FIGURE 1

Frequencies along the Bohlen-Pierce scale compared to the Western scale. One cycle of each scale is shown in the figure. The starting point of the two scales is the same (220 Hz) and both scales are equal-tempered, thus making them analogs of each other except for the intrinsic differences in base and recurrence (2n/12 vs. 3n/13). The horizontal dotted and dashed lines represent major third and perfect fifth intervals in the Western scale and approximate 3:5 and 3:7 intervals in the Bohlen-Pierce scale.
