All Piano Keys

This one is a picture quiz: every one of its 17 questions shows an image of a piano keyboard with a single key marked, and you choose its name from four options like A, Bb, D, and F#. Recommended for beginners who are learning where each note sits on the keyboard. Why 17 questions instead of the 12 keys you might expect? Because the black keys have two names each, so the same black key can be a sharp in one question and a flat in another. That overlap is the part that catches new players off guard.
