"Over the Rainbow" (Arlen/Harburg) exemplifies the 20th century popular 32-bar song.[1]

The thirty-two-bar form, often called AABA from the musical form or order in which its melodies occur, also ballad form,[2] is common in Tin Pan Alley songs and later popular music including rock, pop and jazz. Though it resembles the ternary form of the operatic da capo aria its popularity declined and "there were few instances of it in any type of popular music until the late teens" of the 20th century. It became "the principal form" of American popular song around 1925–1926,[3] with AABA form consisting of the chorus or the entirety of many songs in the early 20th century.[4]

Some Tin Pan Alley songs composed as numbers for musicals precede the main tune with a "sectional verse" that is usually sixteen bars long. The verse establishes the background and mood of the number, and is musically undistinguished in order to highlight the attractions of the main tune. The main tune—usually a classic AABA thirty-two-bar form—is called the refrain or chorus. The sectional verse is often omitted from modern performances, and thus the refrain is often the only section remembered and heard.

In the refrain, the A section forms the main melody and establishes the home key. This section is always repeated; sometimes the pair of As are contrasted as musical question and answer, and in other cases they are identical. The B section or middle eight is also often referred to as the bridge and sometimes as the release.[5] Most B sections begin with a departure from the home key (usually by establishing the "subdominant" harmony (IV), and end on an unresolved dominant chord of the home key, preparing for the return of the verse.[6]

"In this form, the musical structure of each chorus is made up of four eight-bar sections, in an AABA pattern... Thousands of Tin Pan Alley tunes share this scheme and Adorno is quite justified in arguing that to listeners of the time it would be totally predictable."[7]

Thirty-two-bar form was often used in rock in the 1950s and '60s, after which verse-chorus form became more prevalent. Examples include:

AABA form in Willie Nelson's "Crazy" chorus: each phrase is eight bars.[9] About this sound Play 

Though more prevalent in the first half of the 20th century, many contemporary songs show similarity to the form, such as "Memory", from Cats, which features expanded form through the B and A sections repeated in new keys.[5] Songwriters such as the Brill Building and Lennon-McCartney also used modified or extended thirty-two-bar forms, often modifying the number of measures in individual or all sections. The most prominent of these is "Yesterday", which adapts the familiar tin-pan alley melodic structure in a subdued manner by minimizing the harmonic contrast at the end of the B section. In "Down Mexico Way" "the A sections … are doubled in length, to sixteen bars—but this affects the overall scheme only marginally".[8] Joni Mitchell's "Marcie," compounds the form, with most stanzas presenting a conventional (but short) AABA, the third and fifth contrasting that with a clear bridge; in total: AABA,AABA,CDCE,AABA,CDCE,AABA. Compound AABA form can also be found in The Police's "Every Breath You Take" (1983), features a thirty-two-bar section, a contrasting bridge and then a repeat of the thirty-two-bar section, making a compound of ABA and AABA form: AABACAABA: a form of rondo. Mitchell's "Night Ride Home", Tom Petty's "Refugee" (1979)[10] and Michael Jackson's "Out of My Life" and "The Way You Make Me Feel", and Bob Dylan's "To Make You Feel My Love" present more straightforward examples of the form that are nevertheless not typical of the late 20th century.

Middle eight[edit]

In music theory, middle 8 or bridge refers to the B section of a thirty-two-bar form.[11] It is often a passage from the tonic into the dominant, often subdominant,[12] or a major or minor key (see modulation (music)).[11]

This section has a significantly different melody from the rest of the song and usually occurs after the second chorus in a song (typically, a song in thirty-two-bar form consists of first verse, chorus, second verse, chorus, middle eight, chorus).[citation needed] Such sections often consist of new chords, but also frequently just alternate between two chords. It is called a middle 8 because it happens in the middle of the song and the length is generally 8 bars.

Middle 8s are often quieter than the main song, which contrasts with solos, which are generally more energetic. In slower songs, however, a middle 8 can be used to generate energy. By adding a powerful upbeat middle 8, musicians can add a great hook for an end chorus and finale.
