A generating interval is required to generate the steps of a scale. In the case of a Pythagorean tuning, the generating interval is a 3:2 fifth. Notice that a sequence of five consecutive upper 3:2 fifths based on C4, and one lower 3:2 fifth, produces a seven-tone scale, as shown in Fig. 2. The Perfect Octave Creates Harmonia Working with his seven-stringed lyre, and thinking of the divisions of the strings that he had discovered, Pythagoras realized that for the relationships to be complete and balanced, the perfect interval of an octave (e.g., C1-C2) must be part of the existing scale. However, Pythagoras’s real goal was to explain the musical scale, not just intervals. To this end, he came up with a very simple process for generating the scale based on intervals, in fact, using just two intervals, the octave and the Perfect Fifth.
