One pain in playing the guitar is finding out where notes lie on the fretboard. Well, it’s a pain no longer! With this method, you can locate any note in all its positions easily. The first step is to memorize the notes on the 6^th and 5^th strings. (C’mon, you have to do some work..). This is very easy:

6^th String notes: (E open) F F# G G# A A# B C D D# E F …..

5^th String notes: (A open) A# B C D D# E F F# G G# A A# …..

Now just memorize the layout of the following triangles:

Diagram I: Strings 6, String 4 and String 1
Here, the orange boxes mark the location of the same note in different places.
In this case all the notes are: G

Diagram II: Strings 5, String 3 and String 2
Here, the orange boxes mark the location of the same note in different places.
In this case all the notes are: D

This shortcut method can save some time and is the foundation for playing octaves.
