2.1 Major scales

Seven scales, each with its own character, from the same set of notes

Key Concepts

What are Modes?

7 different scales derived from the major scale, each starting from a different degree. Same notes, different character.

Order of Brightness

From the darkest to the lightest: Locrian, Phrygian, Aeolian, Dorian, Mixolydian, Ionian, Lydian.

Key Feature

Each mode has a note that distinguishes it (Dorian: minor 6th, Phrygian: flat 2nd, Lydian: sharp 4th, Mixolydian: flat 7th, Locrian: flat 5th).

Use in jazz

Each chord has an associated mode: Dm7→Dorian, G7→Mixolydian, Cmaj7→Ionian/Lydian, Bm7♭5→Locrian.

Modal Interchange

Borrowing of chords from parallel modes (e.g. ♭VI and ♭VII from the Aeolian mode in an Ionian progression).

An Introduction to Musical Modes

What are Modes?

There are seven different modes (or modal scales), all derived from the major scale, each beginning on a different degree. Each mode has a unique tonal character determined by the specific arrangement of its intervals.

The same set of notes can create seven completely different atmospheres depending on which note we choose as the tonic (tonal centre). It is like looking at the same landscape from seven different angles: each perspective reveals something unique.

Practical example:

Starting with the C major scale (C-D-E-F-G-A-B), we can derive 7 modes:

  • Starting from C → Ionian (C major)
  • Starting with D → Dorian (Dorian mode)
  • Starting with E → Phrygian (Phrygian E)
  • Starting with F → Lydian (F Lydian)
  • Starting with G → Mixolydian (G mixolydian)
  • Starting with A → Aeolian (A minor natural)
  • Starting from B → Locrian (Si locrio)

Parallel Modes: All Modes in C (Do)

To better understand the differences between the modes, it is helpful to compare them all starting from the same tonic. Here are all the modes built on the note Do (C):

Mode Notes Scala Madre Accidental vs Maggiore
C Ionian C-D-E-F-G-A-B C major (1st degree) —
C (Dorian) C-D-E♭-F-G-A-B♭ B♭ major (II degree) ♭3, ♭7
C Phrygian C-D♭-E♭-F-G-A♭-B♭ A♭ major (third degree) ♭2, ♭3, ♭6, ♭7
C Lydian C-D-E-F♯-G-A-B G major (4th degree) #4
C Mixolydian C-D-E-F-G-A-B♭ F major (5th degree) ♭7
C Aeolian C-D-E♭-F-G-A♭-B♭ E♭ major (VI degree) ♭3, ♭6, ♭7
C Locrian C-D♭-E♭-F-G♭-A♭-B♭ D♭ major (VII degree) ♭2, ♭3, ♭5, ♭6, ♭7
Practical Method: To construct a scale based on a specific tonic (e.g. C Dorian), identify the root scale (B♭ major) and play its notes starting from the desired tonic (C). Alternatively, alter the major scale according to the formulas above.

Derived Modes: The 7 Modes of the C Major Scale

This is the most intuitive way to understand modes: starting with a major scale (C major), begin with each degree to arrive at a different mode.

Modes of C major
C major scale: C – D – E – F – G – A – B – C
I – C Ionian: C–D–E–F–G–A–B–C
II – D Dorian: D–E–F–G–A–B–C–D
III – E Phrygian: E-F-G-A-B-C-D-E
IV – F Lydian: F-G-A-B-C-D-E-F
V – G Mixolydian: G-A-B-C-D-E-F-G
VI – Aeolian: A-B-C-D-E-F-G-A
VII – B Locrian: B–C–D–E–F–G–A–B

The Seven Ways in Detail

Each mode has unique tonal characteristics, determined by its specific pattern of whole and semitone steps, its characteristic note and its associated harmony.

1. Ionian – The Major Mode

The Ionian mode is identical to the major scale. It is the brightest and most stable mode, with a major third and a major seventh.

Character: Cheerful, joyful, steady, resolute

Uses: Pop music, classical music, Imaj7 and IVmaj7 chords in jazz

Example (Ionian C): C-D-E-F-G-A-B-C

Famous songs: “Let It Be” (The Beatles), “Don’t Stop Believin’” (Journey)

Associated chord: maj7, maj9, maj13

2. Dorian – Il Minore Jazz

The Dorian mode is like the natural minor mode but with a major 6th. It is the most commonly used minor mode in jazz and funk because of its sophisticated sound.

Character: Subtle yet vibrant, sophisticated, funky

Usage: Jazz (IIm7), funk, rock. A ‘modern’ substitute for the natural minor

Example (D Dorian): D-E-F-G-A-B-C-D

Famous tracks: "So What" (Miles Davis), "Evil Ways" (Santana), "Scarborough Fair"

Distinctive note: major 6th (the difference from the natural minor)
Associated chords: m7, m9, m11, m13

3. Phrygian – The Spanish Way

The Phrygian mode features a minor second (a semitone from the tonic), creating an exotic and intense sound, typical of flamenco and Spanish music.

Character: Dark, exotic, Spanish, mysterious, oriental

Used in: Flamenco, metal, Middle Eastern music. Rarely used in traditional jazz

Example (E Phrygian): E-F-G-A-B-C-D-E

Famous tracks: “White Rabbit” (Jefferson Airplane), traditional flamenco music

Characteristic note: ♭2 (minor second), creates the ‘Spanish sound’
Associated chord: m7, sus♭9

4. Lydian – The Dreaming Mode

The Lydian mode is like the major mode but with an augmented 4th (#4 or #11), creating an ethereal, dreamy and modern sound. It is the brightest mode.

Character: Bright, dreamy, ethereal, modern, cinematic

Usage: Modern jazz (Imaj7), film scores, progressive rock. A ‘modern’ alternative to the Ionian scale

Example (F Lydian): F-G-A-B-C-D-E-F

Famous tracks: “Flying in a Blue Dream” (Joe Satriani), “The Simpsons Theme”, soundtracks by John Williams

Characteristic note: #4 (augmented fourth), avoids the ‘heavy’
perfect fourth Associated chord: maj7#11, maj9#11

5. Mixolydian – The Dominant Mode

The Mixolydian scale is like the major scale but with a minor 7th, creating the characteristic sound of dominant 7th chords. It is widely used in rock and blues.

Character: Bluesy, dominant, rock, resolute but not definitive

Uses: Rock, blues, jazz (V7), country. The ‘blues-rock sound’

Example (G Mixolydian): G-A-B-C-D-E-F-G

Famous songs: “Sweet Home Alabama” (Lynyrd Skynyrd), “Norwegian Wood” (The Beatles)

Characteristic note: ♭7 (minor seventh), defines the dominant
sound Associated chord: 7, 9, 13 (dominant chords)

6. Aeolian – The Natural Minor Mode

The Aeolian mode is identical to the natural minor scale. It has a classical, melancholic and natural sound, and forms the basis of the minor key.

Mood: Sad, melancholic, natural, classic

Usage: Rock, pop, classical. In jazz, it is less common than the Dorian mode (because of the minor 6th)

Example (Aeolian): A-B-C-D-E-F-G-A

Famous songs: “Stairway to Heaven” (Led Zeppelin), “Losing My Religion” (R.E.M.)

7. Locrian (Locrian) – The Unstable Mode

The Locrian mode features a diminished fifth, making it very unstable and dissonant. It is the darkest and most tense mode, and is rarely used as a tonal centre.

Mood: Unstable, tense, discordant, unsettling

Usage: Jazz (VIIm7♭5), metal, horror. Rarely used for entire melodies

Example (B Locrian): B-C-D-E-F-G-A-B

Famous tracks: “Army of Me” (Björk), used in short sections to build tension

Characteristic note: ♭5 (diminished fifth), creates harmonic
instability Associated chord: m7♭5 (semi-diminished)

Order of Brightness by Mode

Modes can be ordered from the darkest (with the most flat notes) to the brightest (with the most sharp notes compared to the major scale). This helps to understand their emotional character.

Locrian
Phrygian
Aeolian
Dorian
Mixolydian
Ionian
Lydian
Mode Accidental vs Maggiore Feeling
Locrian ♭2, ♭3, ♭5, ♭6, ♭7 (5 flats) Utter darkness and tension
Phrygian ♭2, ♭3, ♭6, ♭7 (4 flats) Very dark, exotic
Aeolian ♭3, ♭6, ♭7 (3 flats) Natural, melancholic minor key
Dorian ♭3, ♭7 (2 flats) Younger, but full of hope
Mixolydian ♭7 (1 flat) Promising but not definitive
Ionian None (major scale) Bright, steady, joyful
Lydian #4 (1 sharp) Maximum brightness, ethereal
Practical Application: In composition, you can create emotional progressions by gradually moving from dark modes to bright ones (or vice versa). Example: Phrygian → Dorian → Mixolydian → Lydian creates an arc from darkness to light.

Modal Interchange

Modal interchange (or modal borrowing) involves ‘borrowing’ chords from parallel modes (modes with the same tonic but different notes). It is a powerful technique for adding harmonic colour.

Common Borrowings in Major Keys

In a scale progression in C major (C Ionian), we can use chords from C Dorian, C Aeolian, C Phrygian, etc.

Agreement Reached Source Mode Function Examples
♭VII (B♭ in C) C Mixolydian Minor subdominant "Let It Be" (The Beatles)
♭VI (A♭ in C) C Aeolian Minor subdominant "Creep" (Radiohead)
iv (F major) C Aeolian/Dorian Minor subdominant "Space Oddity" (Bowie)
♭III (E♭ in C) C Phrygian Through a minor Rock progressions
♭II (D♭ in C) C Phrygian Tritone substitute Jazz, film noir
Practical Example: ‘Creep’ by Radiohead

The progression in ‘Creep’ is a perfect example of a modal interchange in the key of G major:

G (I) – B (III) – C (IV) – Cm (iv)

  • G, B and C belong to the Ionian (major) scale
  • The ‘Cm’ key is borrowed from the Aeolian (natural minor), creating the melancholic tone characteristic of the piece

Practical Application in Jazz

In jazz, each chord in a progression can be associated with a specific mode for improvisation. This system is known as the ‘scale-chord approach’ or modal jazz.

Example: II–V–I in C major

Chord progression: Dm7 – G7 – Cmaj7
Dm7

Second degree (supertonic)

Dorian

D-E-F-G-A-B-C
Grade: 6M (B)
G7

V degree (Dominant)

G Mixolydian

G-A-B-C-D-E-F
Key note: ♭7 (F)
Cmaj7

I degree (Tonic)

C Ionian or Lydian

C-D-E-F-G-A-B (Ionian)
C-D-E-F♯-G-A-B (Lydian)
Lydian is more modern
Advanced Tip: In modern jazz, it is common to use the Lydian mode over Imaj7 rather than the Ionian mode to achieve a more modern and sophisticated sound. The #4 avoids the ‘heaviness’ of the perfect 4th.

How to Recognise Modes by Ear

Recognising listening modes takes practice, but there are certain sonic characteristics that help you identify them quickly.

Method 1: Key Feature

Listen to the characteristic note that distinguishes each mode:

  • Dorian: Listen to the 6th M (a ‘jazzy’ sound)
  • Phrygian: ♭2 immediately after the tonic (Spanish mode)
  • Lydian: #4 creates a sense of ‘lightness’ (avoids the tension of the 4th)
  • Mixolydian mode: ♭7 over the major third (blues-rock sound)
  • Locrian: ♭5 creates extreme instability
Method 2: Greater or Lesser?

First step: is it a major or minor third?

Major Third (bright):

  • Ionian (the most ‘standard’)
  • Lydian (an ‘ethereal’ sound for #4)
  • Mixolydian (a ‘bluesy’ sound for ♭7)

Minor Third (sharp):

  • Aeolian (the ‘classical’ minor)
  • Dorian (has 6ªM, brighter)
  • Phrygian (the ♭2 makes it sound exotic)
  • Locrian (the ♭5 makes it unstable)
Listening Exercise

Try this exercise on the piano or with an instrument:

  1. Play a drone (held note) on C
  2. Play the Dorian C scale (C-D-E♭-F-G-A-B♭)
  3. Highlight 6ªM (A) — listen for the ‘jazzy’ sound
  4. Repeat using other methods, always emphasising that characteristic note

Mode Grado Pattern Key Feature Agreement Character
Ionian I T-T-S-T-T-T-S — (major scale) maj7 Bright, stable
Dorian II T-S-T-T-T-S-T 6th major m7 Jazzy Minor
Phrygian III S-T-T-T-S-T-T ♭2 (minor second) m7 Exotic, Spanish
Lydian IV T-T-T-S-T-T-S #4 (augmented fourth) maj7#11 Dreamy, ethereal
Mixolydian V T-T-S-T-T-S-T ♭7 (minor seventh) 7 Dominant, bluesy
Aeolian VI T-S-T-T-S-T-T — (natural minor) m7 Melancholic, classic
Locrian VII S-T-T-S-T-T-T ♭5 (diminished fifth) m7♭5 Unstable, tense

Tips for Studying Modes

  1. Learn one at a time: Start with Dorian and Mixolydian (the most commonly used in jazz), then add Lydian, Phrygian and Aeolian. Leave Locrian until last.
  2. Use the drone: Play a sustained note (drone) and improvise over it using the mode. This establishes the tonal centre and helps you perceive the modal colour.
  3. Emphasise the characteristic note: When improvising, frequently return to the characteristic note (M6 in the Dorian mode, #4 in the Lydian mode, ♭2 in the Phrygian mode, etc.).
  4. Compare parallel modes: Play all the modes in the key of C to hear the differences. Always start with the tonic, C, and listen to how the tone changes.
  5. Study modal pieces: Listen to and analyse: ‘So What’ (Dorian), ‘Scarborough Fair’ (Dorian), ‘The Simpsons Theme’ (Lydian), flamenco music (Phrygian).
  6. Practise these techniques on standard jazz scales: Apply the chord-scale system to II-V-I progressions. Play Dm7 with the Dorian scale, G7 with the Mixolydian scale, and Cmaj7 with the Lydian scale.
  7. Transcribe modal improvisations: Transcribe solos by Miles Davis, John Coltrane and Herbie Hancock. Note how they use the characteristic notes of the modes.
  8. Compose short modal phrases: Create melodies of 4–8 bars in a single mode. This develops your ear for modes better than simply playing scales up and down.

Common Mistakes to Avoid

  1. To think that modes are simply scales: Modes are not ‘alternative scales’. They are tonal centres with their own unique character. The Dorian mode is not ‘the notes of C major starting from D’; it is D as the tonic, with a major 6th and a flat 7th.
  2. Playing scales mechanically: Playing “D-E-F-G-A-B-C-D” over a Dm7 chord will not create a modal sound unless you establish D as the tonal centre. Use drones and pedal points, and emphasise the tonic.
  3. Ignoring the characteristic note: If you play a D Dorian scale whilst omitting the major 6th (B), it will sound like natural D minor. The characteristic note is what defines the mode.
  4. Confusing derived and parallel modes: Dorian (the second degree of C major) and C Dorian (C–D–E♭–F–G–A–B♭) are two different concepts. The former is ‘derived’, the latter is ‘parallel’.
  5. Using Locrian as the tonal centre: Locrian contains a ♭5, so there is no perfect fifth to provide stability. It is almost impossible to make it sound like a ‘home’ key. Use it on Xm7♭5 in progressions, not as the tonic of a piece.
  6. Always apply the same mode to a chord: A Dm7 can be Dorian (in a II-V-I progression), but also Phrygian (if it is the IIIm7) or Aeolian (if it is the VIm7). The harmonic context determines the mode, not just the type of chord.
  7. Skipping the Ionian and Aeolian modes: Many students overlook the Ionian (major) and Aeolian (natural minor) modes because they ‘already know them’. But understanding them as modes is essential for grasping the other five.
