described as AABA, this does not mean that the A sections are all exactly the same. The first A section ends by going back to the next A section, and the second A section ends and transitions into the B section. As such, at the minimum, the composer or arranger often modifies the harmony of the end of the different A sections to guide the listener through the key changes. As well, the composer or arranger may re-harmonize the melody on one or more of the A sections, to provide variety. Note that with a reharmonization, the melody does not usually change; only the chords played by the accompaniment musicians change. Examples include "Deck the Halls": A: Deck the hall with boughs of holly, A: 'Tis the season to be jolly. B: Don we now our gay apparel, A: Troll the ancient Yuletide carol. Variation on the basic structure 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". Also "Old MacDonald", "Amazing Grace", "The Thrill Is Gone", and Gordon Lightfoot's "The Wreck of the Edmund Fitzgerald". 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". 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). 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". 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". Variations include Smokey Robinson's "My Guy", The Beatles's "Ticket to Ride", 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).
