Q: What are some cool ways that an aug chord could be used, perhaps an example from some music you like or have written?
A: if you get in a time machine and go to the late 70s and check out some minor key r&b songs, i think you may find that the 5 chord will be something like this: say it's the key of C minor, you're gonna see something called Gaug7 which has G in the bass and then it has F, B, and Eb in the chord. but this is not quite the thing you are talking about, although it is more common than the thing you are talking about. and it is still used today not just in the 70s
