Hi guys, here’s a follow-up to the Jazz Standards - Ballads Harmony Workshop on the topic on ‘descending diminished’.
As mentioned in class, we were looking into the second chord on ‘Smoke Gets In Your Eyes’:
As we know, diminished chord has tension, and is always related to a dominant (V) chord. In this case as well.
With a first look it seems weird how F#/Gb dim can resolve to F-7, and actually directly it doesn’t. Let’s look at the chord and to what dominant derives from it:
But of course, F7 doesn’t resolve to F-7 directly. However, it resolves to Bb, in this key being the V (Bb7 → Ebmaj). So, F#dim in this case is actually resolving to the Bb7, making it a secondary dominant, a V of V. And because we should treat II V as a one thing, not separating the two chords from each other, we can resolve the V of V (in this case F#dim) to F-7, taking that it is followed by Bb7.
Here also are two tutorials where I’m talking about the subject:
And more advanced (starting ca. 1:40):
Let me know if you have any further questions!
All the best,
