conceived and developed by the English scientist Robert Hooke (1635–1703). A card held to the edge of a spinning toothed wheel will produce a tone whose pitch varies with the speed of the wheel.
