Find chords, remove vocals and practice with free music tools

Full Partituras Studio is a free set of music tools from Full Partituras, the sheet music site. Find the chords of a song with Chord AI, take the vocals out or split it into stems, and practice with the tuner, the metronome, scales and the fretboard.

You don't need an account. The tools that process audio on our server take files up to 30 MB and songs up to 5 minutes long; everything else runs in your browser.

AI tools for the audio of a song

Chord AI works out the chords of a song from the audio, along with its key and tempo, guitar, ukulele and piano diagrams, and the progression as a MIDI file. To prepare a track, use the vocal remover to keep the instrumental, or the stem splitter to get 6 tracks: vocals, drums, bass, guitar, piano and other.

The separation is done by Demucs, Meta's open-source neural network. Our server has no graphics card, so allow a few minutes: removing the vocals from a 5-minute song takes about 7, and splitting it into 6 stems about 8. The song key finder tells you what key a song is in, and the BPM detector measures its tempo without uploading the audio.

Theory and practice, nothing to install

To study, there are guitar chords with 102 chords and their voicings, a chord namer that tells you which chord you are holding on the fretboard, the guitar modes on the fretboard and the piano, the chords in every key around the circle of fifths, and the Indian ragas.

To practice, there is a guitar tuner with an adjustable reference pitch, a metronome with subdivisions, an interval recognition game, a backing track generator and MIDI chord progressions. All of these run in your browser, with nothing to upload.

Free, no account, still in testing

The Studio is in a testing phase: there are no ads and some tools may change. If something breaks or you have an idea, press “Send feedback” and tell us.

It is based on Guitariz, an open-source project by Abhinav Vaidya under the MIT License, which Full Partituras has adapted and translated. More in About.

Frequently asked questions

What is Full Partituras Studio?

A free set of music tools from Full Partituras, the sheet music site. Use it to find the chords of a song, remove the vocals, split a song into stems and practice with a tuner, a metronome, scales and chords.

Do I have to pay or create an account?

No. Every tool is free and none of them asks you to sign up. There are no ads during the testing phase either.

Which tools run on your server and which run in my browser?

Chord AI, the vocal remover, the stem splitter and the song key finder send the audio to our server for analysis. The BPM detector, the tuner, the metronome, the chords, the fretboard, the scales, the interval game and the backing tracks run in your browser.

What are the limits for the songs I upload?

Files up to 30 MB and songs up to 5 minutes long. When there is a queue, songs are processed one at a time, so you may have to wait a moment.

What happens to the audio I upload?

It is processed on our server and never shared with anyone. The original is deleted as soon as processing ends, and the tracks we create can be downloaded for one hour; after that they are deleted automatically. The details are on the privacy page.

Can I use it on my phone?

Yes, it works in the browser of your phone, tablet or computer. You can also install it as an app with “Install app”, but offline only the pages you have already visited will open, and the tools that use our server need an internet connection.
