In your progress as composers, have you had a recent epiphany that has helped you bump your writing up a notch? Big or small, what was it?
For me lately, it is 6/3 chords. That is, chords with the 3rd of the chord in the bass. In common practice it's used to give a bass line a powerful melodic component. It is used in V-I or I-IV progressions where the third resolves up a half step. It's considered an unstable chord, and that's why it's use is temporary and very circumscribed. I don't know why I haven't used them before, they are very useful! They add a certain ambiguity and freedom to your voice leading.
Conversely, it doesn't have to be a major third. It can also be a minor third, which can be used as a stationary root. For example, the 6/3 chord Eb-G-C (Cm) can be interpreted as a Eb6 chord (I) going to Bb7 (V). Also many other possibilities with epiphanies, they don't have to be harmonic.
