Appoggiatura and Adele

The WSJ has a piece about Adele (here), which describes why her song "Someone Like You" is such a "tear-jerker".
Twenty years ago, the British psychologist John Sloboda conducted a simple experiment. He asked music lovers to identify passages of songs that reliably set off a physical reaction, such as tears or goose bumps. Participants identified 20 tear-triggering passages, and when Dr. Sloboda analyzed their properties, a trend emerged: 18 contained a musical device called an "appoggiatura."
An appoggiatura is a type of ornamental note that clashes with the melody just enough to create a dissonant sound. "This generates tension in the listener," said Martin Guhn, a psychologist at the University of British Columbia who co-wrote a 2007 study on the subject. "When the notes return to the anticipated melody, the tension resolves, and it feels good."
Indeed, after hearing that song for the first time I had an emotional response, and impulsively bought it from Amazon with a lingering $1 MP3 credit. The song is really quite good, and stands up to repeat listenings.

The WSJ didn't introduce me to Adele's famous song, but the idea that using Appoggiaturas could manufacture emotional songs piqued my interest.

Looking first using the Googles, I found some songs which enthusiasts claimed to use appoggiaturas, though none provoked anything close to the emotional response of Adele's song (REM's Camera, Steely Dan's Fire in the Hole).  I did discover a nice piano piece, Floyd Cramer's Last Date, but that likewise did not jerk the tears, so to speak.

Another piece I found that used syncopation and dissonance in addition to appoggiaturas was the Banjo by 19th century composer Gottschalk, a piece written for the Piano, but designed to take advantage of the then-popular banjo. I like the piece, but no chills.

Either the WSJ was lying (a possibility, though this seemingly wasn't a conservative conspiracy--their usual milieu) and appoggiaturas were nothing more than standard ornamentalism, , or else I needed to look elsewhere.  So I searched around for some academic papers by Dr Slobada to see if I could find the songs that he used in his experiment.

The most frequently cited papers on this topic seem to be Jaak Panksepp, "The Emotional Sources of Chills", which I looked to for some better examples. Apparently the song which was found to send the most shivers down the spine was Air Supply's Making Love Out of Nothing at All, (in replication by another researcher that number fell dramatically to <10% of listeners).  For myself, I didn't get any shivers.

Other pieces which inspired chills included Pink Floyd's The Post War Dream (no chills for me), Journey's Faithfully (some chills, especially around 1:25 and the end), Boston's Peace of Mind (no chills, but some Boston songs can give me chills), Howard Jones' No One is to Blame (nothing), and Cris Williamson's Wild Things (garbage song, no chills).

The WSJ article offers some hints of other songs and types:
Chill-provoking passages, they found, shared at least four features. They began softly and then suddenly became loud. They included an abrupt entrance of a new "voice," either a new instrument or harmony. And they often involved an expansion of the frequencies played. In one passage from Mozart's Piano Concerto No. 23 (K. 488), for instance, the violins jump up one octave to echo the melody. Finally, all the passages contained unexpected deviations in the melody or the harmony. Music is most likely to tingle the spine, in short, when it includes surprises in volume, timbre and harmonic pattern.
Though the cited example doesn't thrill me, I agree that surprises in volume, melody and harmony can create emotional tension, though whether that tension can be reliably manufactured into chills is another story.

If the sensation of chills can be reliably created through music, I have not seen evidence of it.

Bike Fixing Station

While the idea seems vaguely communistic, I believe that it makes a great deal of sense to have community bike fixing stations, especially in areas with a lot of bikes (college campuses especially!).

Here's one attached to a vending machine, with common parts:

Jolly Pumpkin La Roja

Today's review is Jolly Pumpkin's La Roja.
The bottle has a beautiful label, and I had high expectations, as I had heard that Jolly Pumpkin made some great beers.  Mine said it was bottled April 8, 2011, and came in a 750ml bottle.

The pour was a rich reddish-brown, amber color, and pours with almost no head.
The nose was very pleasant, with sweet cherry and spice coming off.  Very rich.  Nothing to prepare me for the taste, which was very sour.  Probably the best comparison would be sour cherries. Not quite sour enough to make my mouth pucker out, but very close.  To be honest, this beer was much too sour for me, and very different from my expectations (I expected this beer to be much sweeter).

For a beer north of $10/bottle, I was a bit disappointed.  I think there was some nice complexity in this beer, but ultimately it fell short, especially if you are looking for value from your beer spending dollar.

Overall grade:  C+ (B- except for the price)

Extreme Diet may cure Type 2 Diabetes

Eleven people with diabetes took part in the study, which was funded by Diabetes UK. They had to slash their food intake to just 600 calories a day for two months. But three months later seven of the 11 were free of diabetes.

"To have people free of diabetes after years with the condition is remarkable – and all because of an eight-week diet," said Roy Taylor, professor at Newcastle University, who led the study. "This is a radical change in understanding type 2 diabetes. It will change how we can explain it to people newly diagnosed with the condition. While it has long been believed that someone with type 2 diabetes will always have the disease, and that it will steadily get worse, we have shown that we can reverse the condition."

Here's hoping that further study reveals this as an effective and statistically significant source of treatment.  That said, I imagine this treatment will have to be monitored in a hospital setting, as I imagine many sufferers of type 2 diabetes lack the willpower to restrict their diets so drastically.
