Proposal – the largest part of the period, ending with a cadenza. Usually P. exists only as a part of the whole. In some cases, it is still able to stand apart and acquire independence. meaning. This primarily applies to the open main part of the sonata form. It is often presented in the form of the initial P. period, the second P. to-rogo develops into a connecting party and leads to a side party. As a result, only the first piano of the period is designed as a thematically and structurally integral construction, and it is the form of the main part (L. Beethoven, 1st sonata for piano, part 1).
In a simple three-part form, I. can perform the function of a period as a form of its parts. In these cases, in the structure a1 b a2, section a is not a period, as usual, but P. (A. N. Skryabin, Prelude op. 7 No 1 for one left hand).
Difference between P. and the continuous period is connected by hl. arr. with type will conclude. cadence – in the period it is full, in P. – half. Plays a role and the degree of development of thematic. material, the completeness of its presentation; completeness, at least relative, implies a period, and obvious incompleteness – P. There is a different point of view, coming from the classical. German music-theoretical. school (X. Riemann). According to this concept, any one-part construction without a cadenza inside it, regardless of the type of the cadenza that completes it, is a P. (Satz); a period that is not divisible by P., in this case is interpreted as P.
