AI Music Generator: Make Original Tracks from a Prompt

An AI music generator works best when you treat the prompt like a short music brief: describe the genre, mood, instruments, tempo, duration, and whether vocals should be allowed. In Pipe2.ai, Music Generator turns that brief into a single MP3 track you can download or pass into a video workflow.

Verified against the current public form and run behavior on 2026-09-01: Music Generator requires a prompt and duration, exposes a vocals control, uses Auto routing between Eleven Music v1 and Lyria 3 Pro, and returns MP3 audio. This guide describes only controls that are present in the current public pipeline form.

Generate a Track in Five Steps

1. Open Music Generator. Start from the Music Generator pipeline. Use Auto unless you have a clear reason to pin a specific music model.
2. Write the brief. Name the genre, instrumentation, tempo, energy, structure, and intended use. “Warm lo-fi beat with soft Rhodes piano, vinyl texture, relaxed 85 BPM study mood” gives the model more to work with than “chill music”.
3. Choose the duration. Pick a length from 10 to 300 seconds. The rendered track can land slightly short or long, so choose a little extra time when it has to cover a fixed video edit.
4. Set vocals. Leave vocals allowed for songs where the voice is part of the genre. Turn vocals off for narration beds, documentary underscore, study loops, or any track that should stay behind speech.
5. Generate and listen through. Check the whole MP3 for unexpected vocals, awkward transitions, or a lead part that competes with dialogue. Regenerate if the musical direction misses.

The input is deliberately small: a 5-500 character prompt, a duration in seconds, and the vocals setting. The output is one MP3 asset. There is no real-time preview, so the practical loop is generate, audition, adjust the brief, and run again when needed.

Write a Prompt Like a Music Brief

A useful prompt gives the model musical decisions instead of a mood label. Include the pieces a composer or music supervisor would expect:

• Genre and role: lo-fi hip-hop study loop, cinematic trailer cue, corporate explainer bed, ambient drone, podcast intro.
• Instruments and texture: Rhodes piano, plucked guitar, deep brass, soft strings, granular pads, dry drums, vinyl noise.
• Tempo and feel: a BPM, half-time or four-on-the-floor rhythm, restrained pulse, driving groove, slow build.
• Structure: steady loop, final-third lift, clean ending, no intro, no drop, or a clear chorus if vocals matter.
• Placement: background under narration, YouTube intro, product reveal, documentary underscore, social reel.

For example:

Reflective documentary underscore, instrumental only. Soft piano, warm cello, and a restrained pulse around 80 BPM. Keep the arrangement sparse, build gently in the final third, then resolve cleanly.

Avoid naming a copyrighted song or asking for a named artist clone. You will usually get a better and safer result by describing the musical traits: era, instrumentation, rhythm, mix density, energy, and emotional arc.

Choose Vocals and Routing Carefully

The current workflow can route Auto requests to Eleven Music v1 or Lyria 3 Pro. Eleven Music v1 is the better fit for beat-driven styles and vocal-defined genres such as pop, hip-hop, EDM, rock, R&B, country, or K-pop. Lyria 3 Pro is the better fit for ambient pads, cinematic underscores, drones, and evolving instrumental textures.

That matters for prompts. If you want a song with vocals, say what the vocal should do: lead hook, spoken phrase, sung chorus, harmonies, or a genre-specific vocal style. If you want background music under speech, make the control and prompt agree: turn vocals off and write “instrumental only” or “no vocals”.

For long instrumental requests, remember that Lyria is capped near three minutes in the workflow. A request beyond that range routes to Eleven Music v1 so the generated track can cover the duration exposed by the public form.

Plan Duration and Review the MP3

Music Generator accepts 10 to 300 seconds in the public form. For a 45-second ad, ask for something like 50 seconds so the edit has a little room. For a five-minute background bed, expect to audition the result more carefully because small structure problems become more obvious over a longer track.

Short clips need different prompting. A 10-15 second loop cannot hold a full intro, verse, chorus, and outro. Ask for a sustained loop, a single groove, or a clean sting instead of song structure. For longer tracks, describe how the energy should change over time.

Keep the original prompt, generated MP3, and final video as separate assets. That lets you regenerate the music, change the mood, or swap in a different track without rebuilding the rest of the project.

Put the Track into a Video

Generated music is usually part of a larger asset. A common Pipe2.ai workflow is Music Generator to Video Reel: create the MP3, then add it as the background music while narration stays in its own input. If you need narration first, make the spoken audio with Audio Generator, then assemble the voice and music in Video Reel.
