seventh-chords, through his analysis of Lizst's Faust Symphony.157 The combination of two
augmented triads, one major third apart, results in an augmented seventh-chord in which the root
and the seventh were enharmonic pitches. For example, Ab-C-E and C-E-G# combine into the
seventh chord Ab-C-E-G#, where Ab and G# have an enharmonic relationship. This is, of
course, different from the usual understanding of an augmented seventh-chord such as Ab-C-E-
G. I have reinterpreted Ogolevets's original figure in Example 3.8.158
Example 3.8: My reinterpretation of Ogolevets's derivations of the augmented seventh-chord.

The bracket above the top stave highlights the augmented seventh-chord, Ab-C-E-G#, in
open noteheads. The short, curved arrows, stemming from each member of the seventh-chord,
link to a semitone above and below each of these members (shown as darkened noteheads). From
the first half of the augmented seventh-chord, Ab and C, Ogolevets derives the semitones below
(to the left side)-G and B-into a new "hybrid" collection on the stave below. Downward
pointing arrows illustrate this derivation. From C on the top stave, however, he includes both of
the semitones above and below (B and Db) to produce first hybrid triad (outlined with a dashed
