As we can see, Stern-Brocot tree actually covers ratios greater than 1, but for met-MOS purposes, we only need to consider the left half of it (in fact, we only need to consider the left quarter of it, since generators greater than | As we can see, Stern-Brocot tree actually covers ratios greater than 1, but for met-MOS purposes, we only need to consider the left half of it (in fact, we only need to consider the left quarter of it, since generators greater than <span><math>\frac 12</math></span> are complements of those less than <span><math>\frac 12</math></span> and generate the same scales; but more on that later). | ||
So to quickly find a unique metallic generator, we only have to choose a ratio from the tree, and then choose either one of its two parent ratios; the line connecting these two ratios will be our interval. | So to quickly find a unique metallic generator, we only have to choose a ratio from the tree, and then choose either one of its two parent ratios; the line connecting these two ratios will be our interval. | ||
