What transposing means
Transposing a song means moving every chord up or down by the same distance, so the song keeps its shape but sits in a different key. If a song is too high for your voice in G, moving it down two semitones to F makes every note two semitones lower, and the melody still sounds like the same tune. The tool does this for every chord in your chord sheet at once.
How to use the transposer
- Paste your chord sheet into the left box. Put chords on their own line above the lyrics (the usual chord-sheet layout) or inline in square brackets like
[G]Amazing [C]grace. - Move the slider or press −1 / +1. Each step is one semitone, which is one fret on the guitar.
- Or pick a target key from go to key, and the tool works out how many steps to move.
- Copy the result, or press Use as input to keep working from the new version.
Lyric lines are never touched. A line is treated as a chord line only when every word on it is a chord or a symbol such as |, x2 or N.C., so a lyric line that starts with “A” stays as it is.
Sharps or flats?
The same pitch can be written two ways: A# and Bb are the same fret. With Automatic spelling, the tool looks at the destination key and uses the spelling musicians expect: flats for keys such as F, Bb, Eb and Dm; sharps for G, D, A, E and so on. You'll get Bb in the key of F rather than A#, which is much easier to read.
The 12-step cycle
There are only 12 different notes before the pattern repeats an octave higher:
C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B (C)
Notice there is no sharp between E and F, or between B and C. Moving +12 or −12 brings you back to the same chords, which is why the slider stops at 11.
Transposing vs using a capo
Transposing changes the chord names; a capo changes the pitch while you keep the same shapes. If a song is written in Eb and full of barre chords, you can capo the 1st fret and play D shapes instead — or capo the 3rd fret and play C shapes. The capo calculator finds the easiest option automatically, and our guide on transposing songs walks through the theory with examples.
Chords the tool understands
Major and minor chords, sevenths (7, maj7, m7), suspended and added chords (sus2, sus4, add9), extended chords (9, 11, 13), diminished and augmented chords, half-diminished (m7b5) and slash chords such as D/F#, where both the chord and the bass note move.
Frequently asked questions
How many semitones should I transpose for my voice?
Sing the highest part of the chorus. If you strain, go down one or two semitones and try again. If the verse is too low and mumbled, go up. Most people find a comfortable key within three semitones of the original.
Will it keep chords aligned over the lyrics?
Yes. Each new chord is placed at the same column as the original. If a chord gets longer (for example C becomes C#m), the following chords shift only as much as needed to keep one space between them.
Does it work with ChordPro format?
Yes. Chords written inside square brackets, like [Am] or [G/B], are transposed in place.
What is the difference between a semitone and a whole tone?
A semitone (half step) is one fret. A whole tone (whole step) is two frets. Moving from G to A is a whole tone, so +2 on the slider.
