+This program will iterate over natural numbers, playing chords
+based on which prime divides given number. This results in
+following execution:
+
+step: 2 3 4 5 6 7 8 9 10
+      1   1   1   1    1
+        2     2     2
+	          3          3
+
+where each index corresponds to specific note from scale.
+Assuming scale [c;d;e] example above would be
+
+step: 2 3 4 5 6 7 8 9 10
+      c   c   c   c    c
+        d     d     d
+	          e          e
+
+which would resolve into:
+
+play c d c e (c & d) c d (c & e)
