Inversions, part 2

This continues discussion of inversions of the major dominant ninth chord.

Apologies for the overlapping boxes in this graphic of the opening of Franck's Violin Sonata. Boxes 1 and 2 include the second inversion of A: V9, each sandwiched between root position chords. The third "clears out" the chord momentarily by reducing it to a root position B minor triad.


Here is a passage from later on. The sounds over C#3 vary, with C#9 briefly touched in the third bar, though against a dissonant passing tone in the violin. The fourth bar gives us a#ΓΈ7, which becomes the upper part of the F#9 a bar later.


Now a secondary dominant ninth in its second inversion (MacDowell, To a Wild Rose). I've added the slurs in the bass to bring out the pattern in the harmonies: consonance to dissonance over the same bass in bars 1-2 & 3-4, then the reverse in bars 5-6 & 7-8.


And two examples of the unfolding bass figure: Sousa, Hail to the Spirit of Liberty, trio; James Scott, Broadway Rag. In the latter the boxes and arrows point to the common parallelism in a figure over V9, then over Iadd6.



For the third inversion, a waltz by Alexis Castillon and the introduction to An der Elbe, op. 477, Johann Strauss, jr.'s last published waltz set. There is expressive emphasis in Castillon's version, but as a harmony it is undercut by its middle position in a dominant.


In the second box below, a clever parallelism with a reversed harmonic progression, because of which the ninth (G5) resolves internally.

The best example for the third inversion, though, is in the "Serenade of the Doll" from Debussy's Children's Corner. Here is the second of three divisions of the B-section; it is made entirely of major dominant ninth chords, 15 of them, 9 of which are third inversions (indicated by asterisks (*)).


By way of a postscript: in the third division of the B-section, the F#9 returns to initiate a traditional cadence progression: E: V9/V drops the sharp to become ii13, then follow V7 and Iadd6:
