The Ternary Form is one of the early music forms that composers have created in the 16th century of the Western music. Ternary means three portions. This type of music usually has only Part A and Part B. These two parts are related, but not the same. Usually, the portions of music are related by melodic or rhythmic ideas, sometimes both. After Part B is presented, Part A with its entirety would be repeated once again. Therefore, the Ternary Form is also called the "ABA Form."
One of the most famous songs in the world is called "Twinkle, Twinkle, Little Star" in English. More song titles have been created by using this melody, such as "Baa, Baa, Black Sheep." This song has three portions. With the first (M.1-4) and last (M. 9-12) portions being identical, only the second (M.5-8) portion has a different melodic line but using the same rhythmic pattern. The color-coded notation helps to identify the notes and pitches.

Here is another example of the Ternary Form. In this case the music is written like a Binary form, but a repeat, D.C. al Fine (From the Top to the Finish sign) is definitely necessary at the end to create that "ABA Form", or Ternary Form.
Telemann's "Rigaudon" has three portions, even though it looks like two portions only. With the repeat sign at the end of the page, it made the song another 8 measures longer; therefore, an "ABA Form."
