…and because I haven’t posted anything new in months, here’s another from Facebook. I really should start taking advantage of WP more often.

Instead of making a frantic note about how I skipped Psychology today so I could practice for my audition coming up on Saturday that, incidentally, will determine the rest of my life, or telling you about how many times I’ve slipped on icy walkways and staircases and broken both hips and a tibia, or even recounting the fun I’ve had over the weekend rearranging my entire life in boxes and bags, I’ll write about a pun from today’s music theory drill.
In music, there are phenomena called periods and sentences. They are both structures commonly found in all sorts of compositions, from Mozart’s to Mendelssohn’s. Both are comprised of a series of phrases (two with periods, three with sentences), or shorter musical ideas. The main difference between them lies in how they are perceived by the ear: periods seem balanced and are theoretically symmetrical, while sentences act like a rubber band (more on this later).
There are many different classifications of periods, each with a specific function either melodically or harmonically. By far, the most used type of period in western music is the parallel interrupted period. It is labeled as such for these characteristics
- Parallel–the melody, or melodic material, is repeated twice (once in each phrase) with little or no variation.
- Interrupted–the harmonic structure is literally interrupted. The first phrase ends on a weaker cadence (perhaps unresolved), so it begins again in the second, resolving logically and on a stronger cadence as the period finishes.
The sentence acts in much the same way–that is, to present a concise, measurable chunk of music–but its effect is much different from that of the period. To extend the rubber band analogy (hah), consider the potential and kinetic energy of stretching it back and flinging it across the room. The energy is stored, then released when it is let go. In relation to the sentence, the first half (or so) of the musical idea acts like it is stretching the rubber band, creating lots of tension; likewise, the remainder of the sentence becomes the result of letting it loose and hitting someone in the eye.
The first half of the sentence, or the presentation, consists of a short bit of music repeated twice. However, there is no cadence, no point of rest. It works its way to the continuation (which may or may not borrow some of the melodic material from the presentation) and ends up at some kind of cadence a few bars later. [Here is where the pun comes in, though it isn't necessarily funny. The instructor said something to the effect of, "You can't have a point of rest in the middle of the presentation; you would lose the effect of building it up. You'd diffuse all the tension." I heard "diffuse" and "defuse," both of which made a lot of sense, first literally, then metaphorically. I used a rubber band analogy above (albeit a bad one), but "defuse"...I mean, the musical sentence could be like a time bomb of sorts. Tension piling up as the fuse burns down, then the explosion, an outpouring of sound; then the cadence–dead silence]
All right. I know that might have been a bit tedious, or dare I say, boring. But I’m not apologizing for any of it. Call me what names you will, but this fascinated me to no end. The concept of music relating to life and humanity as a whole is mind-blowing. I don’t even know where to start, but I guess this seemed like a good place.
[Later that day...]
I’ve recently taken to working out at the gym on campus. I’m trying to keep a relatively regular schedule of Sundays, Tuesdays, and Thursdays every week, for about an hour and a half to two hours each day. My routine consists of stretching, jogging and running, a short core workout (courtesy of Julie) and then a bit of time with free weights.
Tonight (being Tuesday) I went at a rather late hour, probably not making for the most efficient workout. However, I hadn’t gone on Sunday because I was busy moving house (one of the best decisions I’ve ever made, by the way) and I also felt like I needed to get away. When I’m there, my mind goes blissfully blank. I don’t think about anything, not classes, not homework, not the fact that the culmination of seven years of practice will come this Saturday…nothing. Right now, my mind is consumed with hypothetical thoughts of eminent failure across the board. I’m generally keeping up in classes, so I’m not falling behind. Yet. I know I have the potential to succeed (doesn’t everyone?), but more prevalent in my mind is the fact that I still have the potential to suck. I try hard to keep those thoughts at bay, but after a particularly bad practice session this close to D-Day, it becomes almost overwhelmingly difficult. Going to the SRSC has become something of a crutch, but without the negative undertones. It’s benefiting me twofold, and I think only good can come of that.
Even though I haven’t really done anything yet, this evening seems to have been very productive. I’m in a good place right now: showered, fed and watered, listening to some muttered German vocabulary words over the sounds of Christopher O’Reilly playing Radiohead. Life is…well, life is life. The snow is still falling relentlessly, but at this point, I don’t think I could chill out if I tried.
Let me know if any of my theory is incorrect. This is still relatively new to me.
