How to change the key of a song online

People change the key of a song so that it fits their vocal range: a key that is too high gets lowered, one that is too low gets raised. The same is needed for covers, karaoke, matching another instrument and mixing two tracks in one key.

Everything runs on our server with nothing to install: upload a file, pick a shift from −6 to +6 semitones and get a finished MP3 or WAV. Tempo and length stay the same by default.

A backing track in the right key

To sing a favourite song in a comfortable key you need a backing track without the original vocals. If you do not have one, make it for free from the regular song and shift it right away: after separation a "Change key of the backing track" button is available.

An instrumental takes a shift better than a voice, so you can push a backing track further: 3–5 semitones usually still sounds natural.

How many semitones to shift and what happens to the sound

One semitone is the next key on a piano; 12 semitones make an octave. A shift of up to 2–3 semitones barely touches the timbre. The bigger the shift, the more the character of voice and drums changes, so at 5–6 semitones check the result by ear.

The "like a record" mode (tempo not kept) changes pitch and speed together and adds no processing artifacts — useful when you are fitting a track to your own tempo.

Questions and answers

How do I change the key of a song online for free?

Upload the file on this page, choose a shift from −6 to +6 semitones and press "Change key". In about a minute you can listen to the result and download it as MP3 or WAV. No sign-up needed.

How do I get a backing track in the right key?

First remove the vocals: the separation page ("Vocals + backing track" mode) gives you a separate backing track. Then upload it here and shift it by the number of semitones you need — or press "Change key of the backing track" right after separation.

Does the tempo change when the key changes?

By default it does not: length and tempo are kept, only the pitch changes. If you want the "like a record" effect (tempo changes with pitch), untick "Keep the tempo".

How far can I shift the key without losing quality?

Shifts of up to 2–3 semitones up or down sound good; at 5–6 semitones a vocal may change timbre. A backing track without vocals has more headroom — an instrumental takes a big shift better than a voice.

Can I download the result as MP3?

Yes. MP3 at 320 kbps is the default for MP3 files, and a WAV input comes back as WAV. You can also choose the format yourself.

How do I know how many semitones to shift?

The page detects the current key of the file and shows what it becomes after the shift. To fit a song to your voice, pick the shift that puts the notes you need inside your range.
