What are the examples of just intonation?

Just intonation is a system of musical tuning in which the frequencies of notes are related to each other by simple whole number ratios. This results in a more pure and consonant sound than equal temperament, which is the tuning system most commonly used in Western music today.

Here are some examples of just intonation:

* The major third interval has a frequency ratio of 5:4. This means that the frequency of the higher note is five times greater than the frequency of the lower note.

* The perfect fifth interval has a frequency ratio of 3:2. This means that the frequency of the higher note is three times greater than the frequency of the lower note.

* The octave interval has a frequency ratio of 2:1. This means that the frequency of the higher note is twice as great as the frequency of the lower note.

These are just a few examples of the many intervals that can be used in just intonation. With just intonation, the possibilities for creating rich and beautiful music are endless.
