Song Writing
The circle of fifths, but it talks back.
Most theory tools show you a diagram. SAH's song writer is interactive: tap a key, hear its chords, build a progression, and get told why it works — in plain language, as you go.
Tap a key on the circle, then build a progression from its chords.
A songwriter's co-pilot
- Chords in every key — tap the circle to change keys and hear the diatonic chords instantly.
- Mood-based suggestions — pick a feeling and get progressions known to create it, each with a one-line explanation.
- Borrowed chords & secondary dominants surfaced when they'd add color.
- Cadences named as you build, so you learn the grammar while you write.
- Voice-leading hints nudge you toward smoother movement between chords.
