=> ((a b c d e f) (cdef) (d e f) (-bab fg) (b c d e f)
(cde) (-c -b a b c d e f) (abcde) (b c d e f))
In the example above a sequence of symbol melodies has the <start> points '(3 4 5) and the <count> values '(2 3 4) to be subtracted from these point. In the example below the type parameter 'c clusters or 'd divide the symbols in these patterns and subtracts (2 3 4) symbols from the <sections> '(1 3 5 7 9) from <start> points (2 3 4).
