Mysterious Aug 5th

In this video I talk about the mysterious augmented 5th interval.
This video has a very long rabbit hole around the two minute mark. The important things are before the rabbit hole. May want to go with the rabbit to find out why this subject is so difficult for students.

For those coming in from outside with some background: The bulk of this seems to involve the augmented chord - the two outer notes are our "augmented 5th" but can also appear as the "minor 6th". Having a universal name ("quad" = 4 whole tones) is a good way to see it as is. Also, traditionally taught, we expect too much to always see the snowball and a literal "aug5". This here helps dispell the fog.
I like starting with a whole tone scale, because if we have that scale under our fingers, it is easy to recognize anything comprised of a number of whole tones. It's like a concrete visual, tactile, and aural measuring stick.
