DescriptionSize of intervals in D-based symmetric Pythagorean tuning.PNG	English: Sizes in cents of the 144 intervals in the D-based Pythagorean tuning system. Bold font indicates just intervals. Wolf intervals were highlighted in red. The values were accurately computed using Microsoft Excel, then rounded to integers.

Wolf intervals are operationally defined herein as intervals composed of 3, 4, 5, 7, 8, or 9 semitones (i.e. major and minor thirds or sixths, perfect fourths or fifths, and their enharmonic equivalents) the size of which deviates by more than one syntonic comma (about 21.5 cents) from the corresponding justly intonated interval. Intervals made up of 1, 2, 6, 10, or 11 semitones (e.g. major and minor seconds or sevenths, tritones, and their enharmonic equivalents) are considered to be dissonant even when they are justly tuned, thus they are not marked as wolf intervals even when they deviate from just intonation by more than one syntonic comma.
