What is in each of the six stems
| Stem | Contains | How clean it usually is |
|---|---|---|
| Vocals | Lead and backing vocals | Strong |
| Drums | Kit and most percussion | Strong |
| Bass | Bass guitar, synth bass, sub | Strong |
| Guitar | Acoustic and electric guitar together | Good on clear arrangements, rough on crowded ones |
| Piano | Acoustic piano and similar keys | Good when the piano is prominent; organs and pads often go to other |
| Other | Synths, strings, brass, pads, effects | Whatever the five above did not take |
The six-stem model is separate from the four-stem one, and its guitar and piano outputs are its weakest. If you only need vocals, drums or bass, the 4-stem option is cleaner. Choose 6 stems when guitar or piano is what you are after.

This is the engine's output on Sunlight, a song we generated ourselves. The players show the four-stem split; the six-stem split adds guitar and piano files in the same format.

What to do with guitar and piano stems
- Learn a part: loop the guitar or piano stem and slow it down in any player.
- Play along: mute the guitar stem by summing the other five, and play the part yourself.
- Find the chords: run the stem through the chord finder, which is easier on an isolated instrument.
- Remix: keep the piano and vocals, and replace the rest.
Frequently asked questions
What are the 6 stems?
Vocals, drums, bass, guitar, piano and other. Other holds everything the first five do not, such as synths, strings, brass and effects.
Is the 6-stem splitter free?
Yes. You get 1 fast 6-stem split a day for songs up to 10 minutes, with no sign-up. After that each started 5 minutes costs 30 credits.
Can I split 6 stems in my browser without uploading?
Not yet. The in-browser mode runs the 2 and 4-stem model, unlimited and free for songs up to 8 minutes. The 6-stem model runs on our server.
Which model does the 6-stem split use?
Demucs htdemucs_6s from Meta AI Research, the six-source version of Demucs. It is the same family used by Ultimate Vocal Remover's Demucs option.
Why does the guitar stem sound rough?
Guitar and piano share frequencies with each other and with synths, so they are the hardest stems for any model. Clear arrangements with one guitar split well; dense rock mixes with several guitars and keys often do not.
Is this a free alternative to Moises for guitar and piano?
For separating, yes: you get guitar and piano stems as downloads without an account. Moises adds a practice player, chord display and mobile apps, which TuneSplit does not have.
Can I split electric and acoustic guitar apart?
No. All guitars go into one guitar stem. The model does not separate lead from rhythm or acoustic from electric.
