When the beat circle and progress at the same time it is a SPIRALLING ENCOMPASSING movement...
An increasing irrepressible beat and pulse growing which command time itself...
Life is this increasing pulse...
it is the reason why time obey music and music dont obey time but command it...
We can listen to it in one of the most powerful piece of music ever written OR like in the pygmies songs...Or like in the yoruba talking drums under this post...
Music is not sound but what is behind sound: Life asciension itself....
