Binary Form Explained

The binary form in music is a structure with two complementary sections that are contrasted or linked. These sections are the ones that open the room and the others that have closed it. The binary form is a musical form in 2 related sections, which are usually repeated. Binary is also a structure used to choreograph dance. In music, this is usually listed as A-A-B-B. In the rounded binary, the beginning of A in the home key returns somewhere in the middle of the second restart. It is not necessary for all the A`s to return (although this is often the case) – just the beginning. While the return material may be identical, it`s also common to see slight variations like octave changes, accompanying patterns, and/or melodic embellishments. If there are variations, you should always be able to feel the feeling of return when material A returns. If you`re not sure, you can expect the harmonic analysis to remain essentially the same, chord changes will likely be in the same metric places, and the degrees of scale of the melody will also be in the same order and at the same metric locations; Just be sure to consider the possibility of slight deviations in the areas listed above. Symmetric binary system is a term used to characterize a visible feature of the binary form that can be simple or rounded. We have a balanced binary form when the closure of the first section and that of the second section have related material arranged in the same way. “Balanced” is a term used to describe a binary shape (simple or rounded) in which the tail of the first repeat returns at the end of the second cover.

This return will be done in the home button of the room, even if it was in a different key during the first restart. In Example 7, (x) represents the music at the end of the first cover (section A) and its return at the end of the second cover. In the simple binary, there is no significant return on the opening material in the second recovery. Instead, in the second cover, the material takes one of two possible manifestations: the material comes from the first 8 bars that open the first section. The recapitulation with the material of the first section characterized the piece as a rounded binary. The simple binary form is all about the development of a single musical material into two essential parts. This practice is very popular and is often used in instrumental dance suites of the Baroque period. As the normal binary form is also the simple binary form of in two sections. Structurally, the binary form is always in two main sections with an AB pattern. As a result, sections A and B are different sections with different and closely related thematic materials.

The main difference between rounded binary shapes and small ternary shapes is the type of material between section A and the return of the thematic material from section A to the end of the shape. In the rounded binary form, this additional material is called an excursus and does not present itself on its own as a satisfactory musical section, while in the ternary, this material represents a complete musical section for itself (although it can finish the tonic if it is part of a continuous form). A type of binary form where the material returns to the beginning of Reprise 1 somewhere in the middle of Reprise 2. Both performances of this repeated music should be in the home button. As with other forms, the first resumption of a binary form can be described as harmoniously open or closed. The second cover can also be described this way, but since binary forms are supposed to be monotonous, it is usually implicit instead. Each part of the binary form usually ends with standard cadence types, especially in 18th century classical music. But the stylistic preferences of the 19th century changed the cadential expectations, especially for the first part: composers sometimes opted for lower graduation levels, which ended with progressions extending the tonics instead of standard cadence types (examples: Schumann, Papillon, 1 [m.

8] & 7 [m. 8], Children`s Scenes, No. 9 [m. 8]). A piece in binary form can be classified according to a number of characteristics: in detail, the binary form is a two-part musical form. It is characterized by two compatible and connected sections, which are roughly equivalent and form two different patterns. In the 18th century, half-cadences before the return of A in rounded binary form are quite common. In the 19th century, however, composers could also eliminate or obscure this boundary, as Chopin did between millimeters. 16 and 17 in the rounded binary form found at mm. 1–24 of his Polonaise in A major, Op. 40, No.

1. Nevertheless, we must be aware that contrasts are not well established in a simple binary approach. Most often, the original theme is used to establish all the material in both sections. For example, if section A is a period (using Caplan naming conventions; referred to elsewhere as a parallel point), the first sentence (“previous”) of section A begins with a basic idea (usually for half of the sentence) and ends with a relatively low cadence, and the second sentence (“consistent”) begins with the same basic idea and ends with a stronger cadence; If section A is a sentence, the first half of the section consists of two repetitions of the basic idea (the second can be transposed or slightly modified), and the rest of the sentence will lead to a cadence. In a rounded binary form, at the end of section B, if section A was a sentence, the beginning of the sentence usually returns, possibly shortened, followed by the cadence; If a period is, the same is true, but since the precursor and consequence of a point both begin in the same way, it is usually easier to say that the entire coherent sentence returns. In both cases, however, it is the basic idea that comes back, followed by the cadence. In a balanced binary system, the basic idea does not have to come back. There is room for discussion about how much material needs to return before the pace; This is a subjective decision on which theorists may disagree. Therefore, it is not always clear how the concept of balanced binary should be applied when section A is a point. However, if section A is a sentence, the balanced binary system can bring back the entire second half of section A (transposed if necessary) without ever bringing back the basic idea. If we put these ideas together, if the material is not alone between section A and the return of the thematic material (an excursus) and only part of section A returns, we do not have a ternary shape and can have a rounded binary shape, although not all theorists would accept this terminology (and there is some overlap here with the concept of balanced binary – see above). If we have a digression, but we also let the entire A section return, then according to the theorist, it could be called rounded binary or beginner ternary (meaning “approaching ternary”).

If the intermediate material presents itself as a self-sufficient section, then we have a small ternary section (in such cases, the entire section A usually returns). This type of notation indicated that both sections of the form had to be repeated. Also the repetition of editing with decorative improvisation for the second time is sometimes established. And sometimes decorative improvisation is not part of the score, but is expected in the performance. The rounded shape is also found in the first movement of Vivaldi`s Sonata No. 1 for cello and continuo. Another example is Air from Handel`s Water Music and J.S. Bach Minuet in G major, BWV Anh. 116. This is in fact a typical example of a rounded shape.

Sometimes, as in Domenico Scarlatti`s piano sonatas, the return of theme A may contain much of the original section A in the tonic, so much so that some of his sonatas can be considered precursors to the sonata form. The balanced binary is when the end of the first section and the end of the second section have an analogous cadential material (and arguably a precaddential material). The usual pattern for balanced binary elements is to emerge in a continuous binary form (i.e. a form in which the first section ends tonally), with both sections ending in “rhyme cadences” in which the same cadential material occurs in the two sections that are correctly transposed for their keys. This is different from the rounded binary because in a rounded binary form, the thematic material in section A must return to the end of section B (which usually happens at the beginning of sentences), while in a balanced binary, it is enough for a significant part of the end of the last sentence to return. J. S. Bach`s minuet is usually in binary form. It has two sections and each section is repeated. The repetition bars used make the end of each section obvious.

The first section begins on the G major tonic and moves before ending on the tonic. In classical music of the 17th and 18th centuries, each repetition of the binary form is usually repeated, as in Example 1.
