Melodic structure defines repetitions of the melodic figures in the period.
Sm = m1 ... mi ... m8
Where mi (i is the number of every bar) defines the same melodic figure accurate within sequence (sequence - repetition of the previous bar notes with its pitches shifted).

There are six variants for Sr in program:
Sm1 = 1 1 1 1 2 2 3 3
Sm2 = 1 2 1 2 3 3 3 4
Sm3 = 1 2 3 4 1 2 3 4
Sm4 = 1 1 2 2 3 3 1 1
Sm5 = 1 2 3 4 3 5 1 2
Sm6 = 1 2 3 4 5 5 3 3

Melodic line creation process is similar to "test" rhythm generation. The number of bars with different melodic figure depends on the Smj structure.
Repetition of the melodic figures doesn't mean their identity either. The variation of the other generation parameters, sequence effect and difference between repetition part of melodic figure and the whole melodic line finally give different sound.
