Homemade Science with Bruce Yeany | Savart's wheel, Good science, bad music @YeanyScience | Uploaded November 2021 | Updated October 2024, 1 week ago.
Savart's wheel is a circular disc with symmetrical teeth on it's edge and was developed in the 1600's as a method of demonstrating the relationship of frequency and pitch. As the wheel rotates, a piece of card stock is held against the teeth to make a steady sound that changes in pitch according to the number of teeth on the wheel or the speed that it rotates.
