Counting Notes on a Piano

If we count the notes on a piano, we get the picture below. Remember that we count as in the Land of Twelve. You can see that the same pattern of keys comes back several times. In the same way, the last digits repeat themselves. For instance, the white keys immediately to the left of the pairs of black keys, all have a number with the last digit equal to 0.
