The following is a list of intervals of meantone temperament. These intervals constitute the standard vocabulary of intervals for the Western common practice era. Here 12edo refers to the size of the interval in 12 equal divisions of the octave temperament, and 50-equal divisions of the octave to the size in 50edo and 88edo. Fifty edo was chosen because it is a meantone tuning, which like 12edo, makes all intervals come out to an integer number in terms of cents, and 88edo because it produces particularly consonant music. The column of ratios gives a ratio or ratios approximated by the interval in septimal meantone temperament. An augmented interval is increased by a chromatic semitone, and a diminished interval decreased.
