The ‘Anchoring vi Schema’ and its relation to phrase rhythm in popular music

Abstract

Abstract In order to reveal normative prototypes undergirding various formal sections, this article introduces the ‘Anchoring vi Schema’: a medium length major-mode passage (typically eight or 16 bars) that initiates on an unambiguous hypermetric downbeat (for example, the beginning of a verse or chorus). The Anchoring vi Schema must begin with tonic harmony and deploy submediant harmony at its midpoint – the second most hypermetrically strong beat. The identification of the Anchoring vi Schema enables closer readings of phrase expansion and deletion in popular music. A comparison of the common harmonies used in eight- and 16-measure passages reveals some striking similarities, particularly in terms of where tonic and subdominant chords are likely to occur. Although the endings of formal sections can take a variety of paths – including arriving at various tonal goals within a range of possible times – hypermetrically accented beginnings and midpoints show greater consistency in their organisation.
