Pythagorean tuning
Pythagorean tuning is an approach to tuning based on stacking pure fifthsIn just intonation, pitches a fifth apart have a 2:3 (“two-to-three") frequency ratio. If one pitch is at 300 Hz, a pitch a fifth higher is at 450 Hz. A pitch a fifth lower is at 200 Hz.Visit the link to learn more (i.e. fifths with an exact frequency ratio of 2:3).
