The G major Diatonic Scale

The diatonic scale is a very important one on guitar. Like any other diatonic scale, it is composed of 7 notes. For this lesson, we are going to take a look at the G major diatonic scale.

Constructing a diatonic scale is simple. Following the alphabet, you just pick a letter from A to G. Based on the pattern of tones and semitones in between notes ABCDEFGA which is TSTTSTT (T for tone, S for semitone), you can derive your diatonic scale following this pattern: TTSTTTS.

For this case, the base note of the G major diatonic scale is G. Following the pattern TTSTTTS, it gives you GABCDEF#G which make up your G major diatonic scale.

The best way to play the diatonic scale is to line up one finger per fret. The G major diatonic scale is just within the 2nd and 5th fret. If we are to label frets 2 to 5 as 1 to 4, respectively, we will arrive with this pattern: 2-4, 1-2-4, 1-3-4, 1-3-4, 2-4, 1-2-4.

That completes your G major diatonic scale. The diatonic scale is a great basis for doing your own riffs and slides. Try it yourself.
