Fretboard Basics
How the fretboard is organized
Learn how strings, frets, and standard tuning combine into a repeatable note map.
Strings are starting notes
In standard tuning, each open string starts from a fixed note: low E, A, D, G, B, and high E.
Every fretted note is counted upward from that open string one semitone at a time. The fretboard looks wide, but it is built from one small rule repeated many times.
Frets move by half steps
Moving one fret higher raises the pitch by one half step.
After twelve frets, the same note name repeats one octave higher. That means the twelfth fret is a checkpoint, not a mystery.
Use the low E string as a ruler
Play the open low E string, then frets 1, 2, and 3. You are hearing E, F, F#, and G.
Repeat the same idea on the A string: open A, then A#, B, and C. The note names change, but the half-step rule does not.
Use the idea on your guitar
Walk one string slowly
- Play the open low E string, then frets 1 through 5 one at a time.
- Say the note names out loud as E, F, F#, G, G#, A.
Listen for: Notice that each fret sounds like the smallest possible upward step.
Single-string riffs
Reference: Many beginner rock and blues riffs
A lot of familiar guitar parts begin by moving a small number of frets on one string. You do not need the exact riff to learn the idea: adjacent frets create tight motion, while skips create a bigger jump.
When a song moves a shape up one fret, it is using the same half-step logic you just played.
Write a one-string idea
Create a four-note idea on the low E string using only frets 0 through 5.
- Start and end on either open E or fret 5 A.
- Play it twice, then change one note by one fret and listen for the difference.
Before you move on
- What happens when you move one fret higher?
- The pitch rises by one half step.
- Why is the twelfth fret useful?
- It repeats the open string note name one octave higher.
