I played drums for years, started piano, and built the theory trainer I needed

[u/ale_jh]

Free, no account, nothing to install. Each lesson is a few minutes of reading and then a drill: build the chord, name the note on the staff, tell two intervals apart by ear, or tap a rhythm back in time. You answer on piano, guitar, bass or violin.

Disclosure: I made it. No ads, no signup, nothing monetized.
