Nocturne In C Sharp Minor - Frideric Chopin

With a close arrangement of the triad and its appearances in the four voices, the voices (except for the bass) are separated by a third or a quarter, wide - by a fifth, sixth and an octave. Bass can form any interval with a tenor. There is also a mixed arrangement of A. , which combines signs of a close and wide arrangement. In A. , two sides are distinguished: the functional, determined by its relation to the tonic of the fret, and the phonic (colorful), depending on the interval composition, location, register, and also on the muses. context. DOS the regularity of the structure of A. remains to the present. time tertsovoe composition. Any deviation from it means the introduction of non-chord sounds. At the end of the 19th and 20th centuries. attempts were made to completely replace the Tertz principle with the quartz principle (A. N. Skryabin, A. Schoenberg), but the latter received only limited use.
