JazzTree is a visual listening guide to jazz history. Explore 39 genres, see how they descend from, react against, and revive one another, and find about 350 records selected to make those relationships audible. EXPLORE THE LINEAGE Follow jazz across time in three complementary views: a focused rail, historical spans, and a full influence map. Filter connections by harmony, rhythm, form, instrumentation, improvisation, timbre, repertoire, social context, and technology. BROWSE 39 GENRES Search and sort genre profiles with concise histories, musical traits, key figures, contested boundaries, and gateway, core, and deep-listening albums. FOLLOW CURATED PATHS Take three ordered listening routes. Each step explains why one record follows another, and your progress stays on your device.
