Music ... Science ...

Just a quick thought tonight on chaos theory and fractals . . . and music. Chaos theory, in the strict mathematical sense, is based on the notion that many natural processes and social networks operate in a fashion in which their future state, e.g. how things will be tomorrow or next year, is largely determined by their present state.

However, this does not mean that things stay the same. Systems such as the weather or the stock market become chaotic because the relationship between present and future states is “non-linear”, i.e. based on mathematical functions that in-and-of themselves twist around. There is no straight-line proportionality. Things jump around a lot; but in the long run, there are patterns that can be found within that jumping around. That’s the crux of chaos theory. Chaos theory does not deny that future states are also heavily influenced by “exogenous shocks”, i.e. “black swans”, things that aren’t part of the pattern nor within the “state space” region where the system usually noodles around.

Fractals are in some ways much like chaos and in other ways different. Fractals focus on repeating patterns that may not be obvious at first when beholding  »  continue reading …

Brain / Mind ... Music ... Science ...

A few days after writing my Sad Song blog, about how a tune by The Cars pulled me out of the dumps on a very trying and frustrating day, I read an interview in the May Scientific American with a hearing specialist and surgeon who is performing neuroscience research on musical creativity. I.e., what goes on in the brain when a songwriter sits at a piano sit at a piano searching for a pleasing series of notes, or when a bunch of performers improvise and exchange riffs. The pace may be different in these two situations, but the overall process of creativity is about the same. But just what is that process all about?

The interviewee, Dr. Charles Limb, mostly said that more research is needed before anything definitive can be said. So the article is more about investigating an unanswered question than about explaining a new scientific discovery. Another interesting question that Dr. Limb asked towards the end of the article – and again left unanswered – is “why do we love sad music? Why does it make us feel better and not worse?” Hmmmm, that’s a darn good and interesting question, especially given how I resolved my Friday the 13th blues earlier this month. We don’t seek out other sad and depressed people when we’re feeling down; that just makes us feel worse (most of us, anyway). But we certainly do love our sad songs, and maybe movies and paintings too. What’s the difference?

If a scientist like Dr. Limb can’t give a good answer, I certainly can’t. But heck, that never stopped me before.  »  continue reading …

Music ... Personal Reflections ...

Yesterday I had the Friday the Thirteenth blues. Nothing all that bad, really. I didn’t see the doctor for test results, I didn’t lose $10,000, I didn’t lose my job (I hope), I didn’t get a thick envelope in the mail from a lawyer, and no one I knew got hurt. So yeah, I should count my blessings. But it was still a frustrating day. As the morning dragged on at work, a bunch of things that should have been settled days, weeks or months ago came back unsettled. The trend continued throughout the afternoon. More e-mails, more phone calls, more visits from co-workers. I tried to settle what I could, but the wave was too big; I left around 5 with a huge to-do list for next week. And in the midst of all this, it occurred to me that I’ll never have a romantic relationship again, as the fires and passions that ruled my youth have cooled far too much. I could never go thru the craziness of it all again.

I felt a bit better in the evening, sitting with my brother in a local bar-restaurant with a Guinness Draft under my chin. But then he got into the weekly review of the situation with his girlfriend, and it sounded pretty much like the report from last week; and the week before that, and the month before that, and . . . Well, let’s just say that they are caught in a loop . . . can’t live with you and can’t live without you. (Hmmm, maybe it ain’t so bad about my own fires having cooled . . .)

OK, it’s a little more complex than that – i.e., can’t live with your kids, whom you can’t live without, and who can’t seem to live without you, despite being in their mid-20s. I asked the usual questions:  »  continue reading …

Music ... Personal Reflections ...

I recently met up with a guy from college who I hadn’t seen since the late 70s. His name is Al Lacki (hi Al!) and he reached out to me after accidentally coming across this web site! We had a good chat over a few beers, with lots of reminiscing, catching up, and pondering the world in a way that only engineering school graduates can ponder it. He’s got a great web site dedicated to Corvairs and other rear engine cars. If you’re into Corvairs it’s definitely a must-see site. And even if you’re not, it’s worth a visit.

In other recent doings, I got hooked on a band that started out over 20 years ago, not long after Al and I had last seen each other. They’re called Sawyer Brown, and they’re known as a modern country and western act. I was never big on country and western; it just gets too twangy and weepy and harmonic for me (although it does bring back memories of younger days when I used to cruise the hinterlands of Pennsylvania and Ohio and Maryland and Virginia on photo expeditions). Sawyer Brown is still pretty twangy and weepy and harmonic. But they mix a lot of rock and roll into their music, so it isn’t so hard for an old time rocker like me to relate to it.

I recently picked up their album “The Hits – Live”, and I have to say that it’s an easy album to listen to, with elements of evocative story-telling, good-time foot stompin, honest sentimentality, and sly humor (something that rock and roll doesn’t even try to do). The song that best combines humor and country-style narrative is called “800 Pound Jesus”. It’s hard to say if the song is a parody of the typical country faith song, or whether it still has a theological agenda (or maybe both). But it does have a catchy refrain, one that you can sing while walking in from the parking lot in the morning. The basic premise of the song is that a guy stops at a yard sale and buys an eight-foot high concrete statue of Jesus. The refrain obviously claims that this statue weighed 800 pounds.

Having been trained as an engineer (in the same class with Al), I decided to investigate the weight claim; would an eight-foot tall human statue in concrete really weigh that much? OK, first question: what is the cubic volume of a human body? A science web site suggested that the volume of our bodies depends mostly upon our weight, and suggested using a conversion factor of 1 cubic centimeter per gram. Let’s assume that Jesus was relatively tall and thin; I’ll guess that he weighed around 140 pounds, since he did a lot of walking and ate mostly fish and figs and wheat berries. Remember, there were no Big Macs or three-meat pizzas back then. There are 453 grams per pound, so we shall re-state Jesus’ weight in metric, as 63,420 grams. Then using the cubic centimeter-to-grams conversion factor of 1, we can say that Jesus’ body filled about 63,420 cubic centimeters of space.

Next, I’ll guess that Jesus was about 5 feet, 11 inches tall; an average height today, but back in the old days of malnutrition, relatively tall. No one in the New Testament bothered to describe what Jesus looked like; he could have been a shrimp. But the Gospels do indicate that Jesus had a very charismatic personality, and guys like that are usually pretty tall. So, I’ll go with 5 feet, 11 inches, which can also be stated as 5.9 feet.

Sawyer Brown points out that the statue in question was 8 feet tall. We will assume that the statue is correctly proportioned for a tall, thin human (as most Jesus statues are); so, in order to estimate its volume from the 63,420 cubic centimeters for the actual Jesus, we need to scale up each dimension (depth, height and width) by a factor of 8 / 5.9. The volume increase factor is thus (8/5.9) x (8/5.9) x (8/5.9), which is about 2.493. So we multiply 63,420 by 2.493, and get 158,106 cubic centimeters for the concrete Jesus. That’s a lot of concrete. Another web site estimates that dry concrete weighs at least 2.3 grams per cubic centimeter. So, the concrete Jesus must weigh around 363,643 grams, which is 363.6 kilograms. Each kilogram equals about 2.2 pounds. Multiply 363.6 by 2.2, and we get . . . 800 pounds !!!!! (Actually, it could be a bit more, since I didn’t account for the added volume from the statue’s robes.)

(The question remains, however, how the guy in the song got this statue home; even if he had a heavy duty pickup truck, as a lot of country-western fans do, he would still need an industrial hoist to load and unload the statue.)

I hope that Al Lacki is proud of me for quantitatively investigating the weight issue! But despite our marvelous mathematical intellects, Al and I must bow down before the greater power involved here. As the refrain to “800 Pound Jesus” goes, “he’s a bigger man than you or me.”     :^)

Music ...

Way back in the 1970s when I was in college, a hard-playing band hit the rock scene. They were called KISS. They were arguably the last of the four-man super-groups patterned after the Beatles, where each member was considered an equal. Since the 1980s, it seems as though most rock bands revolve around one guy, e.g. Steven Tyler and Aerosmith, Kurt Kobain and Nirvana, Eddie Vetter and Pearl Jam, Bono and U2, Ed Roland and Collective Soul, Chad Kroeger and Nickelback, etc. KISS was the last band that I memorized the names of each member: Gene Simmons, Paul Stanley, Ace Frehley and Peter Criss. (How many people memorized all the members of The Doors?). By the late 70’s, KISS music was a given; tune in any rock station and you were going to hear some KISS.

Actually, I wasn’t a big Kiss fan. I did take a liking to Detroit Rock City, especially before they toned it down by removing the big car crash at the end. But otherwise, Kiss’s music was OK but nothing special. I never did see them in concert; just wasn’t impressed by the crazy costumes, the bizarre guitars, and the makeup. I never bought any of their records either (what for? they were always on the radio).

And now here it is, 30+ years since Kiss hit the big time. Like me, the band members are getting old. Their voices aren’t quite what they used to be, and their bodies probably aren’t up to the wild theatrics that thrilled their fans, not to mention the sex and drugs that went together with rock stardom. I read the other day that drummer Peter Criss has developed carpal tunnel syndrome. But back in the gravy days, Kiss and their fans never imagined that old age would someday start catching up with them — no young person ever does.

Nonetheless, Kiss did muster enough energy for a 30th anniversary concert back in 2003. They did what some other bands had tried in the late 90s and early 00s — they performed live with a professional orchestra behind them (the Melbourne Symphony Orchestra, in Melbourne, Australia). And they put out a CD and DVD from that concert, called Kiss Symphony, Alive 4. Almost three years after that concert event, in the sunset of their fame, I finally gave in to the Kiss phenomenon by buying a copy of the Alive 4 CD.

At my age, it’s hard to fall in love with a song. When I was young, it would happen every month or so. But now, almost nothing new catches my ear. However, when I heard the symphonic rendition of “Love Gun” on the radio last week, with violins and horns fighting for attention against Kiss’s driving guitars and pounding drums; with the disciplined power of the orchestra conductor competing against the raw urgency of Kiss’s sexual lyrics, I had to smile. I knew that this was music I had to hear. A quick tour of Ebay showed that Alive 4 was available for $10 (with shipping). So I took the plunge.

The nice thing about Alive 4 versus the other symphonic concert ventures that various bands such as Deep Purple, Metallica and the Scorpions have made in recent years is the incredible tension between Kiss’s “loud and wild” style and the orchestra’s complex discipline. There are over 100 reviews of the album on Amazon, and most of them either love it or hate it. I personally enjoy the contradictions, the yin and yang of the Kiss / Melborne Symphony Orchestra interaction on Alive 4. It’s just too bad that Kiss waited so long to try this.

It’s also a shame that this approach is mostly a novelty. To me, symphony music lacks spontaneity and liveliness, and yet rock music lacks the intelligent design and wonderful range of instrumental sounds that are blended together most every night by concert orchestras. If you could put the two styles together somehow, you would have a sound experience that approaches the full range of human experience. On Alive 4, Kiss and the Melbourne Symphony Orchestra came pretty close at times.

Not that the whole album is perfect. Far from it. The first six songs in fact are by Kiss alone. And they are good songs, but you can sense that this is an old rock band that hadn’t been working together much lately. There are some obvious off-notes and missed beats (but not serious enough to stop the flow of energy that even a middle-aged Kiss brings to their music). Five songs then follow where Kiss is backed up by an “ensemble”, a lite version of the orchestra. The first tune in this lineup is probably the worst of them all; it’s the power ballad “Beth” by drummer Peter Criss. Despite his hand problems, Criss can still keep a beat; but his voice is not a young, supple voice anymore, which is what “Beth” calls for. No mind, though. The next four numbers are melodic harmonizers (Forever, Goin’ Blind, Sure Know Something, Shandi), which are accented nicely by the ensemble strings.

Then comes Act Three, the main event. Kiss and the full symphony orchestra cut their way through ten solid rockers. They start out slow with Detroit Rock City, where the orchestra seems to put a drag on the wild energy that drives the tune. But after a few measures, Kiss brings it up to speed, and the oboes and flutes and cellos soon contribute to the momentum. At many points, the screaming lyrics and wailing guitar-work drown out the orchestra; but conductor David Campbell always seems to bring it up for air and recaptures the stage with a dramatic violin or horn movement. When it all finally wraps up with the Kiss National Anthem (I Wanna Rock and Roll All Night), you wish it could last longer. You wish there were other albums like this, maybe done with younger guys still in their prime. But no; it’s back down to reality, back to the modern moodiness of Nickelback and Staind and Godsmack (oh, and let’s not even get into trance and hip-hop stuff). The younger folk just don’t share this vision. Once again, I got a quick taste of the world as I would imagine it, only to have it pulled away in favor of the world such as it is. That’s pretty much been the story of my life.

But I shouldn’t complain too much, as one day life will be over (I hope that’s still a ways in the future yet). And maybe there’s an afterlife. And maybe Saint Peter will be there to greet us at the gate to eternity. But if instead, it were Gene and Paul and Peter and Ace (or his replacement on Alive 4,Tommy Thayer) who came out, with full makeup, and they shouted in unison “THE PARTY’S JUST BEGUN, WE’LL LET YOU IN” . . . . well, I’d be a bit uncertain as to whether it was heaven or hell. (If the orchestra were also there, I’d be a little more at ease about it all.)

But either way — it would probably turn out to be all right.

Current Affairs ... Foreign Relations/World Affairs ... Music ...

It’s always great news when an uprising for freedom starts in some foreign land where tyranny and oppression has long been the norm. Remember Tienanmen Square in China in 1989. But it’s even better when an uprising actually gets somewhere. Like in the Ukraine. It looks as though the Orange Revolution has succeeded – opposition leader Viktor Yushchenko has been declared the winner in the new Presidential election, which was called after the original vote was declared fraudulent and irregular. (Now why couldn’t we do that in the US back in 2000?). Viktor Yanukovich, The pro-Russian establishment guy, is still complaining but the election observers seem to be in agreement that Yushchenko won fair and square. Sorry, Mister Putin, but your next door neighbors ain’t gonna just snooze their way through your efforts to re-establish the Soviet Union, even if your own people will.

You know who is snoozing through this one, though? Weird Al Yankovic, that’s who. Yea, Weird Al, the pop singer and comedy stylist who got some attention back in the 80’s with his takeoff on Queen’s “Another One Bites The Dust”. Of course, under Weird Al the refrain became “Another One Rides The Bus”, a tale of unwashed homeless people getting on a public bus and sitting next to clean-shaven working citizens. I guess it was funny at the time.

Weird Al is still out there, putting out albums and making appearances for some kind of cult following. But he missed his opportunity to get back into the mainstream by tagging on to the Orange Revolution. “Yankovic ” must be an Americanization of something awfully close to “Yanukovich”. It would have been pretty neat for Weird Al to have gone to Kiev to denounce “Weird Vik Yanukovich”, who might have been a 6th cousin or something. Al might have finally gotten a chance to have been taken seriously. Say he had given a concert and put out an album “Weird and Orange, Live in Kiev”, including a cover of “Everyone Knows This Is Nowhere” and “Comes A Time” from Neil Young’s Freedom album . . . it might have put Al on the map. It might have said that even the cheesiest elements of American culture care when an oppressed people longs for freedom. But no, Weird Al sat it out, hoping that his recent “Poodle Hat” album will keep him working. Well, Al, good luck. Fate stops at your doorstep once in lifetime, and you slept right thru it. Pleasant dreams.

Music ... Politics ...

I was just reading an article on the Washington Post website about former V.P. Al Gore. It seems that Gore had a “defeat party” in early 2001 after the Supreme Court slammed him. John Bon Jovi and Tom Petty were there, and Mr. Petty sang “I Won’t Back Down”. Nice, but it was too late for that song. If I were Gore, I would have had Bon Jovi modify the lyrics to one of his signature tunes: “Shot thru the heart, and you’re to blame, baby you give democracy a bad name”.
