Major to Minor Key Converter

A major to minor key converter rewrites only the notes that make a key sound major. In C major, the chords C G Am F become Cm Gm A♭ Fm in the parallel minor (C minor) or Am Em F Dm in the relative minor (A minor). Minor to major works the same way in reverse.

Why not just pitch-shift the song? A pitch shift moves every note by the same amount, so a major song stays major. Minor needs only some notes changed (the 3rd, 6th and 7th), which is what the chords above do.

How to change a song from major to minor

1. Find the key. The first and last chord usually name it (a song that starts and ends on G is in G major). Not sure? Open the song in the tool’s song section, or read how to find the key of a song.
2. Choose parallel or relative. Parallel keeps the key note (G major → G minor) and sounds like the same song turned dark. Relative keeps the notes (G major → E minor) and moves the home chord.
3. Type or tap the chords (for example G C D Em). The tool marks every chord that changes and names the reason under More options.
4. Play the original and the converted version to hear the difference, then copy the result into your chord sheet.
5. Change the melody too. Switch to Melody notes: every 3rd, 6th and 7th of the key drops a semitone (B → B♭ in G minor). Singers only change those notes; the rest of the tune stays.

Example: the I–V–vi–IV progression in C major (C G Am F) becomes Cm Gm A♭ Fm in C minor. With harmonic minor the V chord stays G major (Cm G A♭ Fm), which pulls back home more strongly and is how many minor songs end their phrases.

Parallel minor vs relative minor

The parallel minor has the same key note; the relative minor has the same notes. C major and C minor share the tonic C but differ in three notes (E♭, A♭, B♭). C major and A minor share all seven notes and key signature, but A becomes home. That is why a relative conversion keeps the chords’ positions in the scale (I → i, IV → iv, V → v) and moves them down a minor third, while a parallel conversion keeps the chord roots and changes their colour.

C major: parallel vs relative minor

	Parallel minor	Relative minor
C major becomes	C minor	A minor
Key note (tonic)	Same: C	Down a minor third: A
Notes that change	E → E♭, A → A♭, B → B♭	None: same seven notes, new home note
C G Am F becomes	Cm Gm A♭ Fm	Am Em F Dm
Sounds like	The same song in a darker mood	A related song in a lower, sadder key
Common in	Borrowed chords (A♭, B♭, Fm in a major song), film cues, the popular “major to minor” remakes	Verses in the relative minor, key changes inside a song

The circle of fifths shows every relative pair at a glance (the inner ring), and the music key chart lists each key’s notes. For what a key is in the first place, see what is a song key.

Which notes change: the 3rd, 6th and 7th

Only three scale degrees separate major from minor. A major scale is built whole, whole, half, whole, whole, whole, half. The natural minor lowers the 3rd, 6th and 7th by one semitone (written ♭3, ♭6, ♭7). The 3rd matters most, because it decides whether the home chord is major or minor; harmonic and melodic minor keep the raised 7th (and melodic the 6th) to make the melody lead home.

Scale degrees that change (C as the example)

Degree	1	2	3	4	5	6	7
C major	C	D	E	F	G	A	B
C natural minor	C	D	E♭ (♭3)	F	G	A♭ (♭6)	B♭ (♭7)
C harmonic minor	C	D	E♭	F	G	A♭	B
C melodic minor	C	D	E♭	F	G	A	B
Chords, major key	I	ii	iii	IV	V	vi	vii°
Chords, natural minor	i	ii°	III	iv	v	VI	VII

What happens to each chord: every chord that contains one of the changed notes changes quality. The I, IV and V chords turn minor, ii turns diminished, and iii, vi and vii° become major chords built on the lowered notes (E♭, A♭, B♭ in C minor). Chords outside the key, such as a D major in C, keep their type; only a root that is a 3rd, 6th or 7th of the key moves. Semitones are explained in what are semitones.

Find your major key in the left column. The chords are listed in scale order (I ii iii IV V vi vii°), so the fifth chord of each row is the V: in harmonic minor it stays major (G in C minor). The same chart read from right to left converts minor to major.

Minor to major: the same steps in reverse

To turn a minor song major, raise the ♭3, ♭6 and ♭7 by a semitone. A minor (Am F C G) becomes A major (A F♯m C♯m G♯°) in the parallel major, or C major (C Am Em B°) when the chords keep their positions in the relative major. Chords that already use the raised 7th, like E or E7 in A minor, stay as they are. In the tool, choose Minor → Major; the key menu then lists minor keys.

Can you convert an audio file from major to minor?

Not with a pitch shift. A pitch shifter, or any online pitch changer, moves every note by the same interval, so C major shifted down 3 semitones becomes A major, still major. Turning a recording minor means lowering only the 3rd, 6th and 7th wherever they sound, inside chords and harmonics. That is note-level editing: software that separates each note of a mix can do it on clean recordings (a solo instrument or voice works best), and the “AI” converters mostly work this way, with audible artefacts on full songs.

What works in practice: play or sing the song with the converted chords from the tool; for a backing track, replay it in minor or use a MIDI version. The song section finds the key of your audio so the chords fit, and it can shift the whole song with the tempo kept, for example to sing it lower. For key changes of whole songs, the guide to changing the key of a song and key change vs pitch change explain the options; the MP3 pitch changer handles several files at once.

Questions about major and minor keys

Is C major the same as A minor?

They use the same seven notes, but they are different keys. A minor is the relative minor of C major: same key signature, no sharps or flats, but A is the home note, so the same chords sound darker. C minor, the parallel minor, has three flats.

What is the minor of C major?

It depends on which minor you mean. The parallel minor of C major is C minor (C D E♭ F G A♭ B♭); the relative minor is A minor (A B C D E F G). Songs that go “from major to minor” on the same key note use the parallel one.

Is there an AI that converts a song from major to minor?

Some tools try it by editing each note of the recording, which works on clean solo parts and leaves artefacts on full mixes. No pitch shift can do it, because it moves all notes together. Converting the chords and melody here, then replaying them, gives a clean result.

How do I turn a major scale into a minor scale?

Lower the 3rd, 6th and 7th notes by one semitone. G major (G A B C D E F♯) becomes G natural minor (G A B♭ C D E♭ F). For harmonic minor keep the 7th (F♯); for melodic minor keep the 6th and 7th.

Does converting to minor change the tempo or key note?

No. The tempo is never touched, and a parallel conversion keeps the key note (G major → G minor). A relative conversion moves the home note down a minor third (G major → E minor) while keeping all the notes.

Can I convert an MP3 from major to minor?

Not automatically without artefacts. Open the MP3 in the song section: the tool detects its key and gives you the minor chords to play over it, and it can shift the whole MP3 by semitones (tempo kept) and save it as WAV or MP3.
