Lineage
The jazz piano family tree
44 influence connections run between the pianists on this site. These eleven are the ones whose position in the line is the most useful thing we have to say — no transcriptions of their hands survive in the app, but the tree knows exactly where they sit.
Everything below is scoped to the app's own tree, which is a teaching map and not a complete history of the music. Where a pianist's influences include someone the app does not teach, they are named here without a link, because trimming them to the people we have pages for would quietly change what the app actually says.

The whole tree moves
This page is a slice of it. The app draws the full graph, generation by generation, and lets you walk it in either direction — which is the only way a lineage is actually useful, because the interesting question is never who influenced one pianist but what a whole line of them was solving.
