I would be interested to see what happens when you do this to other types of music.

My team built something similar at a recent hackathon. It attempts to automatically do this to an arbitrary WAV file (break up into waveforms) and generate a new piece of music: https://github.com/osnr/markov-music

doesn't work for me if open in non-active tab in Chrome 22.0.1229.94 on Mac OS X 10.8 I can confirm this bug too.

That's just because Chrome throttles JS execution in background tabs to a crawl.

Thanks. Is there a fix?

You're close but not quite there. The build up is VI-natural VII-I-VI-natural VII-V7b9. So you have the chords right but the root note wrong. The major I for the third chord is the really key piece of that chord progression. Shifting up and down chords by step is pretty common in pop music, but shifting into major I the first time then the flat 9 dominant the second time (especially with the natural 7 right before it…

Thanks for the reply; I was wondering what key that it shifted to, since everything sounded weird when I tried it. I just do this stuff by ear and guess the key, but I've never had any music theory training. How do you recognize the key once you have the chords?

Pop songs rarely modulate, and if they do, usually modulate by step, so just find the root note and you have the key. Gangnam Style doesn't have any modulations unless you count the major I as a modulation. It definitely jumps out to the ear as something unusual.

For classical music the working key is constantly changing and often two theorists would disagree on the "harmonic meaning" of a passage. One telltale sign of a key change is an x-V-I progression (in the new key) where x is any secondary chord that leads naturally into the V. Bonus points if the x or the V don't work in the old key; if you're in C major and you hear a D7, you know something's up.

This isn't exactly a Markov model, although I reckon you could draw a mathematical connection.

It seems to me that it is. Please explain how the markov property is violated?

I'd guess each section is unique so there is no frequency analysis; the next section is picked at random instead of saying "Whoop whoop" is followed by "gundam style" 20% of the time, by "hey sexy lady" 50% of the time and by another "whoop whoop" 20% of the time.

What's unique about Gangnam Style is that it's a cultural meme in America that isn't in English. It would be really interesting to see what sort of different sentiment this project would inspire if applied to a song where Americans could actually understand the lyrics and cultural references, or if it was shown to a South Korean audience.

que sera sera. c'est la vie. There are lots of cultural memes in America that aren't in English. You can restrict to "recent pop culture", but even in straight music, 99 luftballoons was big 25 years ago. I'm sure there are many other examples.

Macarena, Las Ketchup and Numa Numa are three other recent ones (some contain English elements but the main catchy parts are in other languages).

Actually, this is a fairly unusual song, in music theoretical terms. Almost all pop songs use the I, ii, IV, V, and VI chords, with popular progressions including I-IV-V, ii-V-I, and I-V-VI-IV. Since this is tonal music, it obviously includes the I chord. It does use only four chords, but they are uncommon. Most of the song uses the I chord (G major in this case), but during the buildup, it uses an surprising I-II-II…

Your build up progression is exactly the same as mine, only I interpret it as based on the major key III. I agree we're not talking about modulation in the usual sense, but I think it makes sense to think of it as a key change. It reminds my ears of the common IV-V-vi progression, only with a suprising major VI.

I have to disagree again... I don't think a III chord is anywhere in the entire song. The build up is in the parallel major.

Right, the key III is the parallel major. I'm shifting the base of the notation for this passage. When I say III ends the build up, I mean III in the parallel major key, i.e. V(7) in the original key.

The electronic music and sugary pop beat. Also the irreverent fun on the video. Compare lady gaga music.

And it has its own dance. The Macarena, Cupid Shuffle, etc. are as popular for their dance as they are for the music.

It helps that the dance is both unique and easy to copy.
