  • Swap style tags or use Inspiration for a fresh stack

  • Lock the take that leaves space for the voice

  • Upload a dry vocal stem or library vocal-only take
  • Describe the new production direction in style text
  • Choose Keep vocals or Backing only for your next edit
  • Use Vocal Remover or Stem Splitter when you need extraction instead

Creator workflow notes

Creator notes from the Add Instrumental workflow

How creators may use upload, style tags, and output modes in a session—not perfect every time, but clear enough to keep demos moving.

"Uploaded an a cappella and kept vocals on. First pass felt busy, so I swapped the style tags and the second backing sat better under the phrasing."

"Voice memo plus piano style—usable draft, still needed my own EQ pass."

"Dropped a spoken-word take under a trap-leaning style. Groove followed the lines, but the 808 crowded the midrange a bit 🔥"

"Chose Backing only, left lyrics empty, and pulled an instrumental into my DAW. Took a couple minutes after the 3-credit submit—cleaner than building a scratch bed from scratch."

"Same vocal, Inspiration for lo-fi then rock. Third pass was the keeper 🎙️"

"Used a dry stem after separation and generated a new arrangement—not an extracted instrumental. Backing was solid, still needed EQ before a client send."

Add Instrumental FAQ

Frequently asked questions about Add Instrumental

Straight answers on uploads, credits, output modes, timing, and how this differs from Vocal Remover.

Add Instrumental to Vocals is MusGen’s tool for generating new backing around a vocal you already have. Upload an a cappella or vocal track, set style tags, and create accompaniment—unlike Vocal Remover, which extracts parts from a finished mix.

Upload an MP3/WAV vocal or pick one from My library, enter a title, choose Instrument/Style, pick Keep vocals + backing or Backing only, then generate after login. Optional lyrics are available when you keep vocals.

You can use Add Instrumental online after you log in and have credits. Each successful generation costs 3 credits. Online Free in the title means you can try with available credits—not unlimited free downloads or commercial rights.

Yes. Choose Backing only in output options to return the new instrumental without your vocal. Use Keep vocals + backing when you want a full mix.

The model aims to generate backing that follows your vocal timing and phrasing from the reference audio. There is no separate Key or BPM lock control—results vary with the clarity of your take and the style you choose.

Upload an MP3 or WAV vocal audio file up to 50MB, with reference audio up to 8 minutes. Clean a cappella, rap, or spoken-word takes work best. You can also select a vocal from My library.

It depends on your workflow. MusGen Add Instrumental is built for vocal-conditioned demos with style tags and Keep vocals / Backing only modes. Compare credit cost, output quality, and whether you need extraction tools instead.

No. Add Instrumental creates new backing under your vocal. Vocal Remover and Stem Splitter separate parts from an existing mix. Use extraction tools when you need stems; use this page when you need a new arrangement.

AI accompaniment for sung melodies here means generating drums, harmony, and arrangement around a sung or spoken vocal reference you provide—guided by style tags—not a free-standing practice track with no vocal upload.

Yes. Style tags can steer piano style backing, acoustic guitar style, lo-fi backing, or a rock band instrumental on the same vocal. Tags guide mood and arrangement; they are not separate instrument-only controls.
