Major and Minor Triads - 3D lissajous figure

thingiverse

# Two customizable 3D Lissajous figures. Viewed from each side, the *major triad* model shows the ratios of the notes in a major triad: the root, the major third and the fifth. When played in tune, the frequencies of these notes will be in the ratio 4:5:6. For example, an A major triad will have the frequencies 440:550:660. The minor triad model is similar. However, the ratio is more complex, 10:12:15. Notice how the *minor triad model* is more complex than the major triad model. In Western music, intervals with simple ratios sound more consonant, while intervals with more complex ratios sound more dissonant.
