Music performance very seldom conform to strict metronomic time. In the MIDI world the concept of humanization was introduced to change rigid computerized music tempo to be less machinelike. This is usually done by randomly changing different time aspects of the song.

Humanization is indicated as a percentage variation in terms of the base tempo. If the base tempo is 120BMP a variation of 10% will increase the tempo to 132BPM or decrease it to 108BMP. This is declared with the random attribute, used for random variation.
