Drawing the diagram for transfer of melodies of 4, 8, and 12 bars

The center of diagram is correlated with the conditional lowest note (it is assumed that human ear can not distinguish notes with value below 20-25 Hertz). Therefore, the conditional inaudible octave is represented by the empty square in the center. The size of first working octave is calculated through the 1:2 proportion on the "note pitch" coordinate.



Proportion 1:2 corresponds to the correlation of the note frequencies in the octave. Compare, for example, "La" note of the different octaves: 220 Hertz, 440 Hz, 880 Hz. The same is true for other frequencies of notes when rising by the octave the note frequency has the doubled value (true for the even-tempered system).


Further, we divide the first working octave into twelve paths (corresponding to 12 semitones of octave).



Motion can be started from any diagonal. The motion can be counterclockwise or clockwise. (However, in all examples the beginning point will be the upper right diagonal, and the motion will be counterclockwise).


Since the melodies usually cover two octaves, we have to add on the outside the space for the higher octave by the same principle (preserving the proportions of external square to the first internal one).



Now the tonality of musical composition is to be determined in the diagram the note representing the tonality corresponds to paths 0 and 12. With "La" tonality, for example, path 2 will be intended for "Si" note, while with "Do" tonality path 2 will be intended for "Re" note..


When the notes are transferred to the appropriate paths with observance of "time" coordinate, the points are connected with the lines smoothed by the Bezie Curves principle.
