As aresult, a piano sound will be heard every time when the nucleus of a loop
is traversed. The outer loops will be audible in a lower pitch and the inner ones ina
higher pitch. Additionally, by applying different length delays in the case of the loops
situated on different levels, the result will be that the outer loops will have smaller
frequency sound sequences than the inner ones. For instance, the above-presented
loop skeleton will be audible as it follows (do, fa, and si sounds have been built
into the I., II. and III. level loops; the ‘_’ characters represent the lengths of pauses):
do fa fa fa fa fa fa fado fa fa fa fa fa fa fado do do do do
When the algorithm has loops in both branches of a selection, we have “parallel
loops” at the same level. So, depending on the condition, we will hear them by turns.
