As can be seen, all steps are 77 cents wide except for two much narrower (22.5 cent) steps. Baseball[17] is thus a 15L+2s scale. In this scale there are two different approximations of 6:5 (at 331.5 and 308 cents), and two of 5:4 (at 407.5 and 385 cents). The sharper of the two major thirds can also double as a 14:11, and the sharper minor third can also function as 11:9, depending on the context. The interval of 253.5 cents can function either as a flat 7:6 (for example, in the triad 6:7:8) or else as a 15:13. | As can be seen, all steps are 77 cents wide except for two much narrower (22.5 cent) steps.
