As we know, interval spacing actually gets narrower in the next higher octave of an overtone scale. For a more natural appearance of adjacent octaves, we can shift the two corresponding frames (e.g. orange and blue) vertically by one octave. This even leaves room for the more dense intervals of the 6th octave in the upper right corner. | As we know, interval spacing actually gets narrower in the next higher octave of an overtone scale.
