The vibration ratios of the intervals between the successive notes were then calculated from the numbers thus obtained, and were found to be those given above. The Fifths which can be formed from these tones are:
If, from the vibration numbers above, the vibration ratio of each of these Fifths be calculated, it will be found that each of the following fiye intervals has the exact vibration ratio of 3 : 2 ; that is to say, the following are Perfect Fifths:
Thus, for examplej
