What you need

Every plan has a limit on how many tracks you can make. When you reach it, wait for it to refresh or upgrade.

  1. Step 1: Open Create music in Gemini

    1 min

    Music lives inside the Gemini chat, so there's nothing to install.

    1. Go to gemini.google.com/music and sign in with your Google account.
    2. Already in a chat? At the bottom of the text box, click Upload & tools, then Create music.
    3. For a full-length track, switch the model to Pro.

    You should see a music prompt box with drop-downs for length, vocals and genre.

    No Create music option?

    Check that your Google account is set to 18 or older and that Keep Activity is on. Some work and school accounts don't offer it, so try a personal account.

  2. Step 2: Set the length, vocals and genre

    2 min

    Background music sits under speech, so a track with no vocals is the safest start.

    1. Pick a length: short runs about 1 minute, full runs about 2 to 3 minutes.
    2. In the vocals drop-down, choose no vocals, so the music won't fight your voiceover.
    3. Pick the genre closest to your video's mood.

    You should see your length, vocal and genre choices set, with the prompt box still empty.

    Full length is missing or won't run?

    Full tracks need the Pro model, which comes with Google AI Pro. If you have it, switch to it in the model menu.

  3. Step 3: Describe the track

    3 min

    Mood, tempo, instruments and structure give Lyria the most to work with.

    1. Paste the prompt below and swap in your own details.
    2. Name 2 or 3 instruments and a tempo. If you skip instruments, Lyria picks ones that suit the genre.
    3. Optional: drag in a clip or a still from your video, so the music fits what's on screen.
    4. Send the prompt.
    Your prompt
    Create an instrumental background track for a [VIDEO TYPE, e.g. product walkthrough] video.
Mood: [calm and focused]. Tempo: about [90] BPM.
Instruments: [soft piano, light electric guitar, brushed drums].
[0:00 - 0:10] Intro: piano alone.
[0:10 - 0:50] Main: add guitar and soft drums, steady and even.
[0:50 - 1:00] Outro: back to piano, ending on a held note.
Instrumental only, no vocals. Keep it low and even so speech stays clear on top.

    You should see a new track in the chat with its own cover art and a play button.

    The track has singing in it?

    Set the vocals drop-down to no vocals, and keep "Instrumental only, no vocals" in your prompt. Then generate again.

    The timed sections follow Google's Lyria prompting docs. For a full track, stretch the times to 2 or 3 minutes.

  4. Step 4: Change one thing at a time

    4 min

    Changing one detail per try shows you what each part of the prompt does.

    1. Play the track next to the first minute of your video.
    2. Change one thing in your prompt, such as the mood, the tempo or one instrument.
    3. Send it again and compare the new version with the first.
    A follow-up to try
    Same track, but slower, about [75] BPM, and swap the drums for soft hand percussion. Keep the piano intro and the held-note ending.

    You should see a second version you can play against the first.

    Gemini says you've hit a limit?

    Every plan caps how many tracks you can make. Wait for the limit to refresh, or move to a higher Google AI plan for more.

  5. Step 5: Download the MP3 and add it to your edit

    3 min

    An audio-only MP3 drops straight into any video editor or podcast app.

    1. At the top right of the track's cover image, click Download.
    2. Choose the audio-only MP3. The MP4 option is the track with its cover art as a video.
    3. Import the MP3 into your editor and place it under your footage.
    4. Lower its volume until speech is easy to hear over it.

    You should see the music on your timeline, playing under your video and voice.

    The track is shorter than your video?

    Make a full-length track with the Pro model. Or loop the main section in your editor and fade out at the end.

    Every track carries a SynthID watermark you can't hear. It marks the music as made by Google's AI.

You get

An original, instrumental music track that fits your video, saved as an MP3
