This was fun, although you could probably follow at this speed only if you already knew this material.

I note there was very little on Sus chords such as 9sus or 13sus, and no mention of the elusive Sus2 which I think is actually correct to omit. In BIAB, a 2 chord, an add2 chord, and an add9 chord are all the same.

One area that perhaps deserved just a few more seconds is the Alt chord. While everything said here is true, it should be stressed that the Alt chord can be one of several combinations with the dominant seventh, remove the perfect fifth, and then add a sharped or flatted five AND/OR sharped or flatted ninth.
