English: Two digital drawings of how an imaginary keyboard would look like with 19-tone equal temperament. The top drawing divides the intervals in between the black sharp keys and the next white key up with smaller grey keys that play the flats of the next white key. Also, there are grey keys between E and F, and between B and C. The bottom drawing takes the space where the black keys would go on the keyboard and puts two keys in its place: a red key that is the sharp of the white key before it, and a blue key that is the flat of the white key after it. As in the top drawing, there are also grey keys (neither red nor blue) between E and F, and between B and C. The note names for the first octaves are given in the bottom of each drawing.
