Guitar Scales | The Complete Guide

Jump to the interactive tool to experiment with the scales shown in the video above

This page will teach you everything you need to master guitar scales with proficiency.

After learning chords, the next most common step is to start playing single-note melodies over the entire neck, and knowing your scale patterns is vital for this process.

In the following, you'll learn the most common guitar scales, as well as basic theory knowledge about scale formulas and how to use them.

So let's get started!

Most Common Guitar Scales

Here below you find the diagrams and explanations for some of the most used guitar scales.

If need help to understand these diagrams, have a look at my how to read music for guitar tutorial.

Major Scale

The major scale is the foundation of Western Music so here it's the first in the list.

Major Pentatonic Scale

Pentatonic scales are composed of 5 notes (penta) and the Major pentatonic is a Major scale without the 4th and the 7th.

Minor Pentatonic Scale

The Minor pentatonic is another 5 notes scale.

Good to know: if you play the minor pentatonic in the key of E, we have a particularly easy fingering because we can use open strings.

The same concept can be applied to open major scales

Blues Scale

The Blues scale is a Minor pentatonic with a flattened 5th added. It has a unique sound that you immediately recognize.

Minor Scale

The minor scale is another important scale to learn, and it's relative to the major scale.

Dorian Scale

The Dorian scale is massively used in Jazz and Rock; it's a variation of the minor scale.

Mixolydian Scale

The Mixolydian scale is a Major scale with a flattened 7th, it has a Bluesy feeling.

Lydian Scale

The Lydian scale, thanks to its raised 4th, has an unique dreamy effect.

You can even mix two scales together to generate new interesting structures, as explained in this hybrid scales tutorial.

Music Theory: What Is A Guitar Scale?

Scales are not the same as chords. When we practice scales we play them one note at a time, unlike a chord in which you play all the tones simultaneously.

We can consider a scale as a way to go from one note (say C) to the same note one octave upper (one octave is 12 frets on guitar)

Let's see this example on the guitar: take the C note at the 3rd fret of the A string , and the C one octave upper, at the 15th fret of the same string.

If you count the number of the frets between the lower C and the higher C, you get 12. So this confirms that an octave spans 12 frets .

We have multiple ways to go from the lower C to the upper. We could play the frets 3, 5, 7, 8, 10, 12, 15, 15 or play only 3, 7, 9, 11, 15 or even play all the frets between the two C (that would be a chromatic scale)

Of course, this holds true for ascending and descending both (from the lower C to the upper and from the upper to the lower)

Basic Scale Theory

The most important thing you must understand is that scales are not patterns. See a scale as a sound: each scale type has its own characteristic sound. Patterns are just ways to play scales on the guitar fretboard, due to the nature of the instrument.

The relationship between each selected fret determines the scale structure and thus its name. We can create scales of all of types.

Each scale type has its own unique combination of distances between the frets in the octave. This is called scale formula.

In music theory, frets translate to semitones or half-steps. On guitar, it's safe to consider frets, semitones and half-steps the same measure.

Usually, there are 7 notes to each scale within a one-octave range, but not always: pentatonic scales have 5 notes, and there are even scales, like bebop scales, that have 8 notes!

Considering that the scale doesn't change with an octave change we don't need to repeat it past 7 notes.

A C scale will always end and start on a C, and the same for each successive note. So a C major scale spanning 2 octaves is simply:

C D E F G A B C D E F G A B C

Remember: Scale Patterns are Movable!

Did you notice that the C major scale pattern above is just four frets wide? We call these box shapes, they span 4, 5 or 6 frets.

The reason why guitarists prefer to play scales along these box patterns are that the motion is more efficient: 1 finger for each fret (we're going to see this topic in the following)

The great thing about a guitar scales box is that it will work anywhere you place it on the guitar as long as you follow the pattern.

Each scale type has a specific box pattern which can be shifted to other keys. So, for example, if we want to play a D major scale , we move up the C scale pattern by two frets. Want an F major scale? Move the C pattern up by 5 frets!

If you want to understand better how and why the frets are placed across the strings, have a look at the guitar notes tutorial .

Guitar Scales Exercises

Here below you find a great exercise that will help improve your scale speed and agility. It's based on the C major scale, I suggest approaching the pattern with the medium finger at the 8th fret.

Which Scales Should I Play Over This Chord?

This is a common question that often confuses beginners. It's common practice to play a major scale over a major chord, a minor scale over a minor chord, and so forth.

Things get complicated when the harmony becomes more complex: dominant, altered, diminished chords, to name a few.

Which scales play well over those chord types? A good approach is to check the tones that compose the chord and what scale matches well with them.
