How has a metronome changed over time?

Metronomes have evolved significantly from their mechanical origins in the early 19th century, where they used a pendulum to produce a steady beat. The introduction of electronic metronomes in the late 20th century allowed for greater accuracy, volume control, and various time signatures. Modern metronomes often feature digital displays, customizable settings, and even integration with apps for enhanced functionality. Overall, these advances have made it easier for musicians to practice rhythm and tempo across different genres.
