Harmonic motion
Harmonic motion can mean:
- The motion of a Harmonic oscillator (in physics), which can be:
- Keplers laws of planetary motion (in physics, known as the harmonic law)
- Quasi-harmonic motion: Unit hyperbola#Parametrization
- Musica universalis (in medieval astronomy, the music of the spheres)
- Chord progression (in music, harmonic progression)
