Turn a Written Idea Into a Complete Song
Describe an idea, story, mood, or sound in your own words. Lacuna turns the brief into a complete song with AI lyrics, vocals, melody, and instrumentation.
How it works
From a Plain-Language Brief to a Playable Song
1Step 1
Write the outcome, not prompt syntax
Tell Lacuna what the song is about, how it should feel, where it will be used, and any sound you already hear. One sentence is enough; add tempo, era, or instruments when those constraints matter.
2Step 2
Choose what the words should do
Ask the Agent to develop original lyrics, add lyrics yourself, or keep the result instrumental. Your description guides the song without becoming the sung text, keeping production notes separate from the vocal.
3Step 3
Generate, listen, and keep shaping
Generate a take and listen for the melody, pacing, vocal character, and arrangement. Then open the canvas to compare versions, reinterpret the brief, or continue the track.
Prompt recipes
Four Kinds of Text That Make Strong Song Briefs
You do not need music terminology. Give the model the information you already know, combine subject and sound in the same brief, and leave the rest open. These patterns work for a song from a written idea or instrumental music from a prompt.
A story seed
For a subject with an emotional turn: “A warm indie-folk song about two childhood friends meeting again in the town they left, intimate female vocal, acoustic guitar and brushed drums, bittersweet but hopeful.”
A scene to score
For instrumental music around a picture: “A slow cinematic instrumental for sunrise over an empty city, felt piano and soft strings, no drums at first, gradually opening into a hopeful final minute, no vocals.”
A production brief
For a sound you already hear: “Glossy 1980s synth-pop with bright arpeggiators, tight electronic drums, restrained verses, a wide final chorus, and a clear male vocal.”
A hook premise
For an idea the Agent can develop: “Write and produce a playful pop song about being late to everything except falling in love, with short verses and one memorable repeated hook.”
Control when you want it
Start in Agent Mode. Switch to Custom at Any Time.
Keep a short brief conversational, or turn it into a detailed production specification when direction matters.
Agent mode for incomplete ideas
Describe what you know and let the music Agent shape it into a generation-ready plan. Use it when you have a story or feeling but no genre, structure, or lyrical angle yet.
Custom mode for direct control
Set the style, vocals or instrumental, vocal direction, lyrics, title, and model in one form. Agent drafts carry into Custom mode for field-by-field revision.
Three models for different jobs
Choose Aether for broad styles and advanced controls, Reverie when close lyric adherence matters, or Echo for a structured full-song take up to three minutes. They are different routes, not quality tiers.
Advanced steering when needed
With Aether, exclude unwanted styles and control how closely or experimentally the result interprets your brief. Narrow a familiar production target or leave room for an unexpected arrangement.
After generation
A Written Brief Does Not End at the First Render
Keep every result connected to the brief and its revisions, so the text-to-music process continues after the first take.
Compare directions, not filenames
Generations, edits, and stems stay connected on a visual canvas. Compare alternate interpretations, follow each branch to its origin, and keep the promising route intact.
Change the whole-song interpretation
Remix a finished take into another genre, mood, or production style. The same premise can become a quiet acoustic version, a club treatment, or another contrasting direction.
Continue or repair the arrangement
For supported tracks, extend from the waveform or replace one section while preserving the rest. Keep a strong opening or chorus and address only the part that needs work.
Take the mix apart
Split vocals, drums, bass, and instruments into stems for remixing, practice, voiceover, or DAW work.
Finish and inspect the track
Master the mix, follow synchronized lyrics, and inspect BPM, key, chords, spectrum, and loudness before choosing a final version.
What people make
Built for Ideas That Are Easier to Describe Than Compose
Turn ideas you can describe into music you can use.
02
Video, podcast, and game creators
Describe the scene, pace, emotional arc, and where the music should build or recede for an edit, spoken segment, trailer, or playable moment.
03
Songwriters at the idea stage
Explore themes, hooks, structures, and musical treatments before finalizing the lyric. A draft that turns words into a song can test the premise as folk, pop, rap, or another form.
04
Producers and creative directors
Turn production briefs into reference tracks, compare interpretations with collaborators, and export stems for arrangement studies, presentations, or further DAW production.

FAQ
Text-to-song questions
A text-to-song generator turns a written creative brief into music. Describe the subject, mood, genre, instruments, vocals, or intended use, and Lacuna creates a complete song or instrumental without music notation.
Not automatically. Your prompt describes the song, so production instructions do not need to be singable. Ask the Agent to write lyrics, paste your own in Custom mode, or use the existing-lyrics workflow for exact wording.
One clear sentence is enough. Add the subject, mood, genre, instruments, vocal character, or use only when it matters. Leaving choices open gives the model room to interpret.
Yes. Give the Agent a story, point of view, emotional turn, or hook premise to develop into original lyrics.
Yes. Choose Instrumental and describe the scene, energy, pacing, instruments, and intended use. A text-to-music generator interprets those details as production direction without adding a sung vocal.
Choose Aether for broad styles and advanced controls, Reverie for close lyric adherence, or Echo for a structured song up to three minutes. Check the selector for current language and capability details.
No. Length depends mainly on lyric amount and structure. Describe the arrangement and provide a complete lyrical structure for a fuller song.
Yes. Compare canvas versions, remix the full track, use supported extension or section editing, split stems, master, regenerate cover art, and share the selected result.
Yes. Sign-in includes complimentary monthly credits; audio downloads require a paid plan.
Pro and Ultra users can download a personalized commercial license agreement. Usage depends on that agreement and your rights to every input, so review it before publishing or monetizing.
