The Dunning-Kruger Effect

The Dunning/Krueger Effect is one of 19 Social Biases (go HERE for a visual guide to many others), also known as superiority bias, the “Lake Woebegon” effect, or superiority bias. We’ve all met someone like this, and may even be like this ourselves if we don’t pay attention. As far as I can tell, it works like this: people who are less able (let’s say a beginning musician), don’t have the skills to make a correct assessment of their ability and tend to overrate their expertise. They think they’re better than they are because they lack the awareness to know any better. I’ve seen this all the time with very young students who finally “get” a simple song and are elated, full of vim and vigor because they think they’re good. And in a sense, they are, they’re better than they once were, they’ve triumphed over something difficult. But they lack the range of experience to clearly understand that they have a loooong way to go. Watch the tryouts for American Idol and you’ll see LOTS of this, some of it quite hilarious or heartbreaking, depending.

The weird thing is another side of the DK effect: those who are competent tend to underrate their expertise. The bashful expert, the sheepish performer, the self-deprecating. Chances are such folks wrongfully assume others have equal understanding and this bleeds them of confidence. They don’t really believe in their greater expertise perhaps also becasue of an awareness of how much there really is to know, and this also makes it difficult to build confidence.

Major Scales and Their Kin

A series of lessons in which I explain the major scale, all its modes, relative minor, Major and minor pentatonics, and the related blues scale. I posted it to help trumpet players learn the fingering of their scales, but the concepts can help anyone and getting the sound of each scale into your memory is essential.

Nudge-Nudge, Wink-Wink, Say-No-More

It’s tough to change our behavior radically, or even significantly. It’s easier to give ourselves a nudge towards utopia. Some real-world examples of the nudge are putting fruit at the front of the school lunch line instead of pizza, because hungry kids (and let’s face it, adults, too) often grab whatever is closest to hand; or the new Illinois policy that changed the wording for the organ donor program so that drivers have to explicitly opt out of being an organ donor instead of signing up to participate in the program, a simple change that saves the lives of many. These nudges are examples from Cass Sunstein and Richard Thaler’s book Nudge: Improving Decisions About Health, Wealth, and Happiness. In the book they suggest useful nudges that help us behave or perform better than we might otherwise. Others are from A. J. Jacobs, author and personal experimenter extrordinaire.

Scale It Up (part Deux)

More in the practical realm this week, continuing the scale-related theme started last week. Here are some patterns to consider for your scale practice. Because it’s so pervasive and is used to explain many aspects of music theory, I’m going to use the Major scale as a reference, and particularly, its numbers, like so:

Major Scale = 1, 2, 3, 4, 5, 6, 7, 8

Scale it Up

If Music is genetic material, scales are its DNA. This is true for most music, anyway. Scales won’t help you much if you’re going to perform John Cage’s 4′ 33,” or if you’re interested in Inupiat shamanistic drumming, but scales will get you through just about any other music, from any culture (as long as you choose the right scale to practice) and they’re invaluable material for use in improvising.

As I started putting my thoughts together on this topic, I realized that a complex set of information is bewildering without tools to make sense of it all. There are so many scales, and so many ways to practice them that it can be difficult to keep them all straight. So I’ve created some tools to help you keep track: checklists, scales, and a few other things. Checklists are making headlines lately (New Yorker article here) because they’ve been shown to improve performance significantly (it’s why pilots use them).

Why you SHOULD demonstrate inability

Attempting the impossible in order to improve is very different than attempting the impossible because you don’t know any better. A few posts ago when I wrote of the useful technique of chaining and backchaining, as an example I told the story of my disastrous high school attempt to play the Hummel Concerto in Eb 25 years ago. This was an example of not knowing any better, and the experience did a fair amount of damage to my teenage psyche and had a temporarily adverse affect on my pursuit of music.

Many years later, as I entered Northwestern University for a graduate degree in music education, I attempted another seemingly impossible music endeavor, but this time I was doing it consciously in order to improve, and was scared spitless.

Grow an Inner Carrot, Forget the Stick

One thing the research record tells us is that incentives and other forms of extrinsic motivation don’t work very well to motivate us, nor do punishments. Carrots and sticks only work if you’re an ass. Much better is motivation that comes from within, or intrinsic motivation. And sometimes training can be a hindrance, too, as you’ll see in the vid below. Because I’m buried in research, I don’t have much time this week to post a lengthy article, but this thought-provoking TED talk is a great way to see the real-world example of how incentives often mean horrible performance, and training isn’t always a good thing.

Book Review: The Musician’s Way, by Gerald Klickstein

I’ve read (and re-read in many cases) most books out there on practice and this is one of the best, hands down. Klickstein is a classical guitarist who performs throughout the U.S. and internationally and is a professor at the University of North Carolina School of the Arts.

My favorite 2 aspects of the book are…

Chaining and Back-Chaining

Whenever I hear the “Concerto for Trumpet in Eb” by Johann Nepomuk Hummel I have this flashback: I’m once again in high school, about to perform the Concerto (on a Bb trumpet). It’s an ambitious piece for any trumpet player, let alone a high schooler; let alone a kid from rural Alaska who has had no lessons. I’m nervous, of course, but I’ve practiced (or so I think), I’ve worked with my excellent accompanist a few times. I’ve never performed it before but I don’t give this much thought because I’m too nervous. I sit in the warm-up room and practice a little before I go perform. That’s not true. I practice a LOT. It’s becoming frighteningly clear to me–much too late–that I don’t really know this piece. I work the sections that are difficult (there are a lot) and begin to get tired. My chops are getting tender. I stop practicing and go perform with a feeling of trepidation in my gut.

Remember Your Thrills On Blueberry Hills

Turns out drinking blueberries boosts memory and improves learning. A recent study from the American Chemical Society said that, “These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration.”

Michel Godard Plays a Serpent

This is an excellent musical performance, and interesting to boot! The frame drum solo at the beginning drew me right in, and when Michel Godard began to play the serpent I was entranced. Godard’s ear and lip control put him completely in tune with the singer. A haunting mix of sounds. Vocals are provided by Linda Bsiri, and the masterful tef playing is by Jarrod Cagwin . According to the comments it’s both a sephardic tune, La Rosa Enflorese and is also known as Los Biblicos, traditional. I don’t know how accurate those comments are. Facts on the Internet are like notes on a trombone: Infinite in number, but most of them are wrong.

Good In, Good Out: Listening

Sound has an impact on us, a profound one. Whether it’s research showing that musicians can detect pitch difference language better; the discovery by Dana Strait–a friend and musical colleague of mine at Northwestern–that musicians are better at identifying emotion in sound; that trees communicate with sound; or that sound can also affect human development in a negative way as presented by Julian Treasure below in a six minute video.
