Figure 10. Vicentino’s seven chromatic 8ves, formed by combining the species of chromatic 4th and 5th analogously to his interpretation of the diatonic genus. At the bottom is Karol Berger’s proposed amendment for the seventh 8ve species (see my note 38). The size of each scale step, in 31sts of an 8ve, is shown beneath the staff, and the authentic or plagal divider is indicated with a dotted line.
