Toggle the slider to change the number of keys in an octave. Click the green flag every time you reset NUMBER OF KEYS for the best experience! Full-screen mode is highly recommended. - Leftmost is going to be C4, rightmost is going to be C5. - Use qwertyuiop[]\asdfghjkl;'enter to use the piano keys. - Lower left is what key on the keyboard did you click. Lower right is what key on the piano did you click. Since there are pitches between keys, those won't show. (For example, a note calculated to be between D and D♭) - Didn't put double sharp and double flat in lol. - The pitches are crappy but this method adds more pitches to it. Have fun playing the piano... when there are 25 keys! #music #music #music #music #music #music #music #music #music #music #music #music
