'Music is the pleasure the human mind experiences from counting without being aware that it is counting‘
Gottfried Leibniz
(17th Century Philosopher)Slide2
DJs like Calvin Harris need to use the mathematical part of their brains when they are mixing different tracks together.Different tracks will have a different number of beats per minute.
They will also have different rhythms within them.
DJs need to be able to work out how to best fit different tracks together so that the change between them goes smoothly.Slide3
