with G in the bass, shown below in Example 4.9. As with the G minor that never arrived, C minor would have been closely related to the home key. This time, however, it would have been as its submediant instead of its mediant. Finally, landing on C minor instead of C major would have avoided the enharmonic paradox on pitch-class 4. Beginning of B section mm. 32 – 33 c: VI V11 I C minor anticipated C major arrives (A¼ and E¼) Example 4.9 Poulenc, Piano Concerto, second movement, first part of B section, mm. 32–33, anticipation of the minor mode and unexpected arrival of C major The primary key areas of this first part of the B section, C major, E major, and A¼ major, are summarized in Example 4.10. The keys tonicized for a shorter duration, shown as quarter notes, are included to show relationships with the main keys. Justification for relating C major back to G major, instead of giving it its own major- minor complex, will be given below. 131 B section (part 1): Mm. 33 35 37 40 45 46 transition first theme 1 2 E¼/e¼: (key of IV or iv……………..........) G/g: IV A¼/a¼: ii i VI i I Example 4.10 Poulenc, Piano Concerto, second movement, key relations in the first part of the B section Parallel modes and the chromatic mediants they support thwart expectations and emerge as the main point of tension for the entire movement. The second half of the B section has the loudest dynamics in the movement thus far, with fortissimo and fortississimo entrances of the theme, double-dotted rhythms, flights into the high registers in the solo part, and frequent harmonic moves to remote keys.
