I wrote a Ruby Library to help me compose my music album
summary
A Ruby library called Coltrane gem models notes, intervals, pitch classes, scales and chords and ships on Rubygems; tests use focused TDD and web crosschecks. It exposes a REPL and terminal renderer that prints piano, guitar and chord views, performs reverse progression search, finds pivot chords between keys (used to modulate), and outputs progressions you can play; roadmap includes a Rails + Opal progressive web app, image/JPEG renderers and migrating CLI from mercenary to Shopify Klee.
