From "The music theory of V A P O R W A V E" where Adam Neely not only explains and critiques Vaporwave but takes a big steaming dump on it by creating the track that captures and parodies its entire aesthetic.
He got his source material directly from this archive.org collection, as it says in the opening titles:
"On October 2, 2015, Mark Davis posted his prized collection of digitized K-mart elevator music cassette tapes to archive.org, free for anybody to use.
I thought this remark in the comments was pretty interesting:
> Something that helps identify Vaporwave is the natural vibrato that occurs from using tape cassettes etc. I often wonder if vibrato, as an effect, gains it's ability to evoke emotion through a psychological connection with the natural vibrato of a person's wavering voice while near to crying. If so wouldn't that be a potential factor in this kind of music's popularity?
It's a good video, but I wouldn't go anywhere near as far as saying he's taking a "big steaming dump" on it. He takes pains to explain why the experience of listening to a piece (accounting for the emotions that a given piece evokes) takes ultimate priority, and the trappings of classical music theory only follow from there. To a listener it doesn't particularly matter if a piece of work is unserious, amateurish, low-effort, etc. if the emotions that it evokes are genuine, and nostalgia is a legitimate emotion to evoke, and sampling from period-appropriate music only enhances that effect.
