title: Codex Taught Me How to Play Piano
description: >-
  Every CEO Dan Shipper plugged his piano into his computer and asked Codex to
  build him a simple app that shows what he’s playing. Suddenly, the notes,
  chords, and theory behind his favorite flourishes were visible in real time.
  In this video, Dan uses Codex to understand a passage from one of his favorite
  songs, break down why it works, and turn noodling around at the piano into
  actual learning. It does not replace a real teacher, but it does show
  something bigger: if you're curious, this is the best time in the world to
  learn anything. Every is the only subscription you need to stay at the edge of
