Choose the new key, count the interval from the original tonic, then move every melody note and chord root by that same interval. Keep chord qualities and check the result by playing or singing it; shifting a recording is a separate workflow.
To transpose a song, choose a new key and move every melody note and chord root by the same interval. For example, moving from C major to D major is up two semitones: a C–G–Am–F progression becomes D–A–Bm–G. The rhythm and relationships between notes stay the same, while the absolute pitches change.
For a chord chart or score, rewrite or play the notes in the new key. For an existing recording, use pitch-shifting software and listen to the exported result; changing a chart alone does not change the audio file.
Transpose a song in five steps
- Find the starting key. Use a reliable chart, score or careful listening. If the song changes key, identify the sections before applying one global shift.
- Choose the destination. A singer may need a lower or higher range; play through the highest and lowest phrases before settling on a key.
- Count the interval. From C up to D is two semitones; from G down to F is two semitones. A keyboard or chromatic note list helps avoid skipping a half-step.
- Move every note and chord root by that interval. Preserve the chord's quality and extensions: moving Am up two semitones gives Bm, while G7 becomes A7. Move a slash chord's bass note too.
- Play or sing the full passage. Check the melody against the chords, the difficult vocal notes and any accidentals or key changes. Adjust voicings or octave where needed without changing the intended pitches' relationships.
Yamaha's transposition guide explains using scale degrees and chord relationships to move a progression between keys. Its glossary defines transposition as changing a song's key by an interval.
Example: transpose chords from C to D
Count C → C♯ → D: the destination is two semitones higher. Apply the same upward interval to each chord root, keeping major chords major and minor chords minor.
| Original chord | Move root up two semitones | New chord |
|---|---|---|
| C | C → D | D |
| G | G → A | A |
| Am | A → B | Bm |
| F | F → G | G |
So C–G–Am–F becomes D–A–Bm–G. The progression can also be described as I–V–vi–IV in both major keys. If the original contains a chord outside the key, transpose that chord's root by the same interval too; do not silently replace it with a different diatonic chord.
For a slash chord such as C/E, transpose both letters: up two semitones gives D/F♯. The slash note identifies the bass note, so leaving it unchanged can change the intended inversion. Preserve other chord symbols, such as 7, sus4 or add9, unless you intentionally rearrange the harmony.
Count semitones and choose a direction
On a chromatic instrument, adjacent pitches are one semitone apart. In twelve-tone equal temperament, the repeating pitch classes are C, C♯/D♭, D, D♯/E♭, E, F, F♯/G♭, G, G♯/A♭, A, A♯/B♭ and B. E–F and B–C are each one semitone; there is no extra note between those neighboring pairs.
| Starting key | Target key | One possible shift |
|---|---|---|
| C major | D major | +2 semitones |
| G major | F major | −2 semitones |
| A minor | C minor | +3 semitones |
| C major | G major | −5 or +7 semitones, in different registers |
Changing the tonic by a fixed interval preserves major or minor quality: A minor shifted up three semitones is C minor, not C major. Enharmonic names such as F♯ and G♭ can refer to the same pitch on an equal-tempered keyboard, but written notation depends on the key and musical context.
Transpose a recording without changing tempo
- Confirm the source and target. Find the key first if necessary; the key-by-ear guide offers a listening method. The pitch changer does not identify the key for you.
- Choose the semitone shift. Use the interval you calculated. The known-key calculator suggests a nearby shift for tonics you already know; check the direction and register before applying it.
- Prepare a short test. The pitch changer accepts supported mono or stereo MP3/WAV up to five minutes and 50 MiB. Choose the shift, prepare WAV or MP3 and listen to the actual export.
- Check the hard passage. Compare a sustained voice, chord and percussion attack with the original. A mixed file shifts all its sounds together, and processing can change voice character or smear attacks.
This local tool changes the recording; it does not rewrite your chord chart or preserve vocal formants. Follow the recorded-audio key-change guide for output limits, timing and quality checks.
Use a capo on guitar
A capo raises the sounding pitch of open chord shapes. For example, standard-tuning C, G, Am and F shapes with a capo at fret 2 sound D, A, Bm and G respectively. Tell other musicians the sounding key and the capo position, since a guitarist reading shapes and a keyboard player reading concert chords may otherwise play different chords.
A capo raises the shapes relative to the open strings; it does not by itself lower a song. Higher fret positions and different chord voicings can be impractical, so test the arrangement and the singer's range.
Common questions
Does transposing change the song's tempo?
Musical transposition changes pitch, not the intended tempo. Digital pitch shifting can preserve the nominal tempo, but check the exported timing and sound quality, especially against video or other tracks.
Does transposing from major to minor work by moving every note equally?
No. A uniform shift preserves the intervals that make a major or minor passage sound as it does. Changing mode requires altering selected notes or chords rather than moving everything by the same interval.
Can I transpose only the vocal in a mixed song?
A pitch shift on a finished mix affects all sounds in that file. Start with an original separate vocal track when available; source separation from a finished mix is an estimate and should be checked for artifacts and missing detail.
