But not always. A few seconds later in the theme, this situation is reversed: following the B-major tonic triad is a D-sharp-major triad, whose root is four semitones above. Yet this reversal of fortune is fleeting: B as tonic persists. These two moments – what I transcribed as the first and third measures – have something else in common, perhaps by design, perhaps by chance: the triad with its root four semitones above puts the fifth of the triad in the melody (F# in m. 1, A# in m. 3), and the triad with its root four semitones below puts the root of the triad in the melody (G in m. 1, B in m. 3).
This melodic-harmonic correspondence permits a kind of two-sided musical game in which each moment can be crossbred with the other. On the one side, the following recomposition depicts how the fleeting D sharp (respelled as E flat) could oust B as tonic, using B-major’s own tactics of clichéd subjugation and thematic banner-waving.
