I'm studying the Neapolitan Chord and the textbook includes the following excerpt to analyze. Up until measure 10 I understand what's happening, but I have no clue how to interpret measure 11 and onwards.
What I have so far:
- Measure 1 to 4 is the Tonic (f minor) plus a short section with the Dominant, the dominant is slightly extended here with a second inversion vii° chord.
- The end of measure 5 initiates the bII chord, which is tonicized up to measure 8, where it ends on its Dominant. Measure 7 contains a short extension of bII's Dominant using a second inversion vii° chord.
- Measure 9 is the Dominant of the Tonic again, C major. It's extended for 2 measures.
- The above creates Tonic - PreDominant - Dominant (I-bII-V), an almost complete phrase
But then measure 11 comes in and I feel lost. I see the following chords: - diminished natural e7 - minor b flat - C major (in the next measure) And after that, there's a longer passage with diminished natural e7 before we reach the end with a first inversion Db followed by a first inversion C.
I have no idea what's going on there. The e and b flat minor don't really work together as a Tonic-Dominant, which was what I first tried. I've tried seeing this as follows:
- e natural as some sort of tonicization of C major. But this doesn't work because it would be a iii° 7th, which is not a harmony I've seen in a major scale so far.
- e natural as vii°7. This was my best shot but that would go back to f. There is no f chord anywhere in the rest of the excerpt. It also doesn't work with the b flat minor 7th chord.
- tonicization of e natural. Given how e natural is also used in measures 14 and 15, this seemed like a good option but I also can't make it work because of its diminished nature. Its 7th prevents me from thinking of it as a potential tonic. Plus the b flat chord doesn't work because a) it's flat and it would push towards e flat, not e natural, and b) it's minor and lacks the push of a major Dominant chord.
- Assumed that the e natural moving to F in measure 11 could simply be a chromatic accent, and in turn make this be a G major 7th chord. Basically a V/V for the tonic (f). But the chord would be g minor, not G Major and again it kinda loses its quality as Dominant for C Major.
I just don't know anymore and I've wasted a couple of hours on it. Feel free to school me on this!
