What does the term "binary form" indicate about a musical composition?

The term "binary form" specifically refers to a musical structure that is organized into two contrasting sections, often labeled as A and B. Each section usually presents distinct musical themes or ideas, further defining the contrasts between them. This form is prevalent in various musical styles and is characterized by its straightforward yet effective ability to create structure and contrast within a composition.

The emphasis on two contrasting sections allows for a clear development of musical ideas, making binary form a fundamental concept in music theory. While some binary compositions may have repetitive elements within their sections, the defining characteristic is the presence of two different sections rather than just repeating material or adhering strictly to a melody or vocal focus.
