Diatonic Scales & Modes for Guitar
Learn the seven diatonic modes and see how scales, intervals and patterns connect across the guitar fretboard.
This collection includes printable guitar scale charts for the diatonic modes, 3-note-per-string patterns, pentatonic scales and blues-scale variations. Use them as quick reference material for theory, fretboard study, improvisation and technique.
For an interactive way to explore scales and modes on the fretboard, use FRETTR. For more practical theory guides, explore Music Theory & Rhythm.
What Are the Seven Diatonic Modes?
The seven diatonic modes are Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian. They are built from the same seven-note diatonic scale, but each mode starts from a different scale degree and has its own interval structure and sound.
On guitar, learning these modes helps you understand how scale patterns connect across the fretboard and how the same notes can create different tonal colours.
Guitar Scale & Mode PDF Charts
Use the downloadable PDF resources below as quick-reference charts for scales, modes, key signatures and fretboard patterns.
Table of Diatonic Scales
This reference table brings together the seven diatonic modes — Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian — with their scale degrees, corresponding triads and seventh chords.
It also includes sharps and flats for identifying keys from their key signatures, plus the circle of fourths and fifths with major keys and their relative minor scales.

Table of Diatonic Scales
All seven diatonic modes — Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian — in one clear reference table, with scale degrees and their corresponding triads and seventh chords. Sharps and flats help you quickly identify a key from its key signature, and the chart also includes the circle of fourths and fifths with major keys and their relative minor scales.
Diatonic Scale & Modes Grid
All seven modes of the C diatonic scale presented graphically. Each mode is given a Roman numeral from I to VII, making it easy to compare the seven modes visually.
Diatonic Scale – 3 Notes per String
All seven modes of the C diatonic scale presented as 3-note-per-string patterns. These patterns are useful for changing positions quickly across the neck and for developing speed with techniques such as speed picking, hammer-ons, pull-offs and tapping.
Pentatonic Scale & Modes
A pentatonic scale is a five-note scale — penta means five. Compared with the diatonic scale, scale degrees 4 and 7 are omitted, resulting in five modes instead of seven. Pentatonic scales are widely used in styles such as funk, pop, rock, metal and many others.
Pentatonic Scale + Minor Blue Note
This variation adds an Eb — b3/#2 relative to the relative major key, or b5/#4 relative to the relative minor key. This extra note is called the minor blue note.
Although the resulting scale is commonly called the minor blues scale and has a bluesy sound, it is used in many styles beyond blues. It can be applied over both minor and major chords, as well as minor and major blues progressions.
Pentatonic Scale + Major Blue Note
This variation adds a Db — b2/#1 relative to the relative major key. This extra note is called the major blue note.
The major blues scale is more limited in its application and is mainly used over major chords and major blues progressions. It has a brighter, more upbeat blues character.
Put These Scales Into Practice
A scale chart is useful as a reference, but the real progress comes from seeing, hearing and playing the patterns in a musical context.
See Scales & Modes on the Guitar Neck
Use FRETTR to explore roots, notes, scale degrees, modes and 3-note-per-string patterns directly on the fretboard.
Practice Scales With Drum Grooves
Use GROOVR to practise scale patterns, sequences and improvisation with real rhythmic movement instead of playing them in isolation.
Learn to Hear Scales & Modes
Use Scale Hearo to train your ear to recognise scales, modes and tonal colours instead of relying only on visual patterns.

Frequently Asked Questions About Diatonic Scales & Modes
What is a diatonic scale on guitar?
A diatonic scale is a seven-note scale built from a specific pattern of whole and half steps. On guitar, the same seven notes can be played across different positions on the fretboard and used to form the seven diatonic modes.
What are the seven diatonic modes?
The seven diatonic modes are Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian. Each mode starts from a different degree of the diatonic scale and has its own interval structure and tonal character.
Are guitar modes different scales?
Modes can contain the same notes when they come from the same parent scale, but they use a different tonal centre. For example, the modes of C major all contain the notes C, D, E, F, G, A and B, but each mode treats a different note as its root.
What does 3 notes per string mean?
A 3-note-per-string pattern places three scale notes on each guitar string. These patterns make it easier to move across the fretboard and are commonly used for alternate picking, legato, hammer-ons, pull-offs and other speed-oriented techniques.
What is the difference between a diatonic scale and a pentatonic scale?
A diatonic scale contains seven notes, while a pentatonic scale contains five. The common major and minor pentatonic scales omit two notes from their corresponding diatonic scales, creating simpler patterns that are widely used for riffs, melodies and improvisation.
