Turn Your Lyrics into a Song with AI: 30 to 120 Seconds, with Vocals

Write lyrics that are easy to set to music

When you turn lyrics into a song, the biggest factor is whether it's clear which part is the chorus. In BunCho (pronounced "boon-cho" — Japanese for "Java sparrow"), you write section tags in square brackets above your lines, and the song is built along those sections. Japanese pop calls the parts A-melo (verse), B-melo (pre-chorus) and sabi (chorus), which is what the screenshot shows. Without tags, the big moment may not land where you expect.

The other factor is the number of sounds per line. Japanese songs usually put one sound unit (a mora) on each note; in English, think in syllables and stress. When lines in the same section have similar counts, the melody settles and the song is easier to sing.

• Open the chorus with a short repeated phrase (for example: "Carry on, carry on, the story goes on")
• Verse sets the scene, pre-chorus builds the feeling, chorus says it outright
• Put the song title or your story's key word at the top of the chorus so it sticks
• Don't cram a line. It turns into rapid-fire singing that's hard to follow

Choosing genre, voice and length

The song maker asks you to choose the following. If you're unsure, pick a genre and leave the rest at the defaults.

• Genre: 8 options — anime opening, J-rock, idol pop, EDM pop, hyperpop, city pop, ballad and lo-fi
• Voice: female, male, duet or instrumental (no vocals)
• Length: 30 to 120 seconds. About 30 seconds of chorus suits social shorts; around 90 seconds works well for a music video
• BPM: leave it blank for the genre's default tempo. Add mood with short English words such as heroic or bittersweet

How to make a song from your lyrics

The song maker lives in the music video tab of the video editor. The song you make becomes the track for your music video.

1. 1Open the song maker in the music video tab

   Open your project's video and choose to make a song in the music video tab. If you already have a song you made yourself, import it with the upload option instead.

2. 2Set title, genre, voice and length

   Enter a title and choose genre, voice and length. You can also set the lyric language, BPM and mood here.

3. 3Enter your lyrics

   Paste your lyrics with a section tag above each part. No lyrics yet? Draft them from a lyric template or from your own story. You can also add a lyricist credit; if left blank, a generic author credit is used.

4. 4Get an estimate, then make the song

   Check the credit estimate, then make the song. It takes about 1 to 3 minutes. If you like it, choose to use this song, and tempo, chorus position and lyric timing are set up automatically.

5. 5Make a video to match the song

   From the same screen, go on to a music video where your character dances, an anime-opening-style video or a lyric video.

   

Songs are made on BunCho's own GPUs

The song maker runs on BunCho's own GPUs (ACE-Step 1.5). On the higher plans, songs made this way cost 0 credits up to a guideline limit of 30 songs a day and 300 a month. On other plans and during the trial, you see an estimate first and credits are used only when you agree.

When the GPUs are busy, you may wait in a queue. Reaching the limit never switches you automatically to a paid model.

Start from a lyric template

Writing to a template gives your song a tidier structure than starting from a blank page. The lyric templates come in 16 types, each with a set number of bars and what to write in each part.

• 

  Anime opening (TV size)

  About 88 seconds. Intro, everyday scene in the verse, tension in the pre-chorus, then a chorus that bursts open. A driving, up-tempo template.

  Use this template

• 

  Character song

  About 90 seconds sung in the character's own voice and catchphrases. A signature line in the chorus, and one spoken line in between.

  Use this template

• 

  Vocaloid-style song

  The word density and song structure typical of Vocaloid music (songs made with singing-synthesizer software).

  Use this template

• 

  15-second ad jingle

  8 bars, 15 seconds. Built so the shop or product name sticks in the last 3 bars.

  Use this template

Using your song, and the rules

You can use songs made in the Studio in your own videos and projects. BunCho's terms of use say music made in the Studio may be used for personal or commercial purposes, excluding material you brought in and anything involving third-party rights.

If you plan to release on a music distribution service, check that service's current terms, including how it treats AI-made music. Remixes are limited to your own songs or songs you have permission to remix.
