Now you understand how the tuning of the guitar effects chord shapes lets take it a step further. We will learn how to look for the patterns, keeping in mind that the B string affects the "symmetry" of the shapes and patterns.
Lets start with finding the note G in all locations on the fretboard:
Lets break it down into smaller chunks, boxes or patterns if you will. Also notice the fret spaces and string gaps between the pattern shapes.
*Note: the patterns repeat themselves after the 12th fret
Notice how shape 1 & 4 look the same:
Notice how shape 2 & 5 also look the same:
Notice how shape 3 & 7 also look the same:
*shapes 2 & 5 would look the same as 1 & 4 if it wasn’t for the tuning discrepancy between the G & B string mentioned in the previous section*
There are really only 4 unique shapes:
You can use this method to find all the locations of a single note across the fretboard. Think of it as a fretboard roadmap. Try out the exercises below:
Can you see the patterns?
I recommend learning the notes on all strings, however learning all the natural notes along the Low E and A strings and then using the shapes to find out where they are located on the rest of the strings would be a good start. By memorising the notes on the Low E you have also memorised the high E string.):
And if you memorise notes on the A string, thats three strings, you're halfway there:
The enharmonic notes (the black keys on a piano (#/b)) are in the spaces and if you want to find for example, the note ‘Gb’, it will be before the note G and after the note F:
Good luck! I hope you have found this useful. Let me know in the comments.
