Forms with Contrasting Sections • “Forms with multiple, identifiably distinct sections (called formal sections). The different sections in such forms often contrast with one another musically. For example, there may be a modulation from one key to another, a change in the chord progression or instrumentation, or a change in the meter or rhythmic structure from one section to the next. Often, multiple changes such as these will occur simultaneously.” (p. 82) • Verse-chorus form among the most common • Shawn Mendes, “There’s Nothing Holdin’ Me Back” [PL 6-15] • Devi Lovato, “Sorry Not Sorry” [PL 6-16]
“Ingculaza (AIDS)” [PL 6-17] • Dumisani “Ramadu” Moyo (Zimbabwe) • Verse-chorus form • Intro, Verse 1, Chorus 1, Verse 2, Chorus 2, electric guitar solo (“replaces” Verse 3), Chorus 3 (“looped” at end) • Follow along with form chart on p. 84 while listening • Portion of song text (translated from Ndebele language) Everybody in my village is crying about you You have taken away my sisters, brothers and innocent souls including children What shall we do? How should we behave? The answer is simply to “prevent rather than cure” in order to have a healthy community with a good life and a happy future.
