A repeater is a complication in a mechanical watch or clock that chimes the hours and often minutes at the press of a button. There are many types of repeater, from the simple ...
Vivaldi took great pains to relate his music to the texts of the poems, translating the poetic lines themselves directly into the music on the page. For example, in the middle section of "Spring", when the goatherd sleeps, his barking dog can be heard in the viola section. The music is elsewhere similarly evocative of other natural sounds.

Metronomes may also include synchronized visual motion, such as a swinging pendulum or a blinking light.
Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), the period—the interval between beats—is half a second ...
