How to Write a Song With AI: A Beginner's Guide

For most of music history, writing a song meant first learning an instrument, then learning theory, then spending years developing the craft of fitting words to melodies. This kept songwriting in a small club.

That club is now open. Not because AI replaces craft — it doesn't — but because AI handles the *technical* parts (chord choice, key, rhythm, production, even melody if you want) so a complete beginner can ship a real song using the part that was always the actual point: a feeling and an idea.

This is a step-by-step guide to writing your first one.

The five things every song needs

Every finished song has five components:

A feeling. What the song is about emotionally. This part is yours; AI can't supply it.

Lyrics. Words that carry the feeling. AI can draft these from a description; you edit until they feel like yours.

A melody. A vocal line. AI can generate this from your lyrics, or extract it from a hum you record.

Chords and arrangement. The harmonic and rhythmic backing. AI handles this entirely.

Production. Mixing, instruments, vocal performance. AI handles this entirely.

A beginner's job is to nail #1 and have a strong opinion about #2. The rest is delegated.

Step 1 — Find a feeling: pick a mood and a key

Songs are about emotional specificity, not generality. "Sad" is too vague to write a song around. "The specific kind of sad you feel walking past the apartment of someone who used to live with you" — that's a song.

Write one or two sentences in the Notes app describing the *exact* feeling. Add a season, a place, a time of day if you can.

Then pick a key that matches. Major keys feel hopeful, expansive. Minor keys feel pensive, dark. If you're not sure, use Listen Mode in Larka and play the first chord that comes to mind on any instrument — Larka tells you the key. Or just pick a minor key (most modern pop is minor anyway).

Step 2 — Get lyrics on the page

Open Larka's Notes tab. Paste your one-sentence feeling. Tap AI Refine with a steering prompt like "expand this into a song lyric — 8 lines, present tense, one concrete image per line."

What comes back is a draft. Read it aloud. Cross out lines that feel generic. Keep the lines that surprised you. Keep especially the lines that mention something *specific* — a name, a street, an object, a smell.

Now tap AI Continue if you want more verses, or use the Rhyme Helper if you're stuck on a line. Iterate until you have one verse and one chorus you're happy with.

Don't overthink it. The first version of a lyric is always worse than the third.

Step 3 — Find chords that fit your mood (no theory required)

If you don't play an instrument, skip ahead to step 4 — Larka's AI generation will pick chords for you based on the key and mood you've set.

If you do play, open the Chord Diagrams screen and try chords from your chosen key. Larka surfaces the diatonic chords (the ones that naturally belong in your key) at the top. Pick four. The classic pop progression I-V-vi-IV (in C: C-G-Am-F) is famous for a reason — it works.

Record yourself playing the progression. Larka analyzes your recording and confirms the key, BPM, and chord names. Now you have audible chords matching your lyric.

Step 4 — Generate your first version and listen critically

Back in your Note, set the genre, mood, and key. Tap Generate.

Thirty to ninety seconds later, you have a full song with AI vocals singing your lyrics over a generated arrangement.

Listen all the way through. Don't judge it on the first listen. Listen *twice*. The first listen is shock — it's strange to hear your words sung. The second listen is when you can actually evaluate.

Ask yourself: does this carry the feeling I wrote in step 1? Does the energy match the lyric? Does the vocal performance feel right?

Step 5 — Iterate: change one thing at a time

Almost no first generation lands perfectly. The fix is iteration, but iterate in single-variable steps so you learn what each control does:

• ·Wrong vibe? Change *only* the genre. Generate again.
• ·Right vibe but wrong energy? Change *only* the mood.
• ·Right vibe and energy but wrong vocal? Generate again with the same settings — vocal performance varies between takes.
• ·Lyric line that lands awkwardly? Edit just that line in the Note. Regenerate.

Three to five iterations is normal. Some songs land in two. Some take ten.

Step 6 — Finish it: title, cover art, share

Once you have a take you love, give the song a title (Larka can suggest one based on the lyric). Tap Generate Cover Art — pick a visual style that matches the mood. The artwork is generated from your actual lyrics, not a blank prompt, so it tends to fit.

Share the MP3. To friends, to Instagram, to TikTok, to anyone who'll listen. The first song you ship matters more than how technically polished it is. You wrote a song. You're a songwriter now.

Beginner mistakes to avoid

Trying to write a "good" song. Aim for a *finished* song. Quality comes from finishing many songs, not from agonizing over one.

Vague lyrics. "I feel sad" is not a lyric. "The kettle whistles in an empty kitchen" is. Specificity is everything.

Hating the AI vocal. AI vocals are uncanny on the first listen. Give it three songs before you decide it's not for you.

Skipping the feeling step. People write songs about *something*. If you don't know what your song is about, the AI can't either.

Comparing your first song to a hit single. Compare it to the song you would have written without these tools. That's the honest measure.
