Classic Lewy - Musical Composition on Evolution

On BBC2 last night - "Classic Goldie": The famous drum'n'bass populariser composes a piece for the 2009 Proms with full orchestra and choir. Themed on (his interpretation of) evolution; Starts with big bang, has tribal phases, spirituality heavy, etc. It's not that surprising that he manages to pull it off with some style, despite having no formal musical training and being initially unable to read notation; he has a professional composer as a personal assistant, an operator to solidify all the details onto computer and an entire orchestra of the most talented musical minds in the country to inspire and assist him.

+ Anyway, I couldn't help thinking about how I would go about creating a piece embodying evolution, starting from the *very beginning*, especially having recently been thinking about genes, memes, and temes.

It would be:

- A musicalisation (audio equivalent to visualisation) of an exponentially scaled (allegorical) history of the universe.

- It would have to show patterns (refrains), like sections of genetic code, cropping up, being copied/repeated (to other instruments), being slightly modified (some fail = stop, some continue & expand in length/complexity). The layers build up on top of one another, being played simultaneously, like a food web/musical ecology.

- A fairly simple concept that would take a musical genius (not me!) to make sound good, as well as being informative. The important bit would be the evolution of tunes ('melod-emes' as i call them), the linear history of time structure could be stripped away if desired.

+ Structure wise it would go somewhat like this:

- Start with a very, very rapidly crescendoing roar of every instrument played evenly (no distinguishable stick impacts or anything).
{inflation}

- The homogeneous roar slowly diminuendos, abruptly cutting out (but not *quite* all at once), leaving part of the percussion department still going.
{first atoms form, universe becomes transparent}

- Distinct beats can be discerned, but in no pattern and very rapid. Low, quiet tone from across the whole orchestral slides very slowly (so at first is not noticed; it has been there since transparency), then increasingly rapid, as it gets higher pitched, culminating in a blowtorch noise {stars ignite}. Perhaps a series of sliding notes from different parts of the orchestra (getting closer together in time) each resulting in a new layer of blowtorch noise.
{gravity takes hold; formation of galaxies, stars ignite}

- Difficult... but most of the layers of blowtorch noise would stop with a crash, one at a time.
{heavier elements synthesised & supernovas}

- Cyclical rhythms emerge in percussion, the more wild/haphazard/syncopated ones end abruptly end (in very loud bangs), leaving one steady beat (no syncopation).
{planetary systems resolve to stable orbits}

- Percussive bangs (not as loud as the planetary collisions, but the tail end of them), frequent but tailing off. Blowtorch still quiet in background. During the bigger gaps between bangs, bits of tune start to emerge, then are temporarily silenced by a bang (or 2), before resuming (the same, timid, simple tune (on one instrument)).
{Cometary impacts}

Difficult to represent asteroids bringing water to the earth's surface unless imitating or using recordings of ocean (wave) sounds, and splashes; don't want the piece to turn into a clip-art esq collection of sound effects!

- Several fairly discordant melod-emes (i.e. tune ideas/memes) might be heard around one section of the orchestra (at random timings, on different instruments of e.g. the string section) then one catchy melodic tune appears and is repeated immediately across that section (so becoming louder, more distinguishable), then split octaves (for cello vs viola), harmonised too perhaps.
{organic chemistry leads to self replicating molecules & genes}

- The above process is repeated for each new section of instruments {species of animal}. In principle they should start with the same tune as the section before, then embellish and add to it. The effect should be a little like singing "London's Burning" in rounds, but much more complicated and with intermediate steps (which are free to clash a little with the existing notes for a while).
{building of ecosystems}

The first melod-eme could start on double-base (e.g. 3-4-3-1-2-4-repeat; bass riff notes), repeating every bar. Then cello (or whatever) joins in the same tune for a bar before adding additional notes in-between on the next repetition. (now i'm just thinking of a jazz number with each instrument coming in, in turn until the star trumpet/clarinet player really takes the tune away into ad-lib craziness. Not quite what i was aiming for, but a good alternative.)

Harmonies/chords on the same (set of) instrument(s) could represent {multicellular organisms}, but perhaps that's a bit of a stretch of interpretation.

- After the bunches of tunes have reached crescendo for a little while (and been dominated by low brass instruments {dinosaurs}), another cometary crash silences the more complicated (recently added) half of instruments/tunes. A new set of melod-emes emerges (more rapidly this
time) along a distinctly different feel of refrain.
{mass extinction > beginning of mammals}

- Need a particularly catchy tune (melod-eme) for humans, medium long, and perhaps on an instrument/played in a way that definitely hasn't been heard yet (in the piece).
{humans}

- Much of the detail of different/convoluted tunes across different instruments can be stripped away now, being replaced by/turning into harmonies of that fit with the dominant {human} tune.
{Agriculture/animal domestication, massive extinction}

- Choir would come in at this point, no words as such (obviously would spoil the music as an analogy, rather than dialogue), should give a ominous effect. Drops away a little as the next feature comes in fully.
{religion}

- Synth/electric instruments (perhaps traditional rock band set) kick in with their own (complimentary, but more jagged/cutting/staccato) tunes.
{technology memes}

This has now become distinctly rock music (with orchestral backing). 2 drum fills could be inserted for the world wars.

- Volume is now becoming unbearably loud, with lots of extra detail stemming from and fitted around the main human refrain (that has transferred dominance to the electric instruments (perhaps lead by lead-guitar)). Extra layers of guitar and funky beats joining in.
{20th century => Current => G.N.R. revolutions}

- Perhaps a very rapid electronic tuned synth whizzing around everywhere like at insanely fast auto (tone) dialler/modem.
{Internet through to AI}

All tunes/rhythms/patterns that have been heard throughout the piece join back in for a brief, orgasmic climax (fairly strong choir/religious sound permitted, but not dominant).
{Singularity}

- Ending is a paradox, because the Singularity (and evolution itself IMHO) is all about eternal progress, without end, in subjective time. I think, if the roar of orgasmic detail where to inverse rapid-fade (like a backwards explosion/cymbal crash) to deliberately mirror the very beginning (of the piece), that would be as good as could be done:

That way it shows the perspective from real time (if we have Tiplerian Singularity in a closed universe). It also rounds off the whole of existence; there is nothing external to the piece, no before or after movements; all of the meaning/purpose/detail is contained within. And the manically chaotic ending roar is shown to be the polar opposite of the homogeneous beginning roar (having experienced all the details being built up), despite it sounding indistinguishable on first impressions.
[Above: a little composition by me for this article]

+ In principle the music should build up in layers, each on top of the next; the blow torch of the suns, rhythm of the orbits, basic repetitive first tunes {of the micro-organisms}, should continue in the background behind the detail of everything that comes thereafter (like the foundations of an upside-down pyramid). In practice they will definitely need to be gradually faded down to allow the next layer to be properly heard, and probably faded out altogether (until the very end).

+ Writing the combined, interlocking ecosystem of tunes for the end of the piece will be almost all of the work. From there, one can work backwards, taking out notes and simplifying rhythms, making deviations for failed attempts {at species} and writing the alternative {dinosaurs} themed tuned section.

- An existing piece of music (with sufficient depth of layers) could be deconstructed in a similar manner, for this purpose.

- Fragments of Well known tunes could be incorporated into the piece for an ultimate mash-up. However, this would distract too much from the overall meaning of the piece (if that was what was considered important); listeners would start playing name the song.

- The deconstruction could be done automatically with an algorithm/AI. Or built up dynamically using genuine evolutionary algorithms, with a fitness function that rates the resulting listenability or the music (the difficult bit; getting an AI to appreciate music effectively).

+ It might be possible to get the bare bones of this idea done with just jazz band (or even rock band) instruments... That should certainly keep it from getting unhearably complex. In the mid section that would be desirable, but at the end that's the exact effect aimed for. Would have to increase the tempo instead to achieve the same effect.

+ I just realised that a visualisation made to fit with my hypothetical composition would be somewhat like a scientifically rigorous version of the "Big Bang Theory" introduction... They'd do well to replace their original (annoying as hell) theme tune with a (highly condensed) version of my composition!

The Audacity of Spotify

In response to a Facebook post: I think Spotify is a pretty impressive offering. I've been wondering for a while why no one had made something like this. Finally 'they' have. Think I'll be sticking to using my enormous mp3 collection most of the time still.

+ What's hot:
  • Very immediate playback (far quicker than torrenting mp3s)
  • Full quality sound (as good as 160kbit/s mp3 imho).
  • Good buffering (track will finish playing even if connection is entirely lost).
  • Plenty of information on albums and artists (like a sleek version of AMG/IMDB); intuitive and highly functional interface.
  • Good as a music discovery tool (with links to buying too).

+ What's not so good:
  • It lacks similar artist links or a recommended artists/customised radio channel functionality like Last.fm or Pandora.... Oh, hang on! I just found them! But the “Artist Radio” doesn't play similar songs, it just links to the other artists. Wait, it does that too! Wow.
  • The search function is simplistic, requiring exact spelling.
  • You never own your music, but that's all right because it never tries to pretend that u do (unlike DRM locked downloads).
  • The ads are unavoidable on the free version; it knows if u mute your sound or turn it right down, or if u move the banner ad off the screen it moves to a different part of the window, which is fair enough and besides, the adverts are mostly targeted and the audible ads are quite brief (but fairly frequent).
  • No internet connection means no music, even though it stores content locally, presumably because it can't show adverts (does the pro version work fully off-line?).
  • No track numbers shown in play list; clearly it's intended for use as an iTunes substitute, used mainly by people who want to cherry pick favourite tracks rather than listening to entire albums.
  • Some big name material is unavailable, e.g. no “In Rainbows” as yet (though the ad banners seem to suggest it's coming to spotify premium). But there is a lot of my slightly obscure artists on there and they are still in Beta so I'll give them some leeway.

+ The artist biography information is the same exactly the same blurb that can be found on any site pertaining to music, so I wonder where it originally comes from, and whether Spotify pay for it? The only place I found it attributed to a specific person was “All Music Guide”.

+ I'm curious what licensing arrangements they have, that they can allow people to listen to an unlimited amount of music for only £10/month... could it be too good to last? It must certainly be an enormous headache for them to negotiate with the different labels with content only being made available in certain countries and being able to be withdrawn at any time.

+ It would be cool for small artists if it included geographical information too: local live performances. This could form the perfect basis for a micro-royalties system (paying money to artists only for songs that were actually listened to), perhaps enabling tiny artists to bypass record labels. However, if they only get as much per play as the biggest artists, they're probably going to get very little money. I think there should be a principle of diminishing returns applied (e.g. An artist with 1 million plays only gets twice as much money as an artist with 100k plays, etc). So there's still incentive to create the best music, and one could certainly make a living from it, but at the same time many more artists could also afford to go full time, leading to an explosion in the number of creative minds at work in the 'industry'.

+ Why didn't (doesn't) Kindle take this approach too? (or at least have it as an optional package): unlimited book access for a flat monthly cost? I expect it's because publishers (or publishing laws) are *even less* reasonable than record companies.

+ If Spotify can be kept alive with it's content collection continuing to grow, and later versions incorporate fully featured music discovery, it could become the perfect music tool for desktop PCs.

+ As to reaching mobile platforms, that's a different matter. In principle they could start giving away (high speed) wireless handsets with a minimum Spotify subscription: a flat rate Kindle for music. Of course, mobile operators/makers cold take the initiative too and bundle Spotify with contracts. Given Apple's record so far, with 3rd party iStore apps, this does not yet look likely.

[Imported from "LewyLife"] A 3rd blog for the personal and mundane:

Hey, so I've been feeling particularly tired and rubbish of late, but never mind. I've still been able to finish reading Accelerando (by Charles Stross - basically a dramatization of "The Singularity is Near" by Ray Kurzweil) and check out some new software/services:

Since previously trusty Firefox went to pieces on my 64bit computer for no apparent reason, I've been needing an alternative. Eventually i got around to trying Opera (which I'm using right now). It has tabbed browsing and some useful features Firefox doesn't have, so I recommend it.

This groovy picture by Eboy inspired me to check out a few other things:

Last.fm - a custom internet radio player, equivalent to Pandora, arguably better.

Well, err, actually that's all the new stuff I'll be using from there for a bit, but i did also just get on Facebook which had been coming for a while. Well… gotta try and stay in touch with the youth, you know, even if i am just an old fart at heart!

2023-11-29 Addendum: I've imported the few posts from my old LewyLife blog to this less defunct blog, and deleted that to tidy up. Images missing that were presumably embedded via URL links only.
