Song Cage is the songwriting tool for everything that happens before you hit record. Write in your browser, on Mac or Windows, or inside your DAW as an AU/VST3 plugin. Start anywhere: a chord progression, a melody, a line of lyrics. The rest follows. Experiment freely, learn music theory as you go, and get the song idea down before it fades. Over 2,000 users in under 6 months with almost no ad spend, and 700+ new signups in the last 30 days alone.
