I first became aware of this concept many years on Gary Garrett's blog, where he primarily refers to it as "the lattice." His introduction to the concept gives a brief history:

I also like this book which Gary recommends, although it's very challenging and I never made it all the way through:

A book that I came across the other day (via a recommendation from YT-ber Adam Neely): "Harmonic Experience" by W.A. Mathieu. It's a little expensive as a first dive into this stuff, but it does look like a very natural way to lead you into and through the actual experience of western tonal harmony, often by singing along with a drone (easy to generate on today's computers).

I remember getting Semiology of Graphics from the Palo Alto library around 2006. At the time it was sort of legendary and out of print, but it looks like it's since been reprinted. I think you can get most of the ideas from newer books, but it's well done and clearly ahead of its time.

Interestingly another relatively unknown book I like (and bought/read 20 years ago) is also about harmony:

https://www.amazon.com/Harmonic-Experience-Harmony-Natural-E...

I would say there's two kinds of harmony: harmony in equal temperament, and "alternative" harmonies based on physics, and this is about the latter. I can't tell from the link what the other harmony book is about. What's good about it?

As far as computer books, I've read a lot of recommendations here over the years like "thinking forth", "Computer Lib" by Ted Nelson, etc. They are well known to some audiences but not others.

I also enjoy reading what people though the computing future would be like. I have "Superdistribution" by Brad Cox:

And "Mirror Worlds" by Gelertner:

I'm pretty sure Gelertner claims that the Facebook feed is identical to his "life streams". I guess taken literally it's hard not to see the current Internet as a "mirror world" that's becoming the real world.
