A musician-curated database — every chord type, scale, and mode across all 12 keys. Vetted fingerings, audio playback, and an interactive keyboard. No AI filler, just accurate reference data.
See notes highlighted on a real piano keyboard. Click keys to hear them. Toggle between inversions, fingerings, and accidental modes.
Hear every chord and scale played back instantly. Adjust BPM, direction, and play mode. Practice along with the built-in play-along feature.
Every fingering is sourced from the database and checked against 25+ years of teaching experience — not crowdsourced or generated.
