Modes Compared: From Brightest to Darkest

By Interactive Chord Finder · · 7 min read

Seven modes, one parent scale, and a great deal of avoidable confusion. Most explanations hand the modes over one at a time, which tells you what each one is but never how they relate. This page does the opposite. It lines all seven up next to each other, orders them by brightness, and helps you pick the one you actually want.

Hear the Spectrum Before You Read About It

Pick a root note below and leave it fixed. Then move the scale selector through Lydian, Ionian (major), Mixolydian, Dorian, Aeolian (natural minor), Phrygian and Locrian in that order, playing each one as you go. Keeping the root still is the whole point: you are listening to a single sound go one degree darker at a time. Reading about that takes several minutes, hearing it takes about thirty seconds, and only one of the two sticks.

The Brightness Spectrum

Modes are normally taught in the order they occur in the major scale: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian. That order is a fact about the parent scale and says nothing about how the modes sound. Reorder them by brightness and the whole system collapses into one straight line, with exactly one note changing at each step.

ModeWhat darkens it compared to the mode above
LydianNothing, this is the brightest mode
IonianThe ♯4 becomes a natural 4
MixolydianThe 7 becomes ♭7
DorianThe 3 becomes ♭3
AeolianThe 6 becomes ♭6
PhrygianThe 2 becomes ♭2
LocrianThe 5 becomes ♭5

Seven modes, six changes, one note each time. The degrees fall in the order 4, 7, 3, 6, 2 and 5, which is not a coincidence: that is the order flats appear in key signatures, running down in fifths. If you already understand the circle of fifths, the brightness spectrum is that same circle applied to a single root instead of to a set of keys. Step one place flatwards and you land on the next mode down.

All Seven Modes Side by Side

Same information, laid out as degrees. Every mode below is measured against the major scale on the same root, so a plain number means the note is where the major scale puts it and an accidental means it has moved.

Lydian123♯4567

Locrian1♭2♭34♭5♭6♭7

Read the table downwards rather than across and the accidentals form a staircase. Once a degree has been lowered it stays lowered for every mode below, so the accidentals only ever accumulate. That is why the modes near the bottom feel so much heavier: Locrian is not darker than Phrygian by mood alone, it is darker by one more flattened note.

Each Mode Is Its Neighbour, Give or Take One Note

Nobody memorises seven separate interval formulas, and nobody needs to. You already know two scales, the major scale and the natural minor. Every other mode is one of those two with a single note moved.

ModeRemember it as
LydianMajor with a ♯4
IonianThe major scale itself
MixolydianMajor with a ♭7
DorianNatural minor with a raised 6th
AeolianThe natural minor scale itself
PhrygianNatural minor with a ♭2
LocrianPhrygian with a ♭5

The note that moves is also the note that carries the character, which makes it the note to lean on when you play. A Dorian line that never touches the raised 6th is indistinguishable from natural minor, and a Lydian line that avoids the ♯4 is just the major scale wearing a different label.

Parallel or Relative, and When Each One Helps

Two descriptions of D Dorian are in circulation and both are correct. The relative description is “the white notes starting on D”, which places Dorian as the second degree of C major. The parallel description is “D minor with a raised 6th”, which compares Dorian to the scale on the same root. They describe the same seven notes and they are useful at different moments.

Relative thinking is faster for finding notes. If you know a piece sits in one key signature, you can play the parent scale and let the harmony decide which mode you are in. It also explains why the modes exist at all.

Parallel thinking is faster for making decisions. It tells you immediately which single note distinguishes the mode you want from the one you know, and that is what you need mid-phrase. It is also the only framing that survives a key change part way through a tune.

There is one trap worth naming. Relative thinking tempts players into “just play C major over the D minor chord”, and the result usually sounds like C major, because nothing in the line points at D. Modes are established by harmony and emphasis, not by which note you happen to start on. A drone, a pedal bass or a vamp that refuses to resolve will do more for a modal sound than any amount of correct note choice.

The chord column matters more than the genre column. A mode is only audible if the harmony holds still long enough for its characteristic note to register, which is why modal writing tends to use one chord for bars at a time rather than a busy progression. If you are unsure which chords a given mode generates, build them from its own degrees and the answer is immediate: diatonic chords work the same way in a mode as they do in a key.

Why Locrian Is the Odd One Out

Six of the seven modes have a perfect 5th above the root, so their tonic triad is either major or minor. A major or minor chord can sound like home, which is all a key centre really requires.

Locrian has a ♭5, so its tonic triad is diminished and its tonic seventh chord is m7♭5. Neither of those is stable. A diminished triad is defined by wanting to go somewhere else, so a piece in Locrian is a piece whose home chord is asking to leave. That is not a matter of taste or fashion, it is a structural property of the mode, and it is why Locrian has almost no repertoire while the other six have centuries of it.

The practical consequence is that Locrian is a chord scale rather than a key. It is the natural note set over a half diminished chord, and a half diminished chord in real music is usually the ii of a minor ii V i rather than a destination. Treat Locrian as a colour that lasts a bar or two and it is genuinely useful. Treat it as a key and you will spend the whole piece resisting the pull towards the ♭2 or the ♭5.

So the honest summary is six usable modes and one that completes the set. The minor family covers the same problem from another direction, and natural, harmonic and melodic minor show what happens when composers alter a mode to fix an unstable chord instead of living with it.

Every Mode in Every Key

Each mode below links to a dedicated page for all twelve keys, with the notes, the fingering and the diatonic chords worked out. The Ionian links go to the major scale pages and the Aeolian links go to the natural minor pages, because those are the same scales under different names.
