Exploring the Human Voice - Part 1: The Lowest Note

The human voice is capable of producing some amazing sounds. A number of delicate organs in the mouth and throat can be taught to modify the color, tone, and timbre of a person's voice and provide quality and variety unmatched by even the grandest piano. I will dedicate the next couple of posts to exploring the outer reaches of what the human voice is capable of.

To find the lowest extreme, we must look to Mozart. The aria "O, wie will ich triumphieren" in the opera "Abduction at the Seraglio" contains the lowest note in the classical repertoire - D2 (see above). What could have compelled Mozart to write such a low note? True, he was writing for a bass singer with an extraordinary range. Still, the music itself needed to have the artistic integrity to reasonably incorporate such a bizarre element.. Mozart couldn't just stick a very low note in the aria, and he knew it. It's no good to create weird music for the sake of being different or weird. The low note must carry a meaning aside from its peculiarity. So, Mozart made it part of a musical theme in the aria. This 7- note theme goes with the words "denn nun hab ich vor euch Ruh." The theme is quite simple, merely 5 notes descending in whole steps from A3 followed by 2 notes re-ascending, also in whole steps. See?

But this simple, benign theme actually sets up a witty and delightfully cruel joke, which, for a genius like Mozart, is easy to see but for us is quite surprising. After a brief pause, the theme is repeated, only the first note is an entire octave lower than before - at A2. As before, the theme descends 5 notes to D2. Again, this famous note D2 is the lowest sung note in the classical repertoire. Reaching it is no easy feat. Perhaps showing uncharacteristic mercy, Mozart allows his theme to jump to a more comfortable A2 before having the bass sustain the long note. Despite having to reach D2, this was the easy part.

The theme pops up again at the end of the aria. This time, it follows a difficult coloratura section in which the bass must sing an elaborate tune full of runs up and down on the musical scale. As you can see below, right before beginning the "denn nun..." theme, the bass is required to go from E2 up to A3 and then back down to A2 in one step. That bit is tiresome, but Mozart affords the bass only the tiniest rest before beginning the "denn nun" theme.

The familiar 5-note cascade begins again - this time on D3 (see above). Uh-oh. If on the first go-around, we descended an entire octave for the repeat, does this mean that this time, the repeat will begin at D2? That's what the rules tell us, but Mozart is making up the rules and he does something way more ingenius.

The repeat begins not an octave lower, but at the same spot. Barring a couple of minor semi-tone changes, the repeat is exactly the same as the first run. This means that, according to the rules, this theme will end relatively easily for the bass. On the ascent in the second repeat, he'll jump up to a very comfortable D3 before having to sustain the long note.

But no! Instead, Mozart makes him go DOWN - down FOUR steps to D2. The bass is now faced with the sickening challenge of holding a D2 note for 8 bars.


I've heard many basses try to do this aria. Only one I've heard has done it convincingly. He's not the one in this video, but unfortunately this is the only one I have on video. Time cues are in the text to the side.

MIT student hijacks Logan Airport with Play-doh

This morning, an MIT Course Sixer in her sophomore year was arrested at Logan Airport for wearing what authorities purport to be a fake bomb.  More info here.

Now, yes it was dumb to wear something like that considering the state of mind of the country. You can't assume that people are aware of the close to nil chance of terrorists making American airports a target again. You also can't assume that even if they were aware, that they would give you the benefit of treating you reasonably. Or would they? Any reasonable person would be acutely aware of people's reaction to such a device because of course we are all still buying into that "terrorists will follow us home" political rhetoric. Oh wait, MIT people - not reasonable. Informed.

She wore this circuit board with an LED star on it because her name is Star, and she wanted to make an unusual impression during Career Fair. It was a piece of art, in retrospect, a brilliant one. This "bomb" managed to cause a national crisis despite consisting of components as mundane as morning cereal. I've heard from more than one alumnus that coming into contact with the outside world is shocking to the average MIT student. Apparently, it's just as shocking to the world.

She was later released on $750 bail, and still faces charges of disturbing the peace and possessing a hoax device.

I am typing on my iPod touch

niiiice. its pretty easy to type using the keypad. I don't think its a substitute for a computer, but its a close substitute. Much better than anything else that's portable.

Technology: Xerox

I cannot get over how amazing technology is.

As tech guy for the Women's Studies Office, I should know a bit about technology, and indeed I do. I'm practically (not officially) a certified networking administrator. I've worked out in the field doing networking jobs, and I'm comfortable in most computer environments.

For all that though, one piece of technology still scares the crap out of me - the copier. Even scarier, Xerox machines. They're easily the largest piece of technology most of us ever have to work with. And on this huge piece of metal and plastic, there is only a small keypad with a tiny screen for you to interact with. To this day, I have no clue how to do most things with a Xerox machine. It takes me minutes to figure out even how to get something to print normally. Some people use the tray on the top because it's easier but not me, no siree. I use the glass.

As tech guy, sometimes I have to do printing jobs. Like this weekend, I had to get some readings scanned for and emailed to a professor in the department. So I thought, okay I'll use the scanner and Acrobat Pro to create each document as a PDF. I sat down on Thursday and started doing the first document, which was about 20 pages long. I put the first page down on the glass, hit the scan button in the Adobe plug-in, and it scanned the first page. I removed the first page, and loaded the second. I hit the scan button, and let it scan. Removed the page, loaded the next page, hit the button, let it scan. Removed, loaded, hit the button, scan. I finally finished after about 30 minutes. Unfortunately, I still had a huge stack of documents that still needed scanning. Oh yeah, and then I had to email them all - in separate emails, according to her order.

I went home after that first document, figuring I'd email Emily and get her to find someone to do some and I'd finish the rest later. Well, I emailed her and she suggested I use the Xerox machine and finish myself on the weekend.

I went to the office Sunday, fully expecting I'd need to download the machine's manual and pore over it for an hour to figure out how to scan and email documents. As soon as I came into the office, I became overwhelmed with a sense of laziness. I decided to see if I could go it alone. I grabbed the first reading, the one I had already scanned on the computer, and approached the Xerox machine. It was standing quietly on its side of the room. I lifted up the glass and it lit up and started humming. On impulse, I put the glass back down and looked at the tray. It had a nice little graphic showing a person putting a paper in the tray, so I put my papers in the tray like the guy in the picture. The machine made a clicking noise, like a hammer being cocked. Now, I looked at the little screen and the keypad. I saw a Scan/Fax button and pushed it. A window came up on the screen showing names of people in the office. I pushed mine. My email address came up. I didn't know what to do next, so I just hit the START button. Immediately, the machine started rumbling loudly and sucking the sheets of paper down and then just as quickly spewing them back out onto another tray. Before I fully knew what was going on, it suddenly stopped. I hesitantly retrieved the pages from the tray, shuffled them...they were all there. Cautiously, I went over to the computer and checked my email...and there it was. An email titled "Scan No.459295" (or whatever it said) with an attached PDF file. Holy cow, this thing had done in ten seconds what had taken me THIRTY MINUTES to do.

Technology is amazing.

Film Review: Halloween

I'm not much of a horror flick kind of guy, but when I heard Rob Zombie was going to direct the new Halloween remake, I knew I had to watch. This afternoon, I went to see it with my sister at the Loews in Boston Common.

The film is divided into two stories, roughly 50 minutes each. The first part takes place when Michael Myers is a child and vividly portrays the depraved and horrific life he lived as a child, perhaps giving us a reason to pity him. His step-dad is a lazy, abusive drunk who makes fun of Myers' slight femininity. His mother loves him dearly, but is unable to teach him any sense of morality. Kids tease and bully him mercilessly at school because his mother is a strip dancer, and his older sister is too preoccupied with her sexuality to give him much needed friendship. His only refuge is a clown mask that he wears whenever he feels scared or vulnerable, and his only past time is killing small animals. No surprise, then, when Myers explodes and goes on a killing rampage. Seeing a child commit such brutal acts of murder was...chilling to the core. Yet, a small shred of sympathy did linger in my mind. Why? Because the brutality of his childhood is fleshed out brilliantly by Mr. Zombie. Credit must also go to the cast, especially the kid who plays Michael Myers and the woman who plays his mom. This first half of the film is excellent. The second half...not so much.

Part Two takes place fifteen years after Myers is taken to an insane asylum. He has acquired many more masks and has grown to gigantic proportions. He towers over the security guards and when he is taken out of his cell to get transferred to another facility, he easily escapes. He makes his way back to the town in which he grew up in order to find his younger sister, who had been a baby when he went on his rampage. Without giving away too much, the rest of the film pretty much becomes a slasher movie, in which several teenagers get taught the hard way not to have sex. Unfortunately for this part of the movie, there are only a couple of suspenseful moments, one involving a girl's father and the other involving Myers' psychologist. The rest is gory without being scary.

In order to properly establish this film's place in horror film cinema, I'll probably have to watch the first one. If it was able to establish Myers' childhood as well as this one did or better, than this film is a failure. I doubt, however, that even the original could best Rob Zombie's treatment of the story. Yes, the second act lagged, but the first half, I believe, more than makes up for it.
