Question

How did Galileo use his knowledge in music to understanding the movement of a pendulum?

Answer 2

Galileo was taught Aristotelian physics at the university of Pisa. Galileo's discovery was that the period of swing of a pendulum is independent of its amplitude--the arc of the swing--the isochronism of the pendulum. Now this discovery had important implications for the measurement of time intervals.
