Chord dissonance rises as harmonic number increases and interval shrinks

Evidence

The dissonance of the chord in each case is related to the entries in the final column, which indicate increased dissonance in the order C, c, d and D; it can be seen that the dissonance increases as the harmonic number increases and the musical interval decreases. — David M.
