[0002] A metronome is an instrument that uses the isochronism of a pendulum to control the sound of beats to measure time. The principle is that by changing the position of the pendulum on the pendulum arm, the number of beats per minute of the pendulum's vibration can be adjusted, thereby controlling the vibration period. It is usually powered by a spring, and the pendulum arm swings left and right to make a uniform sound. The pendulum block slides up and down according to the numbers on the scale to change the speed of the pendulum's swing. The lower part of the metronome is also equipped with a bell and an adjustment rod, which can make the bell ring every few beats, making it easier to tell time and time. When using a metronome, you need to first wind up the spring, adjust the number of beats per minute and the frequency of the bell, then place the metronome horizontally, and gently push the pendulum arm to start timing.
