A mechanical or electronic device that is used to keep a steady tempo is a metronome.

Here are the steps for using a metronome:

1. Set up your metronome on a stable surface where you can easily see and hear it.
2. Turn on the metronome and adjust the volume to a comfortable level.
3. Determine the desired tempo for your practice or performance. This is usually measured in beats per minute (BPM).
4. Use the controls on the metronome to set the tempo to the desired BPM.
5. Start practicing or performing your piece, using the metronome's clicks or beats as a guide for keeping a steady tempo.
6. Focus on syncing your playing or singing with the metronome's beats, ensuring that each note or beat lines up correctly.
7. If needed, adjust the tempo setting on the metronome to gradually increase or decrease the speed of your practice or performance.
8. Regularly practice with a metronome to improve your sense of timing, rhythm, and overall musicality.
