The following is an excerpt from my “Hello Guitar” Guide to Getting Started

* Note: occasionally in this post, you will see a lower case “b” next to a note name. This means that the note is “flat.”

Given any note or chord, there are only five positions on the guitar neck from which it can be played. This is an incredibly useful tool considering that there are over 3,500 chords and over 550 different scales that can be played on the guitar. Yet, everything you will ever do on the guitar boils down to understanding these five simple positions. These are the five positions from which a given root note is played with at least one other octave. (Root notes are the notes that define a chord or scale at its foundation. For example, in the C Major chord, the root note is the note C, from which, the rest of the chord gets its name.) In this book, I have labelled these as positions one through five. Add them to your warm-up routine and spend as much time as needed to get familiar with them. We’ll be using these positions quite a bit throughout this book as we learn how to construct numerous scales and chords. Position 1 occurs when the root note is located on the top, bottom, and fourth string. 

Helpful Tips for position 1:

• There is one fret in between the root notes on the first and sixth strings and the root note on the fourth string.
• There is one string in between the root note found on the 6^th string and the root note found on the 4^th string
• There are two strings in between the root note found on the 4^th string and the root note found on the 1^st string.
• The notes on the top and bottom string of a fret are always the same root note.
• In the open position, the notes E, F, and F# occur in position 1
