Large-scale thematic structures

In the theory of music , scale-thematic structures ( structures of musical speech, rhythm syntactic structures, syntactic structures ) are structures of a musical theme , which are formed from a combination of motifs and phrases of various lengths.

There are several types of scale-thematic structures:

• summation (1 + 1 + 2) - a construction in which periodicity is followed by a non-periodic construction, approximately equal in scale;
• progressive summation (1 + 1 + 2 + 2 + 4 + 4);
• crushing (2 + 2 + 1 + 1) - a structure in which a smaller periodicity follows a larger periodicity;
• progressive crushing (4 + 4 + 2 + 2 + 1 + 1);
• periodicity (2 + 2 + 2 + 2) - a construction consisting of two or more identical parts;
• crushing with closure (2 + 2 + 1 + 1 + 2) - crushing with subsequent summation.
