News may filter through Boing Boing, Slashdot, and Reddit – and certainly, this story already has. But oddly, I learned of this item when I happened to meet up with the blog item’s author in Somerville, Massachusetts. He has digital analysis he believes may prove that a track was recorded to a click track.

Paul Lamere is a developer at Echo Nest, a brainy think-tank of music geeks developing new ways of processing musical metadata in the cloud. Whereas services like Last.fm focus mainly on content and community, Echo Nest’s API wants to make the computers in the cloud smarter about how they listen to your music. We’ve had a look at their work twice before:

All Christmas Music, Boiled Down to Sixteen Droning Singles
Musical Brain API: An API for Music on the Web – And it Makes Pretty Pictures

The Remix API crunches data about rhythmic information at a number of levels. Since we first saw it, that API has led to an SDK (read: something you can program more directly), all assembled in Python. The Python-based SDK is now capable of creating the world’s most unlistenable mash-ups, among other things – some oddly compelling. On Friday, I got to listen to tunes with every other eighth note removed and Michael Jackson crossed with tunes – that is, until the programmers in the office started to complain because they were about to lose their mind. (Echo Nest uses a Sonos system to pipe music office-wide. I hope we can give you a preview of those clips soon.)

But perhaps the most interesting thing this team has done so far is Paul’s work on plotting rhythmic analysis. Plots of tempo deviation, measured in beat durations, yield two interesting revelations:

1. Much of the music you know has a lot of rhythmic variation. (Dizzy Miss Lizzie by the Beatles, anyone? No Ringo Starr jokes, please.)

2. A lot of the other music has disturbingly little rhythmic variation.

Delia Derbyshire, UK electronic composer extraordinaire and BBC Radiophonic Veteran, inspires depths of love and respect from us electronic muzos male and female that defy description. As Tara Busch from AnalogSuicide puts it, people aren’t just fans: they’re Delians. I think if you could see the image inside the heads of Delia fans at the mere mention of her name or the sound of a single sound effect, it’d probably look something like this slow-motion clip Tara posted to AnalogSuicide last fall:

(Well, the editor at the BBC working on the show obviously felt that way.)

I think people’s passions run this deep not simply out of a mad Delian crush, but also because of what she represents for the future of electronic music: Delia Derbyshire seemed to embrace sound with a relentless freshness and playfulness, the kind of spirit that could move forward the future of music in the same way she invigorated its past. And she came out of an entire scene of experimentation at the BBC and in the UK that could now spread virally online and in radiophonic workshops of independent musicians’ own creation.

Darren Landrum on Twitter is nice enough to send along two three newly-posted 1997 interviews with Delia on Radio Scotland. First part above; second part below. In YouTube bizarro fashion, they’re accompanied with strange sweeping slide shows, but Delia’s bubbling personality and insight shine through.

But perhaps you want to wear your Delian adoration on your sleeve, literally. Well, Analog Industries created a t-shirt this morning that, by the time Tom Whitwell (once and future Music thing creator) and myself Twittered and forum commenters posted, is now gone. Look out, Urban Outfitters.

Anyone want to try alternative Derbyshire couture? (Delia Derbyshirts?) Let us know; I have some screenprinting connections.

Part two of the interview:

I ask you: what is the foundation for rhythmic electronic music? I suggest that the humble step-sequencer is the backbone of many of today’s musical genres and memetic evolutions. To have electronic rhythm, you need to start with a clock and go from there, dividing it into fractions and multiples. Then start assigning sounds to those divisions and you’re pretty much there- techno is happening.

I’ve been working on prototyping a sequencer-synth and in doing research, I’ve come across numerous projects that tackle this idea with great enthusiasm. Because a sequencer can drive any type of electronics, projects tend to fall into two categories: audio, or visual. Additionally, I’m seeing two main drivers for the sequence itself: the nimble arduino, and the CMOS 4017 Decade counter IC. I’ll survey here some of the finished projects to give an idea of what’s possible. Come with me, won’t you, on an exploration of the world of DIY sequencers.
