Figure 3
Comparison of the degree of chromaticism between the sight-reading materials and different styles of Western music. The small vertical arrows below the horizontal dashed line indicate the entropy value of each composer based on the references. For the references, we used the entropy values of a Gregorian chant, Mendelssohn and Schumann from Youngblood22, and Mozart, Hasse, and R. Strauss from Knopoff and Hutchinson21. The two vertical arrows above the dashed line indicate the entropy values of the sight-reading materials used in the present experiment.
