Delia Derbyshire, Alchemist of Sound

The amazing Delia Derbyshire, pioneer of British electronic music, demonstrating tape loops. A clip from the documentary "Alchemists of Sound" on the history of the BBC Radiophonics Workshop, where Derbyshire worked from 1962-1973.

Derbyshire is best known for her realization of the original Doctor Who theme-- from Wikipedia: Derbyshire's interpretation of Grainer's theme used electronic oscillators and magnetic audio tape editing (including tape loops and reverse tape effects) to create an eerie and unearthly sound that was quite unlike anything that had been heard before. Derbyshire's original Doctor Who theme is one of the first television themes to be created and produced by entirely electronic means. Much of the Doctor Who theme was constructed by recording the individual notes from electronic sources one by one onto magnetic tape, cutting the tape with a razor blade to get individual notes on little pieces of tape a few centimetres long and sticking all the pieces of tape back together one by one to make up the tune. This was a laborious process which took weeks.

From her web site: A recent Guardian article called her 'the unsung heroine of British electronic music', probably because of the way her infectious enthusiasm subtly cross-pollinated the minds of many creative people. She had exploratory encounters with Paul McCartney, Karlheinz Stockhausen, George Martin, Pink Floyd, Brian Jones, Anthony Newley, Ringo Starr and Harry Nilsson.

Jazz organ: great instrument, or the greatest instrument?

breve

breve is a free/open-source 3d environment for multi-agent simulations and artificial life, which can be used to simulate things like BZ reactions, evolution by natural selection, and the flocking patterns of birds (which by the way is a good example of how realistic behavior can be produced using a drastically simplified model).

Also on the site is the breveCreatures screensaver, a simple simulation of evolution by selective pressure which you can download on its own. Creatures are initiated as random configurations of moving blocks, and selected through successive generations for the most effective walking behavior. The video below shows the products of some other evolution processes in breve:

Vladislav Delay -- Lumi

Good stuff. The video reminds me a bit of David ORielly's work, I like how the old mechanical quirks of early CG (flickering landscapes, stark textures, rigid movement, low polygon counts) are now being used aesthetically-- like impressionist painters intentionally using visible brush strokes, turning a flaw of their medium into a feature of their work.

Belousov-Zhabotinsky Reaction

And speaking of oscillations, here's a nice video of the Belousov-Zhabotinsky reaction in a petri dish:

(The video info for the above also has a nice description of waveforms in the brain which is worth reading.) You can see someone setting up the reaction (ie pouring some chemicals together and stirring, really) here.

The BZ reaction is an example of a chemical oscillator, a system which instead of arriving at a steady state transitions between two different chemical states (which two states have two different colors, whence the waves above). Boris Belousov discovered it in the 1950's when he happened to mix together potassium bromate, cerium(IV) sulfate, propanedioic acid and citric acid in dilute sulfuric acid (hell, why not?); he made two attempts to publish his findings, but was rejected from peer-reviewed journals because he couldn't explain why the oscillations occurred.

Rite of Spring

On a bit of a modernism kick; really such interesting stuff. Quoth Peter Childs (from wikipedia), "There were paradoxical if not opposed trends towards revolutionary and reactionary positions, fear of the new and delight at the disappearance of the old, nihilism and fanatical enthusiasm, creativity and despair." Or as Fitzgerald put it (at 23, goddamn I feel like an underachiever now), a generation "grown up to find all Gods dead, all wars fought, all faiths in man shaken."

So anyway, here's the Rite of Spring:

And here's a snip of a documentary on the music.

Lau Nau: Painovoimaa, valoa

I've got a couple posts brewing on augmented reality and architecture and modeling, but the days have been just packed lately. So here's this instead:

Basin Street Blues

Kid Koala's cover of Basin Street Blues, by way of Constant Siege. Really love the underwater feel of the animations, it goes well with the song.

Visualizing Music and Looking for Patterns

Found this and many other impressive videos on one Stephen Malinowski's YouTube channel. I really like the way the colored bar visualization separates out the different voices in a piece, especially the fugues.

The opening to Gödel, Escher, Bach has a fun discussion on the structure of the fugue-- the gist of it is that the composer develops the piece out of one short theme (a few measures of some simple melody), carried by a fixed number of voices. Starting with one voice expressing the theme, each additional voice chimes in repeating the theme until all are present. The theme is further explored and varied throughout the piece via transformations of the original melody: inverting, reversing, transposing, compressing. Soooo the video above is really cool, because the visualizations make it that much easier to pick out all the transformations that are taking place. Yay!

I wonder if you could make other visualization methods which help you pick out recurring themes in a piece, and are robust to transformations from the original theme (or measure distance from the original). It seems like a problem that crops up a lot, in problems from network analysis to predicting structural motifs in proteins. For instance, all integral membrane proteins will have a hydrophobic region which crosses the lipid bilayer-- this requires an extended sequence of hydrophobic amino acids, which will be reflected in the genetic code. There would be variation in sequence (not all membrane proteins would have the same arrangement of hydrophobic amino acids), but there might still be trends which might be picked up. Fourier/Laplace transforms can break a signal down into its periodic components; is there some way to transform a signal to visualize it in the space of its recurrent themes and their variations?

Machine with Wishbone

"Caught in a symbiotic relationship, both the wishbone and the machine are unable to manifest fully without the other. We drag our pasts with us and move according to unseen forces. More and more, we interface with the world through our mental and technological creations."

The Amen Break

Okay okay, I couldn't resist grabbing this as well-- again via the Worldwide Cultural Gonzo Squad, an oddly captivating video on the Amen Break, a six-second-long drum loop from the b-side of a 1969 single which was taken up by early sample-based music and is now the basis for entire musical subgenres, as well as every advertisement soundtrack ever. Also interesting for its discussion of copyright law, and the fact that it's narrated by a surprisingly realistic electronic voice.

A troubled relationship between a Cat and Mouse set in the distant Future. Winner of the Golden Bear for best short film at the 2009 Berlinale. (Click the link for full view.) His other stuff is pretty cool too, like When You're Smiling and the video he did for Venetian Snares.
