-## Euclidian
-
-Using round brackets, we can create rhythmical sub-divisions based on three parameters: beats, segments and offset. 
-The first parameter controls how may beats will be played. 
-The second parameter controls the total amount of segments the beats will be distributed over. 
-The third (optional) parameter controls the starting position for distributing the beats.
-One popular Euclidian rhythm (going by various names, such as "Pop Clave") is "(3,8,1)" or simply "(3,8)", 
-resulting in a rhythmical structure of "x ~ ~ x ~ ~ x ~" (3 beats over 8 segments, starting on position 1).
