A piano reference: chords, scales, theory. Full MIDI.

Virtual Piano

Play a full piano right in your browser, no MIDI keyboard needed and nothing grading you, just play. Tap the keys or use your computer keyboard, and every note sounds through a real sampled grand. Hold two notes and it names the interval; hold three or more and it names the chord, then links you to the theory behind it.

This is a just-play keyboard: it sounds great and names what you play, but it won’t score you. Want feedback on how you play? The Practice Room listens to a MIDI keyboard and coaches you like a teacher.
