Song Cage is the songwriting tool for everything that happens before you hit record. Start anywhere — a chord progression, a melody, a line of lyrics — and the rest follows. Experiment freely, learn music theory as you go, and get the song idea down before it fades.

The problem every songwriter knows

You're using three tools to do one job — and losing ideas in the gaps

Your DAW or notation app

You figure out the chords

Built for recording or scoring — not songwriting. No lyric tools, no chord theory suggestions, no way to understand why a progression works or where it could go next.

Your notes app or voice memo

You capture the idea

The words land in one place, the melody in another, the chords somewhere else. You come back two days later and the magic is gone — because nothing was connected.

A browser tab

You search for the right word

Switching apps mid-session kills flow. By the time you find the rhyme and get back, you've lost the thread of where the song was going.

Song Cage is the songwriting tool that replaces all three — a chord palette with guitar and piano voicings, a lyric workspace with built-in rhyme finder, and music theory that connects them — on a single DAW-style canvas built to capture song ideas fast.

How it works

Capture your song idea. Then give it everything.

Song Cage has two moves — capture the idea before it fades, then develop it with tools that understand your song.

Capture it

Start anywhere — a chord progression, a melody, a line of lyrics. No setup, no required order. Just get the idea into the canvas before it disappears.

Chords and melody, wired together

Start with chords and lock your melody to the progression — notes snap to chord tones as you write. Start with a melody and the chord palette reshapes around it, surfacing the chords that fit what you've already played. Change either one and the other responds.

Lyrics wired to rhythm and meaning

Write lyrics first and build the rhythm and melody around them — syllables sit on beat positions, each one carrying its own pitch. Or lay down chords and a melody first and write words that land exactly where they need to. Click any word for rhymes, slant rhymes, and synonyms grouped by syllable count.

Theory that shows you where to go

Every chord available in your key — diatonic, borrowed, secondary dominants — with extensions that improve voice leading. A modulation panel that maps pivot chord routes between any two keys. You don't need to know the theory to use it — and you'll learn it just by writing.

Features

Everything a songwriter needs.
Nothing they don't.

What songwriters are saying

★★★★★

“I used to keep Guitar Pro, a notes app, and RhymeZone open simultaneously. Song Cage replaced all three. The modulation panel alone saved my last EP — I had no idea how to get from Dm to F# until it just showed me the pivot chords.”

JR
Jake R.
Singer-songwriter, Austin TX
★★★★★

“The Word Tools are genuinely better than anything I've used. Slant rhymes grouped by syllable count means I'm never forcing a lyric to fit the rhythm — it just flows. This is the first songwriting tool that understands how lyrics actually work.”

SM
Sarah M.
Indie folk artist, Brooklyn
★★★★★

“As a guitarist who's terrible at notation, this is everything. I can see the actual chord shapes, drag the blocks around like a DAW, and the borrowed chord library showed me colour I didn't know I had access to. Subscribed in 20 minutes.”

FAQ

Frequently asked questions

How do I write chord progressions for beginners?

Song Cage makes it easy — even if you don't know music theory yet. Pick a key, and the app shows you every chord that fits. Start with the I, IV, and V chords, then experiment with borrowed chords to add color. You learn music theory naturally just by using it.

Is there an app to write songs with chords and lyrics together?

Yes — Song Cage is built exactly for this. Most songwriting tools separate chord work from lyric writing. Song Cage puts them on the same canvas so your chords and lyrics stay in sync as you create.

What’s the best app to capture song ideas fast?

Song Cage is built for exactly that moment — guitar in hand, idea in your head. Open the app, pick a key, and you’re writing in seconds. No setup, no learning curve. You can also record audio directly in-app so the melody doesn’t disappear.

Do I need to know music theory to use Song Cage?

Not at all. Song Cage is designed to be a learning tool as much as a creative one. Beginners discover music theory naturally through use — you don’t need to read music or memorize scales. The app gives you the right harmonic options for your key and lets you explore from there.
