The article title is obviously nonsense, but the theory and implementation are certainly interesting.

No takers?

The takeoff point of the Chew-Chuan analysis is one on which much recent music theoretic work is based — the work of 19th century German theorist Hugo Riemann, who rethought the old ideas of harmony, creating new ways of representing rules that make some, but not all, rhythmic successions of overlaid notes sound musical. Riemann's representation has only recently been applied to rock music.

The ASSA analysis looks at the tree of possible accompanying chord sequences, and analyzes which branches are followed, treating the unfolding string of possibilities as a Markov series – that is, a temporally ordered series of states (in this case, chords) in which chord determines its successor.

The resulting system thus has two elements. One is analysis of complete, accompanied music samples for what (neo-Riemannian) harmonic progressions they tend to follow. The second is taking these derived stylistic rules and using them to generate accompaniment -- using a Markov series -- for a user-provided melody.

-------------------------------------

Then, chords are prescribed at checkpoints in the melody where [the system finds] the harmony unambiguous. "Using these checkpoints as anchors, we use neo-Riemannian transformations to build chord progressions between checkpoints. Finally, we use Markov chains to generate the final chord progression."

I prefer to make music my own self. I like Rosie the Robot on the Jetsons as much as the next person, but I don't want her to be 'makin' mah beats', if ya know what I mean.

being part machine im open to the idea of completely mechanised music.

Oh, I'm not the slightest bit interested in copying "styles" this way.

I'm interested in the nerdy algorithms and the possibility of really, really confusing the hell out of it to make scary hybrid monster arrangements.

Feed it vurt's Feathers, pattonfreak's Download Of The Year and Carrol King's Tapestry and see what comes out.

me neither, im interested in hearing what "dalek" music might sound like, pure logic, will it be art? is the coding itself the art?
it could indeed all sound very clinical, but just imagine that one possibility of an idea ...

well, that's because you have an active imagination. pervert.

My thought is that this encourages not imagination.

Put Dr. Teeth and the Electric Mayhem with Leonard Chohen 80's synth era songs like Take This Waltz.

How does a program parsing chord progressions get you there from here, though?

I understand the interest in the coding, I do. And you guys' 'esoteric' approach is laudable, I just suspect programs made to do people's work for them; on a historical - cf. HG Wells - basis.

I'm so not modern.

sadly, it may not get anywhere near my thoughts, but i cannot discount the possibility, if i did that i would have to do the same with many of my ideas for a brighter future, if this is it, i don't want it.

and i suspect many will use it as you imagine, but that does not mean we have to.

not sure i am, if i was maybe i'd understand its limitations a little more, as it is im an excited little child waiting for robot moozak

Well, I don't have that big a brain, or am so calcified, to understand how to use things other than out-of-the-box. What they're made to do.

I can think logically sometimes, but when it gets into symbols, I get a headache.

As aesthetics goes, I'm not real into hearing a noisy mish-mash of pop styles though, which is another subject.
And, me, I have to discount possibilities... it's an economy of means argument, now that I mentioned aesthetics.

And then I'd put a rachMiel track, a jancivil song, and Urban Dance Squad into the blender and render the resulting midi score with jobro's Good GM VSTi.

I think it's appaling that people might use such a thing to write a song "in the mode of Brian Wilson" or Nancy Sinatra or whomever. As though people don't already do that too much.
