5 Most Important Guitar Scales For You To Learn

A scale is a group of notes played in order, forming a pattern. Scales are used to create melodies, bass lines, riffs, and lead guitar solos. Each scale has its pattern on the fretboard, and learning them takes practice.

Here are the major guitar scales you should try learning.

The Major Scale

Even if you have no idea about scales, there’s a great chance that you must have heard of The Major Scale. Aside from being one of the most popular scales, it’s also the easiest to learn. 

They are formed by playing tones and semitones in a sequence and are made up of seven notes. Major scales are perfect for solos and are the foundations of most western music today. Some popular major scale songs are Honky Tonk Woman by the Rolling Stones and “ABC” by the Jackson 5.

Editor’s Comment

In guitar music, the distance between two frets is a semitone, while a tone is the distance of two semitones.

Major Pentatonic Scale 

No matter the number of guitar scales you learn, you’ll always find yourself returning to the major pentatonic scale. This is purely because of the influence it has had on guitar music in general; your favorite guitar songs are most likely products of the major pentatonic scale.

The major pentatonic scale is very similar to the major scale. The only difference between them is that while the major scale comprises seven guitar notes, the major pentatonic scale is made of five. That’s why it has the Penta prefix. 

The two missing notes from the major scale that make up the major pentatonic scale are the fourth and seventh. This change allows for more freedom to use notes when soloing and improvising.

The Natural Minor Scale

After you have learned the two major scales, you can start learning some of their modes. An excellent way to begin with is the natural minor scale.

The natural minor scale is formed by simply lowering the sixth, fifth and third scale degrees by a half step.

The natural minor scale can be challenging to learn, and it’s advisable to practice it using two strings. Get acquainted with this before you combine them and play the full shape.

The Minor Pentatonic Scale

The Minor Pentatonic Scale is an offspring of the major pentatonic scale. It’s also one of the easiest scales to play on the guitar. 

The scale is six strings shaped and has only two patterns, making it easier to memorize.

The Blues Scale

The blues scale’s name is a little misleading. It’s not only used in playing blues music, but you can also use it for a ton of other genres.

If you’ve fully understood the minor pentatonic scales, the blues scale will be easy. The only difference between the two is the addition of a single note, that’s two for the whole shape. 

You can practice this scale by soloing popular blues songs.
