Guitar Fretboard Basics - How the Fretboard Works

Let's begin the theoretical side of our guitar learning journey with some essential fretboard basics.

As a beginner guitarist, it'll likely be your first proper theory lesson (don't worry, it's easy!) and should come before you move on to learn chords, scales and technique.

It's important to get to know the fretboard because doing so will help you understand the relationship between finger positions, strings and notes when you come to playing chords and lead guitar. As with a lot of guitar theory, you only realise how important it is once you've learned it.

So let's learn it now!

Fretboard Basics #1 - Frets and Inlays

Your guitar's fretboard has a sequence of raised metal wires called frets. Most electric guitars have 21, 22 or 24 frets and acoustics tend to have 20.

fret numbers

Each fret represents a new note for each string, but when we come to press our fingers on the fretboard, we actually use the spaces in between the fret wires to create the note, not the wire itself.

fret space, wire and fingering position

For example, pick any fret and the space before that is the area that creates the note when applying our fingers.

So when we refer to the 2nd fret or 6th fret we are actually referring to the space just before the actual fret wire. Because of this, guitarists tend to think of "frets" as the spaces rather than the wire.

You'll notice on your guitar's fretboard there are inlay markers, either dots or symbols at particular fret intervals. Most commonly, these are found at frets 3, 5, 7, 9 and 12.

The 12th fret marker is often more prominent than the others (e.g. 2 dots instead of 1). We'll see why the 12th fret is particularly significant in a minute.

Once we get beyond the 12th fret, the pattern of inlays repeats itself. So, the inlay markers will be at frets 15, 17, 19, 21 and 24 if your guitar accommodates it.

It's a good idea to learn these inlay positions and their corresponding fret numbers to start with (that was a hint!).

Fretboard Basics #2 - Open Strings & Octaves

Your guitar will most likely have 6 strings (sorry, this site doesn't cover guitars with 7 or more strings... yet!).

From low to high (low being the lowest sounding, fattest string) we have:

E A D G B and e (small "e" representing the higher pitch).

This is known as standard tuning and is by far the most common guitar tuning.

Playing any of the strings without pressing any fingers on the fretboard is known as playing the string open. So an open string is basically an unfretted string (e.g. open E, open A, open D etc.).

Now, here's where the 12th fret comes in - if you play any of the 6 strings open, then press that same string at the 12th fret, you get the same note but what is called an octave higher. This means the equivalent of "12 frets higher" or "12 semitones higher".

open strings and 12th fret octaves on the fretboard

You will better understand why this is as you progress, but in short there are 12 notes in total in the musical alphabet. Once you get passed the 12th note, the alphabet repeats, with the higher pitched octave notes. More on this another time!

If your guitar has 24 frets, the 24th fret will be an octave higher than the 12th fret, and therefore two octaves higher than the open string!

This also means that notes/frets past the 12th fret will be an octave higher than their corresponding lower fret for each string.

For example, the 13th fret is an octave of the 1st fret for each string. The 17th fret is an octave of 5th fret. Try and learn all the corresponding octaves past the 12th fret as you'll be referencing these all throughout your guitar playing life.

We'll be looking more at what we actually call the notes in between the open - 12th fret - 24th frets in a later fretboard lesson. For now, though, just ensure you can identify the open strings, the fret numbers and their octaves beyond the 12th fret.

Numbering your frets is also beneficial when it comes to reading guitar tab (a form of notation for guitar), it will show you at which fret numbers you need to press your fingers for each string.
