Guitar Scales and Theory
Understanding the fretboard
I've tried to keep this as simple as possible. Memorise each diagram as you go for the best results. The headstock of the guitar is at the top, where the thick line is.
The musical alphabet runs: A B C D E F G, then A again, but one octave higher in pitch.
Although musical notes follow the alphabet, the flats and sharps complicate things. Just remember there are no flats or sharps between B and C, E and F. All the other notes have them. Fret 2 on strings 1 and 6 could be called F sharp or G flat depending on your whim.
A A♯ B C C♯ D D♯ E F F♯ G G♯ A - using sharp notes
A B♭ B C D♭ D E♭ E F G♭ G A♭ A - using flat notes
- A, B, C is the same place on strings 1 and 6
- D, E, F is the same pattern, but over on the 5th string
Octaves - something to do with 8, right? There are 8 notes in a major scale (though only 7 different ones) and the last box shows an octave A. Using the 6th string A, you can work out where the next A note will be by using this interval. Then it'll work for all the other notes - look at the D octave example.
That's a great thing about the guitar world - things are easily transferable all over the fretboard.
A5 is shown - for B5 move up 2 frets, for C5 up one more fret, etc. These are also known as power chords, widely used in rock and grunge. Possibly used too widely.
On the right hand side I've named all the notes in sequence - this sequence is the same, regardless of where you start on the fretboard.
Note that all the sharp named notes could be called by flat names too.
The most common scale in rock - use for anything in Am and also C major. If the song has C, F, G7 in it this will work.
A to B is a 2 fret interval - so move this pattern up 2 frets and you will have Bm pentatonic. Use over D, G, A7
B to C is a 1 fret interval - so up another 1 fret gives you Cm. Use over Eb, Ab, Bb7, or Cm7, Fm7, Gm7.
Pentatonic literally means "5 notes". You are using the same notes as the major scale, but subtracting two of them - the two that can be difficult to use due to clashes with chords.
My new hub on pentatonic scales has a complete neck diagram for the scale patterns.
E major scale
The last chart shows the E major scale. You can transfer this pattern to all the other strings, and you will get the major scales that start from whichever note you start from - so using E A D G B E, the open string notes, you can play G major on string 3, D major on String 4, A major on string 5.

- Playing scales up and down the neck rather than across it has some real advantages.
- You can see intervals between the notes more clearly
- By using pull offs you can dramatically improve speed without much effort
- You may find that finger strength is improved.
If you are playing around the fret 12 area - remember than fret 12 is the same as the open string in terms of notes. So counting down from fret 12 is very, very useful - on string 5 (A) you could count down 2 to find G, down 1 to find A flat, etc.
Practice tips: Try playing in short but concentrated sessions. Even 10-15 mins several times a day will really help you progress. I'll also be playing while watching TV.
