Various chords realized in “chorale style” with equal distribution of notes in bothhands.Model VII uses two voices per hand and employs different four-, five- and larger-partharmonic structures. Since this model uses only four-voice textures, larger formations needto be reduced to their essential harmonic frameworks. In reducing chords to their four-part frameworks certain notes are retained and others omitted. Typically, the root isretained, the 5th is omitted, and—depending on the context—the remaining three voicesare selected from the related guide tones, pitch alterations, or extensions. Figure 12.7demonstrates different Model VII realizations of the II–V–I progression. The selectionof chords differs from one realization to the next and depends both on the voicing of theopening chord and on the voice-leading forces initiated by the initial two chords
