Become familiar with the shape of major scales
Introduction
Here are a collection of G Major exercises that are designed to help you better visualize the major scale. I chose G Major because G Major/E minor is probably the most common key on the guitar. Why do I say this? Well, mainly because the open strings are a mix of G Major and E minor chords (E minor is the relative minor of G Major). When the root chords of any key are formed in the open strings, that means you can:
- Take advantage of open strings when playing chords and scales.
- There are plenty of natural harmonics within the key available.
So, here are several exercises with explanations of each and suggestions at what to pay attention to.
Exercises
The first one is a very simple one octave scale played on the high E-string. This isn’t the most efficient way to play a scale, but it provides important visual cues: It clearly lets you see the scale pattern. In this case you can easily see the whole-step/half-step relationship. Remember that a major scale consists of the following steps in succession: whole, whole, half, whole, whole, whole, half.
Playing a scale on one string also helps you become better at smoothly shifting your hands from position to position. Strive to play the scale as cleanly as possible, so it sounds like you’re playing it on multiple strings in one position.

Get that whole-step/half-step pattern dialed into your head!
Next, here’s a three-octave G-major scale showing one fingering for the ascent and another fingering for the descent. Also, try playing both fingerings ascending and descending. Your practice on the exercise above will help make this easier Also, notice that the rhythm in the three-octave exercise is triplets. Try accenting the beginning of each triplet to help you with the rhythm.

Next, try the following exercise which features sequenced G major sextuplets. This particular exercises can be a pain for many guitarists. Why? Well, most guitarists are pretty lazy! Notice the arrows in the exercise below? This is where guitarists tend to take a shortcut. Because the C-natural and the F-sharp form the tritone (the Devil’s interval, they say), the fingering becomes a little awkward when playing the three sextuplets that are affected. Most guitarists will either substitute a C-sharp for the C-natural, which hints at the key of D Major, or an F-natural for the F-sharp, which hints at C Major – but don’t you do it!
The tritone, by the way, is considered to be the most unstable interval in Western music. Just play them together and you’ll hear. This interval is what gives diminished triads and arpeggios their quality, which has been exploited endlessly by metal guitarists! Just play the low E-string, 8th fret (the C-natural) with the A-string, 9th fret (the F-sharp). That sound is the tritone interval.
The first instance of this interval is shown by the arrows below:

To further help reinforce the shapes, here are two more self-explanatory G-major scale exercises all on the high E-string. The first one uses the pedal point technique, common in the Baroque era and made popular by Yngwie. Pay attention to the slight change in the last four sixteenth notes.

This last exercises is very similar to the pedal point exercise. It includes both ascending and descending versions. Pay attention to the similarity to the very first E-string only exercise.
