Piano Companion is a music theory reference app for songwriters, producers, teachers, and students. Look up any of 1,500+ chords or 10,000+ scales instantly, build progressions, and explore harmony on iOS, Android, and Mac.


Whether you're stuck on a progression, blanking on a scale name, or just exploring — Piano Companion gives you the answer in seconds. Press the keys you know, and it tells you what you're playing.
Search by name or tap the keys you know. Piano Companion identifies what you're playing — even from a MIDI keyboard.
The Chord Progression Builder suggests chords that fit your key. Experiment with patterns, listen back, and find what sounds right.
See notes on the grand staff, fingering for both hands, intervals, degrees, and compatible scales — all in context, not abstract textbook diagrams.
