Read about methods of motive development here.


 Figure 1.

On the interface level each method has its own tab (see Figure 1). The table below describes each item on the Figure 1.

Sequence Up. The original Motive notes are moved up.
Sequence down. The original Motive notes are moved down.
New Rhythm. The method composes a new rhythm for the Motives.
Repeat. The first motive is just a repetition of the original Motive. The second Motive on the panel is the original Motive transposed one octave up. The third Motive is the original Motive transposed one octave down.
Extraction. Three Motives, developed by notes extraction out of the original Motive.
Turn Over. The rhythm and the intonation content of the first Motive are turned. Only the intonation content is turned in the second Motive. The rhythm of the third Motive is turned.
Slightly vary rhythm. The method slightly varies the rhythm of the initial Motive.
Slightly vary pitch. The method slightly varies the intonation content of the initial Motive.
Arpeggio. This method changes the non-chord tones of the Motive on the chord tones.
Variation. The variation of the initial Motive.
Inversion. All intervals of the first Motive are inverted. Each second interval of the second Motive is inverted. For the third Motive, the algorithm chooses intervals randomly. After that the program inverts these intervals.
Ascending line. The program uses various methods of motive development to create one thousand Motives. Then the program chooses only the Motives, which have the form of an ascending line. Also, the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Descending line. The program uses various methods of motive development to create one thousand Motives. Then the program chooses only the Motives, which have the form of a descending line. Also, the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Ascending wave. The program uses various methods of motive development to create one thousand Motives. After that the program chooses only the Motives, which have the form of an ascending wave. Also, the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Descending wave. The program uses various methods of motive development to create one thousand Motives. Then the program chooses only the Motives, which have the form of a descending wave. Also, the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Caesura. The method emphasizes the end of the Motive by a pause or large duration. Read the more detailed description of the caesura term here.
Unify rhythm. The method changes all the durations of the first Motive to a sixteenth duration. An eighth duration is used for second Motive and a quarter duration is used for the third Motive.
Increase rhythm. The method adds a sixteenth duration to the all durations of the first Motive. An eighth duration is used for second Motive and a pointed eighth duration is used for the third Motive.
Shift rhythm. For the first Motive, the method shifts the time of the all notes by a sixteenth duration. The eighth duration is used for second Motive and the pointed eighth duration is used for third Motive.
Sequence and new rhythm. The program composes a new rhythm for the intonation content of the initial Motive. Then the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Sequence and inversion. Firstly, the method inverts the initial Motive (see method 'Inversion'). Then the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Sequence and variation. Firstly, the method varies the initial Motive. After that, the program moves the notes of the each Motive to smooth the transition from the previous Motive to the new Motive.
Continue. The program moves the notes of the initial Motive to smooth the transition from the previous Motive to the new Motive.
Two methods. Two randomly-chosen methods of the Motive development are used to create new Motives.

 Figure 2.

If you press one of the buttons, which are marked by number on Figure 2, the panel in the middle part of the main window appears. This panel contains the three Motives (see number on Figure 2). There is a button under the each Motive (see number on Figure 2). If you press this button then the program plays the corresponding Motive. Some panels have an additional button (see number on Figure 2). If you press this button then the program generates the three new Motives. If you press the button signed by number on Figure 2 then the program plays the all three Motives.
