Abstract

The article focuses on Johannes Kepler's concept of relating planetary orbital motions to musical scales, illustrating how the angular velocities of planets at aphelion and perihelion correspond to musical notes and intervals. Using orbital eccentricity, a mathematical expression is derived to calculate the frequency ratio of these musical intervals, which generally aligns with Kepler's proposed planetary scales. This interdisciplinary connection between astronomy and music is presented as a pedagogical tool to engage students in introductory astronomy courses by linking scientific concepts to familiar experiences in music.
