Beats Per Minute
Beats Per Minute Definition - What is Beats Per Minute?
Beats per minute, or BPM, is a term for measuring the tempo of a piece of music. "Tempo" is a musical term for the pace, or speed of a piece. Beats per minute is the unit of measurement for measuring tempo. A "beat" is the standard measurement for a length of a piece of music. Different pieces are written in different time signatures, and time signatures determine the value of a beat. For example, a time signature of 4/4 indicates that a quarter note (1/4) is one full beat, and that there are 4 beats in each measure of the song. A song written in 4/4 will have a different tempo when played in a different time signature, because the value of the beat and the number of beats per measure will change, and this difference in tempo is shown by a difference in the number of beats per minute in the song.
