I'm analyzing "When Christmas Comes to Town", which is one of my favorite holiday songs.
The image shows the last four measures of the bridge section. The bridge is in E♭-minor, while the rest of the song is in E♭-major.
I'm trying to figure out how to analyze the final two measures of the bridge section. The last measure seems to be a straight-forward ii7 - V7 back to I in the next measure.
There are two ways I thought of analyzing the final two measures:
The B7 (enharmonic to C♭7) almost seems to be acting like a Ger+6 chord, although it moves to ii7 (or ii7add11) before resolving to V7. The melody of the final measure of the bridge has the note B♭, which would be the note of resolution if the B7 is acting as a Ger+6 chord.
Another way I thought of looking at this was to consider the F♯m7 and B7 as a ii7 - V7 of ♭II (F♭-major, or E major), and this (eventually) resolves to the tritone substitution of ♭II (which would be a regular V7).
Do these analyses make sense? Is there a better way to analyze these measures that I haven't considered? I'd love to hear any thoughts on this. Thanks in advance, and happy holidays!
