A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
r/piano (about 1.3M members, directory rank #823) covers all things piano related. Other instruments, classical listening and active music-making process each have clearer homes when the thread is not piano.
Stay on piano for piano technique, repertoire and gear. Use Guitar for guitar information exchange, classicalmusic for classical listening and discussion, and WeAreTheMusicMakers for the active process of making music across instruments.
