A metronome is a device that generates a regular sound to indicate beats. Each time the pendulum swung all the way to one side it caused a loud, mechanical click. The tempo is set either by turning a dial or, more commonly, by entering digitally the desired number of beats per minute, and the sound generated is a short, electronic ping.
Many newer metronomes offer additional features.
While not necessary for typical instrumental practice, these features can at times be useful. Types of Metronomes Metronomes come in a variety of shapes and styles. Larger metronomes are the size of a paper-back book or larger. Each style has its advantages and disadvantages. Larger metronomes usually have a louder click and, often times, make a more percussive sound than the smaller models.
