Determining the beats per minute (BPM) of a song is crucial for various musical applications, including mixing, synchronization, and genre classification. BPM is the measure of how fast the beat of a song is, and it is expressed in beats per minute. There are several methods to calculate the BPM of a song. One common method is to use a metronome or online BPM calculator, which can provide an accurate measurement.
Manually counting the beats per minute is another method. Start by listening to the song and identifying the main beat, which is usually the kick drum or snare drum. Count the number of beats in a 15-second interval. Multiply this number by four to get the BPM. For instance, if you count 20 beats in 15 seconds, the BPM is 20 * 4 = 80.
