AB Song Form consists of two or three verses alternating with a separate second theme music. This second separate theme is a section called the chorus. The bridge gives the listener a break from the main themes of a song. Usually, but not always, a bridge goes to a choir section. It should sound musically different from both the verse and chorus. It can contain lyrics or be purely instrumental. Example 4. A diagram of a ternary form in which only the first section of the form has its own complete form.

4 for an example. Although most Chopin nocturnes are in a general ternary form, the individual sections (either the A, the B or both) are often in binary form, usually of asymmetric variant. In this case, when a section of this binary structure repeats, it is rewritten in its entirety, usually significantly modified, rather than being enclosed between repeat characters. It can also be considered an extension of the ternary form or the binary form. The additional sections help distinguish it from other forms, especially those that only introduce new materials. Example 2: An abstract diagram of a composite ternary form in which all sections contain their own complete form. The first and most obvious form derived from AB is that of the song form VERSE/CHORUS/BRIDGE. The ABC song form can be difficult because your song can get long.
This becomes even more difficult when you consider that a commercially viable song should ideally be no longer than 3 minutes and 30 seconds. Although the content of each section can vary greatly in terms of sentence and form, each section often consists of several sentences, and very often these sentences combine to form a complete form (very often a binary form). A ternary form is considered composite if one or more of its sections include a complete musical form. If a section does not contain a complete form, it can be described as simple. In many composite ternary forms (such as Minuet & Trio or Scherzo & Trio in particular), all sections contain complete forms (often rounded binary forms). However, in 19th century composite ternary forms, the last section A is often shortened and is simple, not composite. In zone C, an entirely new material is introduced. Each of the choruses can be thematically and tonally different, which makes the shape of the rondo so unique. The through compound form is a composition that is completely continuous. Each great thematic material is not repeated, and each section sounds like something completely different.
An example of this would be ABCDE. The binary form is a musical form in 2 related sections, which are usually repeated. The binary is also a structure used to choreograph dance. In music, this is usually performed as A-A-B-B. As with the other forms, each section can be described as harmoniously open or closed. Now that you have the different musical forms under control, it is important to understand that there are other variations of each form. Each form can be customized to grow, condense, or somehow switch to a new form. Below is a list of other forms you may encounter in the musical compositions you analyze. In rounded binary form, the rules generally remain the same. The difference is that more material is added to Section B. This material is taken from part of section A.
Unlike the ternary form, it is not a completely new section. The sonata form is a musical composition divided into three distinct sections. The sonata form consists of: Its structure is identical to that of the song AB, except that a bridge is inserted into the structure of the song. The bridge should be lyrically and rhythmically different from the verse and ideally provide the listener with a reason to repeat the chorus. Modulation is possible within each section in ternary form, but it is very rare in section A and should be considered atypical if it is there. Modulation in the B scale is much more common in an aria than in dance forms such as minuet and trio. The second section of a ternary form, usually referred to as section B, should provide a contrast with section A that preceded it. This contrast can come from a variety of musical domains, including tonality, mode, texture, time signature, rhythmic ideas, melodic ideas, scale, instrumentation, registers, etc. However, it is generally expected that the length of B will be proportional to that of A. It is important to understand how the musical form works because it is the basic structure of an entire work.
In this article, we will analyze each form, give a clear definition, examine some specific examples and also the purpose of each musical form. Let`s start with the strophic form. For example, if section A is a period (using Caplan`s naming conventions; elsewhere referred to as a parallel period), the first sentence („antecedentary“) of section A begins with a basic idea (usually for half the sentence) and ends with a relatively low cadence, and the second sentence („coherent“) begins with the same basic idea and ends with a stronger cadence; Alternatively, 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 move to a cadence. In a rounded binary form, at the end of section B, if section A were a sentence, typically the beginning of the sentence returns, possibly truncated, followed by the cadence; If it`s a point, so is it, but since the previous one and the sequence of a point both start in the same way, it`s usually easier to say that the whole tracking phrase comes back. In both cases, however, the basic idea returns, followed by the cadence. In a balanced binary, the basic idea doesn`t have to come back. There is room for discussion about how much material must be returned before the cadence; This is a subjective decision on which theorists may disagree. Therefore, it is not always clear how to apply the concept of balanced binary when section A is a point. However, if section A is a set, the balanced binary can bring back the entire second half of section A (transposed if necessary) without ever bringing back the basic idea. Mood is also an important feature of the ternary form.
The first section can be fast and lively, while section B is quiet and less intense. Composers who use this form go to great lengths to ensure that Section B has a clearly defined character that allows each section to sound like their own separate compositions. This article explains AB Song Form or VERSE-CHORUS Song Form, ABC Song Form or VERSE-CHORUS-BRIDGE, all common derivative song forms and video examples of these song forms used in current popular songs. Many examples of rounded binaries can be found among Vivaldi`s Church Sonatas, including his Sonata No. 1 for cello and basso continuo, first movement, while some baroque composers such as Bach and Handel rarely used the form. [6] Bela Bartok used it frequently in his string quartet music, especially in the fourth and fifth. He is also present in his Second Piano Concerto. Samuel Barber also used the bow shape in his Adagio for strings. The shape of the arch is essentially a rondo shape, but symmetrical.
It is also common to see a strophic form represented in blues music, singing, and in some cases, classical music. It actually works a lot like the ternary form, and it`s easy to confuse the two. Exhibition and development have very different themes and key areas. Each half of the mold is harmoniously closed. Exposure is considered the first half, while development and recapitulation are considered the second half. A much broader version of the ternary form is called the composite ternary form. Sometimes Section B ends with a „return“ of the opening material from Section A. This is called a rounded binary and it is called an ABA`. In the rounded binary, the beginning of section B is sometimes called a „bridge“ and usually ends with a half-cadence in the original key. The rounded binary should not be confused with the ternary form, also called ABA – with the difference that in the ternary form, the B section contrasts completely with the material A, as for example in a minuet and trio. Another important difference between rounded and ternary forms is that in rounded binary form, when section „A“ returns, it usually contains only half of the complete section „A“, while the ternary form ends with the complete section „A“.
An example of the strophic form in a folk song would be „The Wheels On The Bus“. An anthem like „Amazing Grace“ or even a simple children`s melody like „Mary Had A Little Lamb“. If you are unsure of the meaning of certain terms, please consult our music glossary. The first bars of section C sound the same as section B, but in the form of an ABAC song, the melody turns into something completely different. AB has been the songwriting format of choice for modern pop music since the 1960s. It is often used in love songs, pop, country, rap and rock. Unlike the AABA, or AAA, form, which both highlight the verse, the AB format focuses entirely on the chorus. Although the AB Song form has existed since the mid-nineteenth century, the most popular songs of the classic rock era are written in the AB Song form.
