The smartChord Song Analyzer is a world first. It automatically recognizes the chord progressions and the key of any song — so you can instantly see how your favorite tracks are built and get inspiration for your own music.

Instead of spending hours figuring out what’s going on harmonically, you feed the analyzer with a song and it hands you a clear map: every chord, the key, and each recurring progression ranked by how often it appears.

Why Use the Song Analyzer?

Four core benefits — whether you’re writing, learning, or just curious about a song:

• Get inspired. Study the chord progressions behind successful songs and reuse the patterns in your own writing.
• Understand songs faster. See every chord, the key, and every recurring progression automatically.
• Train your ear for keys. The analyzer shows the key of the song and of each progression, helping you learn to identify them yourself.
• Turn theory into practice. Create exercises straight from any detected progression and drill them in any key, tempo, or tuning.
