6-1 · Big Picture: Major Scale and Modes

Modes, finally demystified. You'll meet the seven modes of the major scale two ways: the textbook version (start the major scale on a different degree) and the far more useful version (the one note you change to brighten or darken the major scale). Ordered by brightness — Lydian down to Locrian — each gets a characteristic note and a chord it loves, and you'll see why the six that matter (Locrian sits this course out) are just the major and minor pentatonic scales you already know in disguise.

There are two mental models commonly used for thinking about the major scale modes. The first concept is treating a different note inside a major scale as the root. Much like you can create a minor pentatonic scale by starting a major pentatonic scale from its fifth note, you can create an Aeolian mode by starting a major scale from its sixth note. The second method is to think of modes in terms of how each scale degree relates to the corresponding scale degree in the major scale (e.g., the Mixolydian mode is the major scale with a flat 7th). The second mental model is more useful in practice, since it corresponds to how our ear hears the notes.

If we create a new scale by starting on each of the seven notes of the major scale, we get the following major scale modes, each commonly known by a Greek name. In this diagram, the notes of each scale are labeled with the original scale degrees from the major scale:

1 Ionian 1 2 3 4 5 6 7 1 2 Dorian 1 2 3 4 5 6 7 1 3 Phrygian 1 2 3 4 5 6 7 1 4 Lydian 1 2 3 4 5 6 7 1 5 Mixolydian 1 2 3 4 5 6 7 1 6 Aeolian 1 2 3 4 5 6 7 1 7 Locrian 1 2 3 4 5 6 7 1

The Ionian mode (built from the first scale degree) is exactly the same as the major scale, and the Aeolian mode (built from the sixth scale degree) is exactly the same as the natural minor scale.

A more practical way to arrange (and think about) the modes is brightness order. Here, the brightest, most major-sounding mode is at the top, and the darkest, most minor-sounding mode is at the bottom. In this diagram, the notes have been relabeled to reflect the intervals relative to the root of the scale:

4 Lydian 1 2 3 4 5 6 7 1 1 Ionian 1 2 3 4 5 6 7 1 5 Mixolydian 1 2 3 4 5 6 7 1 2 Dorian 1 2 3 4 5 6 7 1 6 Aeolian 1 2 3 4 5 6 7 1 3 Phrygian 1 2 3 4 5 6 7 1 7 Locrian 1 2 3 4 5 6 7 1

In this order, each mode differs from its neighbors by only one note.
