Recommended Free Tools
To create vocal harmonies with AI, start with a clean lead vocal, decide which notes the backing parts should sing, then generate or convert those parts and mix them under the lead. For a direct harmony-making workflow, Audimee explicitly offers a harmony maker for up to five harmony tracks. Revocalize AI lists vocal harmonies, and VOCALOID6 lists harmony creation. Their entries do not establish that they use the same input method, accept the same prompts, or suit every musical style, so check each vendor’s workflow before choosing.

These are the clearest fits in the available product information. It does not establish whether any of them has a dedicated harmony prompt box, which genres they handle best, or whether a particular phone or tablet is supported. Check the vendor’s site for those specifics. Audimee is web-based; VOCALOID6 is desktop software for Windows and macOS. Revocalize AI lists a VST plugin and support for Logic Pro, Ableton and FL Studio.
Plan The Harmony Before Generating It
Harmony is a set of different sung notes that support the lead, not simply a second copy of the same vocal. Decide where the backing voices enter, which lyric syllables they sing, and how they move against the melody. Keep the lead’s words and rhythm easy to follow, and leave room for the lead to remain prominent.
For a concrete starting arrangement, imagine a four-bar phrase in C major. Keep the lead melody as recorded. Have one backing part enter only on the final two bars, singing sustained notes a third above the lead where those notes fit the chord. Add a lower part on the final held word, using a chord tone below the lead. This is a musical plan to try, not a claim that a tool will infer these notes from a text prompt. Check every generated note against the melody and chord progression.

Create The Vocal Harmony
- Prepare the lead. Record or import the lead phrase you want to harmonize. Trim silence, listen for noisy or unclear sections, and use a consistent phrase so you can compare the lead and harmony together. The product listings do not specify required audio formats or recording settings; check the chosen tool’s instructions.
- Mark the harmony entrances. Write down the exact bars or words where each backing part should begin and end. Start with one harmony line. Add another only where the arrangement needs it.
- Choose a workflow that matches your source. With Audimee, look for its harmony maker and set up no more than five harmony tracks. With Revocalize AI, use its listed vocal-harmony workflow and pitch controls. With VOCALOID6, work from melody and lyrics and use its listed harmony-creation feature. The listings do not specify the exact controls or steps inside these workflows, so follow the current vendor instructions.
- Check the notes and words. Play each harmony against the lead. Correct notes that clash with the chord or obscure the melody, and listen for lyric syllables that no longer line up. Do not assume that an AI-generated part is musically correct just because it sounds polished on its own.
- Balance the parts. Keep the lead clear, then set the backing levels so the harmonies support rather than compete with it. The available product information does not establish specific mixing controls, export formats or stem options for every tool; check the vendor’s documentation if you need separate files for a DAW.
Choose A Different Approach If You Need Sung Parts From Scratch
If you do not have a recorded lead, VOCALOID6 is the most clearly documented fit here for building singing from melody and lyrics, with harmony creation also listed. Revocalize AI and Audimee are described primarily around vocal transformation and harmony processing; their entries do not establish a full lyrics-to-harmony generation workflow. LyricToMelody AI generates melodies and sung vocal drafts and exports MIDI, audio and separate stems, but its listed details do not explicitly confirm harmony-generation controls, so verify that feature before relying on it for this task.
