- grinich 14y agoMarkov models work well for almost every genre-- recompositions of classical or modal jazz tunes are particularly awesome.
- mistercow 14y agoThis isn't exactly a Markov model, although I reckon you could draw a mathematical connection.
- im3w1l 14y agoIt seems to me that it is. Please explain how the markov property is violated?
- DrStalker 14y agoI'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.
- zbyszek 14y agoSurely in a Markov process the next state is picked at random with some probability distribution, which may be uniform.
- mistercow 14y agoYeah, thinking about it some more, that seems to be correct. It isn't what people usually think about when they think about Markov models, but it qualifies. Actually, I think this kind of Markov model might be a better introduction than some of the others I've seen, since it's extremely simple to understand.
- iamwil 14y agoI clicked through to his blog, and apparently, it was inspired by "James Brown Forever" http://nest.echonest.com/post/526547218/james-brown-forever-is-back http://nest.echonest.com/post/526547218/james-brown-forever-... I don't know his music well enough to tell it's a mix. Maybe you can.
- osnr 14y agoMy 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 https://github.com/osnr/markov-music
- Aissen 14y agoJust tried it on a music I liked, and wanted to create an "inifinite" version for some time: http://soundcloud.com/college/college-teenage-color http://soundcloud.com/college/college-teenage-color (echonest track id: SOGUHNN12A8C13E7DD) It doesn't work as well as in gangnam style. I didn't take time to try to understand why. Either this is because echonest's analyzed mp3 isn't the same as mine. Or the function to compute distance between beats isn't generic enough.
- brianwhitman 14y agoAnalyze your own, it'll be much better when you're doing synchronous stuff like this. Our canonical audio is likely very different in bitrate or time to start.
- IsaacL 14y agoI did a university project in Clojure that fed Final Fantasy midi tracks into a Markov chain. https://github.com/IsaacLewis/MidiMarkov https://github.com/IsaacLewis/MidiMarkov The crystal theme worked the best (it's basically some scales on the piano that go up and down). With a first order Markov chain, the output was a random walk of notes going higher and lower. With a second order chain, the notes went up and down fairly steadily, but with scales peaking at odd points. With a third-order chain, you get close to the original song out. (It's hard to explain in text, without knowing the correct music vocabulary, but I hope you get the idea).
