Where two notes differing slightly in pitch form beats, the number of beats in a second is equal to the difference of the frequencies. If, then, the frequencies of the notes sounded differ by one vibration per second nearly, there will be one beat per...

...pipes of similar construction and identical pitch side by side on the same wind chest. The vibratipns **of the two pipes adjust themselves to complete opposition,...indicate that the higher note gains only two vibrations a** m1nute on the lower. Or it might be desired merely to ascertain the difference of the frequencies of... | |
