How to Turn Your Lyrics into a Song with AI: A Step-by-Step Guide
From a poem or a toast to a finished, sung track: how to lay out your lyrics, describe the sound, choose between two versions and fix the lines AI singers get wrong.
By the NeonSong team · Published
You have words: a poem, a toast for a wedding, a chorus you've been humming for weeks. An AI music model can sing them as a finished track with vocals, drums and an arrangement in about a minute. Whether the result sounds like your song depends mostly on two things you control: how the lyrics are laid out, and how clearly you describe the sound.
This guide walks through both, then shows how to pick between versions and fix the usual problems. The examples use NeonSong, which generates songs with Google's Lyria 3.5 model, but the advice on lyrics and descriptions works with any lyrics-to-song tool.
1. Lay the lyrics out like a song
A model sings what it's given, line by line. Lyrics written as one long paragraph tend to come back rushed or with lines run together. Before you paste anything:
- Mark the sections. Put
[Verse],[Chorus]and[Bridge]on their own lines above each part. It tells the model where the energy should rise and which part to repeat. - Keep lines short and similar in length. A line you can sing in one breath is a good line. If one line is twice as long as its neighbours, split it.
- Repeat the chorus in full. Write it out each time it comes back instead of writing "repeat chorus".
- Don't overfill. Two verses, a chorus that comes back two or three times and an optional bridge are plenty for a song of about three minutes, which is roughly the longest Lyria makes in one go.
Here is the shape that works well:
[Verse]
Streetlights on the river, you were singing out of tune
Every word a little crooked, every word was true
[Chorus]
Sing it back to me, sing it back slow
All the little things I wanted you to know
[Verse]
...
2. Describe the sound, not the artist
The description is where most first attempts go wrong. "A nice pop song" gives the model almost nothing to work with. Say what you'd say to a session band:
| Part | Vague | Concrete |
|---|---|---|
| Genre | pop | warm 80s synth-pop |
| Mood | happy | hopeful, a little nostalgic |
| Tempo | upbeat | around 110 bpm, steady four-on-the-floor |
| Voice | singer | soft female vocal, close to the mic |
| Instruments | music | analog synths, gated drums, a bright bass line |
Leave out the names of real artists, bands and songs. Lyria refuses descriptions that name them, so "sounds like a famous band" becomes a failed request instead of a song. Describe what you like about that artist instead: the era, the groove, the instruments, the kind of voice. (NeonSong rewrites a refused description without the names and tries once more, but it's quicker to start without them.)
Not sure what to write? NeonSong's guided start asks about the occasion (a birthday, an anniversary, a song for yourself) and builds the description from your answers. You can edit it before generating.
3. Check the pronunciation (Chinese and Japanese)
If your lyrics are in Mandarin or Japanese, some characters have more than one reading, and AI singers often pick the wrong one: 长大 sung as cháng dà instead of zhǎng dà, or 生 read as sei where you meant nama. NeonSong's Reading Check flags those lines before you spend anything and suggests a spelling the model sings correctly, while your song page keeps the lyrics exactly as you wrote them. Why this happens and how the fix works.
4. Generate two versions and listen for three things
Each round in NeonSong makes two full versions from the same lyrics and description. They differ in melody, phrasing and arrangement, so you get a real choice. When you compare them, listen for:
- Every word is there. AI vocals occasionally slur or skip a word. Follow along with the lyrics.
- The chorus lands. It should feel like the moment the song was building to.
- The feel matches the occasion. A wedding toast sung as a dirge is a description problem, not a lyrics problem: go back to step 2.
If neither version is right, ask for another round, or change one thing in the description (the tempo, the voice, the genre) and try again. Changing one thing at a time makes it clear what helped.
5. Finish and use the song
Once you have a keeper:
- Master it to streaming loudness (-14 LUFS) if it's going to a platform or a video.
- Split the stems into vocals and instrumental if you want a karaoke version or to remix it.
- Time the lyrics line by line for captions and lyric videos.
- Download it. Everything you make plays free as a preview. After a top-up of any size, every song you make downloads as MP3 and WAV for personal use, with no monthly cap.
- License it for release. Putting a song on streaming services, or using it in monetized videos, ads or client work, needs a commercial license for that version.
Quick fixes
| Problem | Likely cause | Fix |
|---|---|---|
| A word is skipped or slurred | Line too long or crowded | Shorten or split the line; try the other version |
| A Chinese or Japanese word sounds wrong | Character with several readings | Run Reading Check, or swap in a homophone or kana |
| The request was refused | The description names a real artist or song | Describe the style instead of naming it |
| Right words, wrong mood | Description too vague | Add tempo, voice and instruments |
| The song ends too early | Too few lines, or too many for one take | Add a verse, or cut to two verses and a chorus |
