Key Passage was built by a pianist who wanted a better way to track the musical journey — not just a timer, but a living record of every piece learned, every session practiced, and every composer explored.
The classical piano world is rich with knowledge — composer histories, musical forms, interpretive traditions — but that knowledge lives in scattered places. Key Passage brings it together in one app, connected to the pieces you're actually learning.
For teachers, the gap between lessons has always been a black box. Key Passage makes practice visible without turning it into surveillance. Teachers see progress; students own their experience.
