Built for music theory learning
Piano Companion teaches music theory through hands-on practice. The app labels secondary dominants, leading tones, and common degrees — Tonic, Supertonic, Mediant, Subdominant, Dominant, Submediant, Leading tone (in major) and Subtonic (in natural minor) — so you can study how progressions are built. Listen to relative scales side by side, browse compatible chord-and-scale pairings, and try modes you've never used.
Songwriting and composition
Use the chord wheel and progression sequencer to compose songs from scratch. Add arpeggios, swap chords for relatives, and play the result on the built-in piano or through MIDI.
