Now looking at the fretboard we have located all the C notes by following the patterns described above. This pattern repeats up and down the fretboard for every note. Take a pen and draw a circle around the patterns as described. By learning the patterns you can quickly jump from any note.
Pattern 1: 2 and 5 string, two frets apart (i remember it as 25-2)
Pattern 2: 5 and 3 string, two frets apart (i remember it as 53-2)
Pattern 3: 3, 1 and 6 strings, three frets apart (316-3)
Pattern 4: 1, 6 and 4 strings, two frets apart (164-2)
Pattern 5: 4 and 6 string, three frets apart (46-3)
Notice how the ending note/string of the previous pattern begins the second pattern? i.e. Pattern 1 ends on 5th string/3rd fret and Pattern 2 begins there, n the 5th string/3rd fret. That is one complete octave, from C to C.
Circle the patterns as I have listed them above, and you will see what I mean. It is a visual. You have to see it to understand what I am talking about.
