How to Read Guitar Chord Charts, Chord Sheets and Tabs

By Wikum · August 8, 2026 · 4 min read · Beginner

Most songs online are written in one of three ways: chord diagrams, chord sheets (chords above lyrics) and tablature. None of them requires reading standard music notation, and you can learn all three in an afternoon. This guide explains each one, plus the symbols that confuse beginners most.

Chord diagrams

A chord diagram (or chord box) is a picture of a small part of the fretboard, viewed with the guitar upright facing you.

• Vertical lines are strings: low E on the left, high E on the right.
• Horizontal lines are frets. A thick top line is the nut, meaning the diagram starts at the very first fret.
• Dots show where to press. Some charts put finger numbers in them: 1 index, 2 middle, 3 ring, 4 pinky (T for thumb).
• ○ above a string means play it open. × means don't play it or mute it.
• A curved line or bar across several strings is a barre: one finger presses them all.
• A fret number beside the box (like 2fr or 5fr) shows where the diagram starts when it's higher on the neck.

Chords are also written as a six-character code from low E to high E: 320003 is G, x24432 is Bm. The chord finder shows both forms for any chord.

Chord sheets

A chord sheet puts chord names above the lyrics, exactly over the syllable where the change happens:

G                 D
  I walked along the river
Em                C
  And the water sang to me

Change to the chord when you sing the syllable under it. If a line has no chords, keep playing the last chord. Many sites write chords inline in brackets instead — [G]I walked along the [D]river — which is called ChordPro format.

Understanding chord names

Slash chords

A slash chord such as D/F# means: play a D chord but put F# in the bass. They usually create a smooth walking bass line, for example G – D/F# – Em, where the bass goes G, F#, E. If a slash chord is too hard at first, just play the chord before the slash. You'll lose the bass movement but the song will still work.

Song structure and repeat symbols

• [Intro], [Verse], [Chorus], [Bridge], [Outro] label sections. A chorus is usually written once and then referenced again.
• x2, x4 after a line means repeat it that many times.
• | G | D | Em | C | — bars separated by vertical lines. Each bar is usually four beats.
• N.C. means “no chord”: stop playing, usually while the singer has a solo line.
• G / / / — each slash is one beat of the chord.

Reading guitar tab

Tablature shows single notes and riffs. Six horizontal lines are the six strings, but with the high E at the top — the opposite of how you might expect. Numbers are frets to play, read from left to right.

e |-------0-----------|
B |-----1---1---------|
G |---0-------0-------|
D |-2-----------2-----|
A |-3---------------3-|
E |-------------------|

This example is the notes of a C chord picked one at a time. Numbers stacked vertically are played together. Common symbols: h hammer-on, p pull-off, / slide up, \ slide down, b bend, x muted note.

Tab doesn't usually show rhythm, so listen to the recording to hear how long each note lasts.

When the key doesn't suit you

Chord sheets are often written in the original recording's key, which might be awkward for your voice or full of barre chords. Paste the sheet into the chord transposer to move it, or use the capo calculator to keep easy shapes.
