                                                                         Melody

            The principles of a melody had started to develop for human voice. In the ages which is polyphony starts, music develop in churchs choirs. The harmony developed for the developing melody. Structure of a melody is that a melody has not contain big leaps and repetitions as much as possible. Ryhthm is simple. Shape of the melody must be simple for clarity. Notes of melody must belongs to chords. A melody frequently use closest steps in the key.

Choral Writing

            For the four part harmonization, the coral writing is important for observing parts of the chords clearly. It's develop for the choirs of churches in the past, then harmony developed accordingly. Coral writing consist of the four part such as bass, tenor, alto and sophrano.

            In the figure, when writing position of the chord is important. The object of the choral staves
writing parts without crossing. Thus parts can tracking eaisly in closest positions. Closest and wide positions can provide equilibrium.
            Parts can not crossing each other. For example, tenor part cannot be above of the alto part. Parts can not be an octave over above or below from the part which is closest. (Except bass)


Movement Rules
           
            There are some disonant movements which is thoght by the composers. Parallel perfect fifth and parallel octave doesn't acceptable movement. The parallel intervals can't move paralelly.



                                                                                                                                             Ex.18
           
            Consecutive perfect fifths are one of the disonant movements. The same parallels can't move up or down.



                                                                                                                                             Ex.19

            Other disonant moves is about the leaps on sophrano part. Direct octaves or perfect fifths can occured in this condition. Bass and spohrano part can't move to a perfect fifth or an octave.
