explain ternary form

what have played/sound in this structure

thanks for your help!

Ternary form is a musical structure commonly found in classical music. It is often designated as ABA, where "A" represents the first section, and "B" represents the contrasting middle section.

In ternary form, the music generally starts with the A section, which establishes a melodic theme or musical idea. After the completion of the A section, the music moves on to the contrasting B section, which introduces new material, perhaps a different key, or a change in mood or texture. Once the B section concludes, the music then returns to the A section, creating a sense of symmetry and closure.

To determine what is usually played or sounds in this structure, we need to consider the style or genre of music being discussed. Ternary form can be found in various musical compositions, such as classical symphonies, sonatas, minuets, or even some popular songs.

In a classical symphony, for example, the A section often features the exposition of a main theme, while the B section may explore different themes or provide a harmonic contrast. When the music returns to the A section, it may be restated in a slightly varied or developed form.

In a minuet, the A section can present a dance-like theme, while the B section might offer a contrasting melody or rhythmic pattern. When the A section comes back, it usually remains relatively unchanged.

In popular songs, the A section commonly includes the verses, while the B section is typically the chorus, creating a catchy and contrasting part. The return to the A section brings familiarity and reinforces the main theme.

To identify specific examples of music that follow ternary form, it would be helpful to provide more information about the time period, composer, or particular piece you are interested in.
