Music and mathematics
Time, rhythm, and meter

Without the boundaries of rhythmic structure – a fundamental equal and regular arrangement of pulse repetition, accent, phrase and duration – music would not be possible. Modern musical use of terms like meter and measure also reflects the historical importance of music, along with astronomy, in the development of counting, arithmetic and the exact measurement of time and periodicity that is fundamental to physics.

The elements of musical form often build strict proportions or hypermetric structures (powers of the numbers 2 and 3).
