The lineage map
One column per Sunday. Lanes are the five streams the course follows. Curves show which earlier modules each one builds on. Click a node to open the module. Hover to see its connections.
Sunday schedule
Every module has its Sunday. Push one back a week and everything after it shifts too. Pick any other day for a single module and later Sundays only move if they would collide.
Sound words
The vocabulary for describing what you hear, gathered from all 36 modules. The threads show how one idea about sound travels through the century. The word list is for drilling: define each word aloud and name a song where you heard it, then check.

Threads through time
Each row is one idea about sound; a filled cell means that Sunday's vocabulary uses it. The bars on top count the words that appear for the first time that Sunday. Hover a cell for the exact words, click it to open the module.
