A metronome is a device (mechanical, electronic, or an app) that makes steady, regular clicks or beeps to mark musical tempo in beats per minute (BPM).

What does “metronome” mean?

  • In music, a metronome is used to keep a steady beat while practicing or performing.
  • It produces sounds (and often visual movement, like a swinging arm or blinking light) at regular time intervals that you can set, for example 60, 90, or 120 BPM.
  • Musicians use it to:
    • Learn to play in time
    • Practice at different speeds
    • Match the tempo a composer intended, often written as a BPM marking in the score.

Where does the word come from?

  • The word “metronome” comes from Greek:
    • “metron” = measure
    • “nomos” = law / to regulate.
  • So, the basic idea is “a device that regulates measured time.”

A quick example

Imagine you set a metronome to 100 BPM.
It will click 100 times every minute, one click per beat, so you can line up your notes exactly with each click.

TL;DR:
“Metronome” means a time-keeping device that marks a precise, adjustable tempo (in BPM) with regular clicks or flashes, mainly used by musicians to practice steady rhythm.
