How to Transpose Guitar Chords Without Changing the Progression
On this page
To transpose a song, move every chord up or down by the same number of semitones. The progression keeps its shape and feel, and only the key changes. All you need is the list of 12 notes and some care with chord symbols.
The semitone map
In twelve-note equal temperament, an octave contains 12 pitch classes, each one semitone (one fret) apart. After B the list starts again at C.
| Step | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Note | C | C# | D | D# | E | F | F# | G | G# | A | A# | B |
Sharp and flat names can mean the same pitch: C# is Db, D# is Eb, F# is Gb, G# is Ab and A# is Bb. The natural-note pairs B to C and E to F are already one semitone apart. Names such as B# and E# still exist in music theory, but sound like C and F in equal temperament.
To move a chord up, count to the right. To move it down, count to the left. If you run off either end, carry on from the other side.
Step by step
- Decide how many semitones to move. G to A is two steps up.
- Find each chord’s root (the letter name, plus any sharp or flat) in the map.
- Move every root by the same number of steps.
- Copy everything after the root unchanged.
Most mistakes happen at step 4. The root moves, but the chord type stays the same.
Worked example: G, D, Em, C up 2
| Original | Root moves | New chord |
|---|---|---|
| G | G to A | A |
| D | D to E | E |
| Em | E to F# | F#m |
| C | C to D | D |
The song moves from G major to A major. The chords keep the same relationship to each other, which is why it still sounds like the same song.
Keep the chord type intact
Suffixes like m7, sus4 and maj7 stay with the root. Only the letter, and any sharp or flat on it, changes.
| Original | Up 2 |
|---|---|
| Am7 | Bm7 |
| Dsus4 | Esus4 |
| Cmaj7 | Dmaj7 |
| C/G | D/A |
With slash chords, move both parts. In C/G, C is the chord and G is the bass note. Up two semitones, C becomes D and G becomes A, giving D/A. If you only move the first part and write D/G, you get the wrong bass note.
Also watch for chords that look alike. Em7 and Emaj7 are different chords, so keep the exact suffix you started with.
Sharps or flats in the new key
Pick one spelling and use it for the whole chart. Many players use sharps in sharp keys like A or E, and flats in flat keys like F or Bb. The pitches are the same either way, so the choice only affects how easy the chart is to read.
Transposing with a capo instead
A capo raises the pitch without new fingerings. If you want a song to sound two semitones higher, you can keep the original G, D, Em and C shapes and put a capo at fret 2. The capo chart shows what each common shape sounds like from fret 0 to 5.
Both methods rely on the same semitone counting. What a guitar capo is and how to apply one explains why it works as a movable nut. The guitar fretboard notes map shows that each fret is one semitone, so you can check any transposed root right on the neck.
Let the tool do the counting
The capo transposer moves chords for you. It works with lines that contain only chords, and with chords written in square brackets inside lyric lines, such as [G] at the start of a phrase. Before you transpose, make sure every chord in your chart is either on its own line or in brackets. Then check slash chords and suffixes against the rules above.
