Anyone seen "AI"?

First I'd like you to listen to the music on this. It's two short excerpts from a coupla classical pieces.

What did you think? Ignore the name "David Cope" over there. Who do you think wrote it?

"Emily Howell" is the project name given to AI-composer program. It's predecessor was "EMMY" (Experiments on Musical Intelligence), and both were created by composer, scientist, and UC Santa Cruz professor emeritus of music, David Cope. Sadly, I couldn't find any other clips of its compositions, but I've heard some from "EMI" before, and they were pretty good.

I put this here not just because it's pretty damn amazing that a machine can write music (pretty good music, actually), but also to talk about people's response about it.

http://www.miller-mccune.com/culture-society/triumph-of-the-cyborg-composer-8507/

Here's the main article; it's a great one but also pretty long, so I'll just copypaste some paragraphs of interest.


Some background on Cope:
"Cope sailed through music schooling at Arizona State University and the University of Southern California, and by the mid-1970s, he had settled into a tenured position at Miami University of Ohio’s prestigious music department. His compositions were performed inCarnegie Hall and The Kennedy Center for the Performing Arts, and internationally from Lima, Peru, to Bialystok, Poland."


First reactions to EMMY (or EMI):

"Cope attracted praise from musicians and computer scientists, but his creation raised troubling questions: If a machine could write a Mozart sonata every bit as good as the originals, then what was so special about Mozart? And was there really any soul behind the great works, or were Beethoven and his ilk just clever mathematical manipulators of notes?

Cope’s answers — not much, and yes — made some people very angry. He was so often criticized for these views that colleagues nicknamed him “The Tin Man,” after the Wizard of Oz character without a heart. For a time, such condemnation fueled his creativity, but eventually, after years of hemming and hawing, Cope dragged Emmy into the trash folder.


Something about music that's composed algorithmically, as opposed to inspirationally:
"During the 18th century, Joseph Haydn and others created scores for a musical dice game called Musikalisches Würfelspiel, in which players rolled dice to determine which of 272 measures of music would be played in a certain order. More recently, 1950s-era University of Illinois researchers Lejaren Hiller and Leonard Isaacson programmed stylistic parameters into the Illiac computer to create the Illiac Suite, and Greek composer Iannis Xenakis used probability equations. Much of modern popular music is a sort of algorithm, with improvisation (think guitar solos) over the constraints of simple, prescribed chord structures."


Early response:
"[Cope asked] which pieces were real Bach and which were Emmy-written Bach, most people couldn’t tell the difference. Many were angry; few understood the point of the exercise."


More recent response, something that pisses me off a bit:

"At one Santa Cruz concert, the program notes neglected to mention that Emily Howell wasn’t a human being, and a chemistry professor and music aficionado in the audience described the performance of a Howell composition as one of the most moving experiences of his musical life. Six months later, when the same professor attended a lecture of Cope’s on Emily Howell and heard the same concert played from a recording, Cope remembers him saying, “You know, that’s pretty music, but I could tell absolutely, immediately that it was computer-composed. There’s no heart or soul or depth to the piece.”

That sentiment — present in many recent articles, blog posts and comments about Emily Howell — frustrates Cope. “Most of what I’ve heard [and read] is the same old crap,” he complains. “It’s all about machines versus humans, and ‘aren’t you taking away the last little thing we have left that we can call unique to human beings — creativity?’ I just find this so laborious and uncreative.” "

Frustrating.

Now I'm big on classical, and it's incredibly hard to imagine a machine spitting out works of Chopin, Liszt, Rachmaninoff, etc. I'm honestly not too sure of what I feel about all this AI jazz (heh), but the closed-mindedness that some people show is just infuriating.


Here's some more philo for you to munch on:

"In his view, all music — and, really, any creative pursuit — is largely based on previously created works. Call it standing on the shoulders of giants; call it plagiarism. Everything we create is just a product of recombination.

In Cope’s fascinating hovel of a home office on a Wednesday afternoon, I ask him how exactly he knows that’s true. Just because he built a program that can write music using his model, how can he be so certain that that’s the way man creates?

Cope offers a simple thought experiment: Put aside the idea that humans are spiritually and creatively endowed, because we’ll probably never fully be able to understand that. Just look at the zillions of pieces of music out there.

“Where are they going to come up with sounds that they themselves create without hearing them first?” he asks. “If they’re hearing them for the first time, what’s the author of them? Is it birds, is it airplane sounds?”

Of course, some composers probably have taken dictation from birds. Yet the most likely explanation, Cope believes, is that music comes from other works composers have heard, which they slice and dice subconsciously and piece together in novel ways. How else could a style like classical music last over three or four centuries?

To prove his point, Cope has even reverse-engineered works by famous composers, tracing the tropes, phrases and ideas back to compositions by their forebears.

“Nobody’s original,” Cope says. “We are what we eat, and in music, we are what we hear. What we do is look through history and listen to music. Everybody copies from everybody. The skill is in how large a fragment you choose to copy and how elegantly you can put them together.

I've always had a nagging thought like this floating around somewhere. Books you read influence your writing style; the people you're with influence how you act and speak. How is music any different? I'll admit it, my crappy improv often takes on the tone and style of music I listen to.

Hmm. Or were the greats really just plain brilliant? Natural-born, completely inherent talent? Why is it that the great composers were alive around the same time? Did they not influence and help each other to improve? I don't know, but it's worth thinking about.



Finally, here's the funniest Hitz.fm "Gotcha!" ever lol:

Winter 2009 - Switzerland: Interlaken, Part 2

Jan 9th

So we had two options: spend another full day wandering around Interlaken, or do something
that's fun but expensive. There were a buncha things to choose from, canyon bungy-jumping, skiing, snowboarding, etc.

One particularly interesting one was an 8-hour trip up and down Jungfrau, known as the peak of all Europe. Here's the description from Frommers:
_________

"With luck, you'll get good weather for your day trip; you should always consult the tourist office in Interlaken before boarding the train. The trip is comfortable, safe, and packed with adventure. First you'll take the Wengernalp railway (WAB), a rack railway that opened in 1893. It will take you to Lauterbrunnen, at 784m (2,572 ft.), where you'll change to a train heading for the Kleine Scheidegg station, at 2,029m (6,655 ft.) -- welcome to avalanche country. The view includes the Mönch, the Eiger Wall, and the Jungfrau, which was named for the white-clad Augustinian nuns of medieval Interlaken (Jungfrau means "virgin").


At Kleine Scheidegg you'll change to the highest rack railway in Europe, the Jungfraubahn. You have 9.6km (6 miles) to go; 6.4km (4 miles) of that will be spent in a tunnel carved into the mountain. You'll stop briefly twice, at Eigerwand and Eismeer, where you can view the sea of ice from windows in the rock (the Eigerwand is at 2,830m/9,282 ft. and Eismeer is at 3,110m/10,201 ft.). When the train emerges from the tunnel, the daylight is momentarily blinding, so bring a pair of sunglasses to help your eyes adjust. Notorious among mountain climbers, the Eigernordwand (or "north wall") is incredibly steep.


Once at the Jungfraujoch terminus, you may feel a little giddy until you get used to the air. There's much to do in this eerie world high up Jungfrau, but take it slow -- your body's metabolism will be affected and you may tire quickly.


Behind the post office is an elevator that will take you to a corridor leading to the famed Eispalast (Ice Palace). Here you'll be walking inside "eternal ice" in caverns hewn out of the slowest-moving section of the glacier. Cut 19m (62 ft.) below the glacier's surface, these caverns were begun in 1934 by a Swiss guide and subsequently enlarged and embellished with additional sculptures by others. Everything in here is made of ice, including full-size replicas of vintage automobiles and local chaplains.


After returning to the station, you can take the Sphinx Tunnel to another elevator. This one takes you up 107m (351 ft.) to an observation deck called the Sphinx Terraces, overlooking the saddle between the Mönch and Jungfrau peaks. You can also see the Aletsch Glacier, a 23km (14-mile) river of ice -- the longest in Europe. The snow melts into Lake Geneva and eventually flows into the Mediterranean."


_________
Major downside: It was about 150USD each wtf?! Furthermore, the weather was pretty bad, meaning there was a high chance we wouldn't have been able to see much.

In the end we settled for a ski trip up the mountains (canyon bungy was about 150 too =="). Equipment rental, a lift pass, and a train ticket cost us about 140usd.

Got up in the morning and took a train up the mountain. We met a guy from UC Berkeley at the bus stop; he saw my Cornell hoodie and started talking to us :D

Here's a trail map that covers most of the ski/snowboarding area:
I cannot stress how damn big this area is. We took a train ride from "Interlaken West" up to Grund, which took about 20 minutes. Here's a map of the Grindelwald area:
From Grund, we took another train up to Kleine Scheidegg. Berkeley guy was on his 3rd or 4th ski day here, and said something like "Oh yeah, just get off at Kleine Scheidegg, ski back down to Grund, and take the train back up!" Sounds damn easy hor. lol -_-

Once in the while, the train would pass through a tunnel-thing build around the mountain. The view would change pretty dramatically after each tunnel; pretty damn breathtaking.
Lower area.
That blanket of thing in the middle? Clouds, wtf.
I don't think any camera or photographer can do justice to the view that met us there (no photos I've found are anywhere on the same level as the real-life view). You just can't capture the magnitude of these mountains on a tiny photograph. When we got off the train at Kleine Scheidegg, it was like... whoa, I've died and gone somewhere else.

White in every direction with a view of mountains down below that seemed to stretch out to infinity; yet there were still even higher peaks that loomed above us. Massive rocky things covered with snow, with some humble train tracks circling the mountain. "Majestic" and "Breathtaking" would be the understatements of the year. One of the most epic things I've ever seen. Damn, we're tiny.

Okay, back to Earth. Here's Jian.
and a Heineken tepee in the background lol.
Another shot of Kleine Scheidegg. See that semicircular thing near the middle-right of the pic? That's the beginner trail that we'd eventually take.
Don't drink and ski lol.

I'd been skiing a total of three times. Once when I was eight, on a holiday at my uncle's house (he lived in Zurich); another time, for about 45 minutes in Korea with my relatives sometime in high school; and the last time in 2006, on my exchange trip to Japan. So I was still considered pretty noob lah lol.
Another shot of lifts that go above Kleine Scheidegg.

Helped Jian find his bearings a bit on a bunny slope somewhere, while I rediscovered mine.
Here he is on the "bunny slope".
After that I went ahead and tried the "Beginner slope". Beginner, my ass! wtf lol, it's about the same level as the "Intermediate" slopes at the mountain behind Cornell. Yes, we have our own fuc*ing mountain to ski on. I'm taking snowboarding lessons now (and they're going reaaallly well :D), so I spend every saturday boarding down Greek Peak. Awesooome.

I'm a strong advocate of "drowning man learns to swim"; do something way above your current level and you'll adapt to it way faster than if you learn from bottom-up. Fall lots, and your body will learn how to avoid it. Muscle memory! I'm a pretty quick learner when it comes to stuff like this (no shame lol :D), plus I'd taken rollerblading and ice-skating lessons as a kid.. so all that really helped me find my balance and stuff.

The route down was AMAZING. The thoughts "Damn, I'm skiing down the Swiss Alps!" coupled with the fact that, you know, I was skiing down the damn Swiss Alps, made it even more so. Honest-to-goodness it was one of the most awesome things I'd done in my life. The thing about skiing is that you can control pretty much everything you do; it's up to you to decide whether to (try to) speed all the way down or take it slow, to ski with style or to just barely make it down.
Got to the "bottom" of the beginner trail. Was only like 1/4 the distance of the ski-down-to-the-train-station route that Berkeley guy had suggested. Took about 15-20 mins the first time?
Taking the ski lift back up.
One of the many mountains in the area.

Only after a while did we discover a "beginner's area"; a roped-off area for beginners to learn.
Met an Irish couple there, and they offered to take a photo cause they thought the snow on my hair was awesome, which it was. We didn't rent goggles (kiamsiap), and I didn't have any headgear, so by the end of the day my head was literally snow-white.

We spent about half an hour there, then I dragged Jian to take the "beginner slope" with me.

Falling down a hill hurts like sin. Falling down a snowy slope, on the other hand, is actually pretty fun. You can tumble and flip down fifteen metres on a wipeout and not feel a thing. So yeah we had an awesome time there. When we got thirsty, we just ate the snow lol. I mean, you freaking PAY for water from the alps right? Free of charge here. Sweet and refreshing, nom nom nom. Visibility was pretty low; snowstorms on that day ):
Could barely see the trail lol.
Here's Jian after a wipeout. Whee.

We did the slope once more after that. Jian had a couple of pretty bad wipeouts and got snow in his jacket, so you can be sure he was pretty damn cranky for the trip down lol. And hungry. Food up there was too expensive ahaha.
At the lift station, before going back up! Nice lift operator helped us take a coupla photos.

Once we got back to the top, Jian went to get food and shelter while I went down one last time. Zero falls this time! Plus, visibility was REALLY FREAKING BAD. Literally couldn't see more than 10m ahead -_- omg. Had I not done the route three times, I probably would've gotten lost somewhere. This time it only took 5-7 minutes going down.

Last pic of the day: Trail map at Kleine Scheidegg.
Note the "Avalanche Alert".

And that's it for Interlaken! We went back to our hostel, made some food and slept. Jian went back to Winchester the next day, and I continued on my journey to Munich, Germany. Alone.

Not Dead!

Will be updating pretty soon. Cornell's been a real killer these few weeks.
