A first dance nobody else has danced to.
Couples used to pick a first-dance song from a list. An AI wedding song generator makes one from the actual story — how you met, the promise you are making, the names — as a complete, sung track you can play at the venue and keep forever. This guide covers the moments a custom song fits, how to brief it, and the practical side: length, instrumental versions and files for the DJ.
01Where a custom song fits in the day
- The first dance — the obvious one. A slow, timeless arrangement built on your story; three minutes is right.
- The entrance — an instrumental or a short upbeat song with your names in the hook as you walk in.
- Parent dances — a song from a daughter to her father or a son to his mother, with the specific memories in it.
- Vows to music — paste your vows as lyrics and hear them sung, as a gift for the morning after or the anniversary.
- The video — an original song for the highlight film, so the video never gets muted for a music claim.
One prompt with the story in it. The song comes back with the story in it.
02How to brief a wedding song
Give the engine four things: the names (with phonetic spellings if needed), the story in two or three concrete moments, the promise you want the chorus to make, and the sound — usually acoustic, piano, soft strings or a gentle soul groove, and the word “timeless” if you want it to age well. Avoid “epic”, “cinematic” and heavy drums for a first dance; those make songs you cannot slow-dance to.
Example: “slow acoustic first-dance song for Ana and Tom, warm male vocal, we met in a university library, she corrected my Spanish, the chorus promises to keep learning each other, gentle strings, timeless”.
03Prompts for each moment
- slow acoustic first-dance song for Ana and Tom, warm male vocal, met in a university library, she corrected my Spanish, chorus about learning each other for life, timeless
- instrumental wedding entrance, bright piano and strings, joyful, builds for 40 seconds into a big open chorus, no vocals
- father-daughter dance song, country ballad, female vocal, teaching me to drive in the church parking lot, the porch light he always left on
- mother-son dance, soft soul, male vocal, the Sunday kitchen radio, her hands on my shoulders, thank you without saying goodbye
- upbeat pop song for the wedding video of Leila and Sam, mixed vocals, Lisbon in June, the tram, everyone dancing on the rooftop
- our vows set to music, piano, female vocal, sung exactly as written, gentle, under three minutes
04Instrumental versions, length and the DJ file
Instrumental: ask for “instrumental” in the prompt or switch vocals off, and you get the arrangement without a singer — useful for the entrance, the signing and the dinner. Length: songs come out around two to three minutes; if you need the dance to run longer, use the extend tool from any second of the track. Files: download the MP3 from your library and send it to the DJ or the venue a week early with a note on where to start and fade; a share link works for the couple’s families.
Songs generated from your own prompt and lyrics are yours to use under the app’s terms, including in your wedding video on YouTube or social platforms, so the film keeps its sound.
05Writing the lyrics yourselves
Many couples write the chorus together and let Octa write the verses from the story. Paste the chorus under a [Chorus] tag and describe the verses in the prompt; the engine keeps your words exactly and fills the rest. If you paste the vows in full, keep each line under about ten syllables and split long sentences into two lines so they can be sung, not read. The lyrics guide has the details.
