Complete the following chord progression in four voices. Provide a syntactic analysis below the Roman numerals. The syntactic analysis is shown below the Roman numerals. The voicing of chords and voice leading between chords is variable. Brain Teaser What triad is shared by V7 and viiØ7? How do these two seventh chords differ in terms of their scale-degree contents? Answer: V7 and viiØ7 share the leading-tone triad (viiO). The two chords differ by 5ˆ (the root of V7) and 6ˆ (the seventh of viiØ7). 5ˆ and 6ˆ are a whole step apart (a half step in minor, where 6ˆ is the seventh of viiO7). Thinking Critically An incomplete triad or seventh chord is missing its fifth. Compared with other chord members (root, third, and seventh), why is it possible to omit the fifth (i.e., why is this particular chord member nonessential)? Discussion The root of a chord is necessary to identify the chord and its function, the third determines the quality of the chord (major or minor), and the seventh must be present for a chord to be an actual seventh chord (rather than a triad). The fifth fills out the harmony but does not impact function or quality. One exception is viiO (and iiO in minor), where the fifth is largely responsible for the diminished quality of the chord. © 2019 Taylor & Francis.
