Song structure
Song structure is the arrangement of a song,[1] and is a part of the songwriting process. It is typically sectional, which uses repeating forms in songs. Common forms include bar form, 32-bar form, verse–chorus form, ternary form, strophic form, and the 12-bar blues. Popular music songs traditionally use the same music for each verse or stanza of lyrics (as opposed to songs that are "through-composed"—an approach used in classical music art songs). Pop and traditional forms can be used even with songs that have structural differences in melodies. The most common format in modern popular music is introduction (intro), verse, pre-chorus, chorus, verse, pre-chorus, chorus, bridge, and chorus. In rock music styles, notably heavy metal music, there is usually one or more guitar solos in the song, often found after the middle chorus part. In pop music, there may be a guitar solo, or a solo performed with another instrument such as a synthesizer or a saxophone.
The foundation of popular music is the "verse" and "chorus" structure. Some writers use a simple "verse, hook, verse, hook, bridge, hook" method. Pop and rock songs nearly always have both a verse and a chorus. The primary difference between the two is that when the music of the verse returns, it is almost always given a new set of lyrics, whereas the chorus usually retains the same set of lyrics every time its music appears."[2] Both are essential elements, with the verse usually played first (exceptions include "She Loves You" by The Beatles, an early example in the rock music genre). Each verse usually employs the same melody (possibly with some slight modifications), while the lyrics usually change for each verse. The chorus (or "refrain") usually consists of a melodic and lyrical phrase that repeats. Pop songs may have an introduction and coda ("tag"), but these elements are not essential to the identity of most songs. Pop songs often connect the verse and chorus via a pre-chorus, with a bridge section usually appearing after the second chorus.
The verse and chorus are usually repeated throughout a song, while the intro, bridge, and coda (also called an "outro") are usually only used once. Some pop songs may have a solo section, particularly in rock or blues-influenced pop. During the solo section, one or more instruments play a melodic line which may be the melody used by the singer, or, in blues or jazz improvised.
Variation on the basic structure[edit]
Verse-chorus form or ABA form may be combined with AABA form, in compound AABA forms. That means that every A section or B section can consist of more than one section (for example Verse-Chorus). In that way the modern popular song structure can be viewed as a AABA form, where the B is the bridge.
AAA format may be found in Bob Dylan's "The Times They Are a-Changin'", and songs like "The House of the Rising Sun", and "Clementine".[21] Also "Old MacDonald", "Amazing Grace", "The Thrill Is Gone", and Gordon Lightfoot's "The Wreck of the Edmund Fitzgerald".[22]
AABA may be found in Crystal Gayle's "Don't It Make My Brown Eyes Blue", Billy Joel's "Just the Way You Are", and The Beatles' "Yesterday".[23]
ABA (verse/chorus or chorus/verse) format may be found in Pete Seeger's "Turn! Turn! Turn!" (chorus first) and The Rolling Stones's "Honky Tonk Woman" (verse first).[21]
ABAB may be found in AC/DC's "Back in Black", Jimmy Buffett's "Margaritaville", The Archies's "Sugar, Sugar", and The Eagles's "Hotel California".[24]
ABABCB format may be found in John Cougar Mellencamp's "Hurts So Good", Tina Turner's "What's Love Got to Do with It?", and ZZ Top's "Sharp Dressed Man".[24] Variations include Smokey Robinson's "My Guy", The Beatles's "Ticket to Ride",[21] The Pretenders' "Back on the Chain Gang" (ABABCAB), Poison's "Every Rose Has Its Thorn" (ABABCBAB), and Billy Joel's "It's Still Rock and Roll to Me" (ABABCABCAB).[24]
