What is a metronome?
A metronome is a device that produces a steady pulse to help musicians play in time. The pulse is measured in BPM (beats-per-minute). A tempo marking of 60 BPM equals one beat per second, while 120 BPM equals two beats per second.
A metronome is commonly used as a practice tool to help maintain a steady tempo while learning difficult passages. It is also used in live performances and recording studios to ensure an accurate tempo throughout the performance or session.
Using the metronome
Start by selecting a tempo using the slider or, the left and right arrow keys on your keyboard. Alternately, you can tap the tempo by clicking the "Tap tempo" button at the desired tempo or by using the "t" key on your keyboard.
Select the number of beats per measure at the bottom. Most music has 4, 3 or 2 beats per measure, in music notation denoted by time signatures such as 4/4, 3/4, 2/4 and 2/2. You can always select 1 if you don't know the number of beats per measure.
