Interesting! Embedding data in music using redundant bits, sure. But using notes? But you'd need to make sure that it didn't sound too strange.
Yes, there shouldn't be "there's something strange with this music" moment for listener. I agree with her last statement:
Schoenberg making a comeback? Would be rather fitting since the fascists thought his music was degenerate. As an extension, you could probably instead code chords and chord progressions to make the music sound more palatable.
Well, there's already lots of math in Bach's stuff. So something derivative with embedded code wouldn't be hard.

Tho western heptatonic scale has its origin in Pythagorean tuning and it fits very well to the nature of overtone, theories of western classical music is more of a collection of rule of thumbs. One actually applied math to this field is Xenakis, but Boulez also is good at math and emphasized mathematical nature of music. Schoenberg still keeped some construction & his style, so those who're familiar with modern western music might feel sth strange. But if one encoded sth in music made in the style of John Cage's Music of Changes, I think 100 ppl out of 100 won't feel anything strange. Anyway, very interesting. Thank you for posting and I'll read full article.
