Chromatic Intervals

Moving Beyond Diatonic Intervals

Now that we are familiar with the intervals of a major scale, we can now study the intervals that are not diatonic to the major scale. These chromatic intervals are described relative to the diatonic intervals and are determined by altering the diatonic notes of the major scale.

When naming chromatic intervals, we need to consider both the diatonic note and the mechanism by which the diatonic note is being altered. For example, using the C major scale as an example:

As D# and Eb are enharmonic notes, the intervals of an Augmented 2nd and a Minor 3rd are also enharmonic.

When altering the notes of the major scale, the following rules are used to determine the name of the resulting chromatic intervals:

Below is a list of the chromatic interval names, using the C major scale for reference
