What is BPM (Beats Per Minute) ?
It’s used to describe the tempo of music.
A piece of music’s tempo is typically written at the start of the score, and in modern music is usually indicated in beats per minute (bpm). This means that a particular note value (for example, a quarter note, or crotchet) is specified as the beat, and that the amount of time between successive beats is a specified fraction of a minute.
it is widely used by DJ for creating playlist with similar tempo.
