Tempo or speed of music
Section outline
-
Tempo is a musical term that determines how rare or dense the pulse is in a song. We also talk about the speed of the piece.
The tempo can be expressed as a number. For example, tempo 120 means 120 pulses / beats per minute. This can be marked as 120 BPM (beats per minute).
The pulse of the human heart is about 60-80 BPM. In music we experience such a tempo quite calm. In the music and especially in the musical notes, the metronome mark MM = 60 is also used. This means the same as BPM, or beats per minute.
