Pythagorean tuning
Examples
Also ditone and semiditone are specific for Pythagorean tuning, while tone and tritone are used generically for all tuning systems.
Because most fifths in Pythagorean tuning are in the simple ratio of 3:2, they sound very "smooth" and consonant.
By definition, in Pythagorean tuning 11 perfect fifths (P5 in the table) have a size of approximately 701.955 cents (700+ε cents, where ε ≈ 1.955 cents).
However, there will always be one wolf fifth in Pythagorean tuning, making it impossible to play in all keys in tune.
For a similar reason, each of the other interval types, except for the unisons and the octaves, has two different sizes in Pythagorean tuning.
For this reason, Pythagorean tuning is particularly well suited to music which treats fifths as consonances, and thirds as dissonances.
