PianoGrid

PianoGrid is a free piano learning and practice reference that runs in the browser without an account. Learners can find named keys on a keyboard, look up chords and inversions, hear chord and scale notes, and use beginner guides and printable blank staff paper.

I built it for people who need a quick visual reference alongside lessons or independent practice. I would welcome feedback on whether the chord and scale pages are clear enough for a first-time learner, especially on a phone.
