Mechanical metronomes are the most basic, traditional metronomes. They came into prominent use during the 19th century. While there are a variety of manufactures and styles of mechanical metronomes, most mechanical metronomes operate by windup methods. While mechanical metronomes work like clocks, mechanical metronomes have an adjustable weight on the rod, which swings back and forth like a pendulum. This allows variable time counts and adjustable beats-per-minute.
Metronome software is available as freeware and shareware for Linux, Macintosh, and Windows operating systems. The types of software range from basic to advanced metronomes. Depending upon the application, its features can include: a track-setting memory function for time saving; special effects, such as fuzz and distortion settings; and variable beat and musical styles.
