Music, the brain, and science

Middle School Diana Deutsch lesson
I just taught this to my older students and I've got to tell you about it!  When I did some work for The Boston Symphony, I contacted Diana Deutsch of the University of California, San Diego.  I never used her work on the modules for the BSO, but I continue to be intrigued by her research.  This lesson is especially exciting when you mention to the children that Audacity is a shareware (free) opensource program that they can download and do these experiments themselves.

This is my favorite CD from Diana Deutsch.  It is the one
whose examples I played for my class.
I used this information as little snippets within a choral lesson.  I'm introducing some holiday pieces and, each time the students sang particularly well, I gave them some "ear candy" in the form of a new aural illusion or example.  For example: we began rehearsal for "Come Follow Me" by Linda Spevacek.  Students learned the A section on solfa and sang it in tune with proper syllables and a good, strong voice.  Their reward was to hear the phantom word illusion.  In this illusion the students hear two, one-syllable sounds spoken together.  With repeated hearing, the brain turns these chaotic sounds into words, sound effects, or other illusions.  I didn't tell students what they should hear, but asked them what they did hear.  Their answers were amazing!  One child heard a Spanish word. Another, a phrase about tests.  Still more heard silly words.  Here is a link to what my students heard.  What do you hear?

The children learned some other material and I gave them some more "ear candy."  This time it was the illusion of singing within speech.  Listen to this sentence.
Phantom words and phantom singing, just in time
for Halloween!
Thomas Jefferson and I raw
A typical sentence, right?  Well, let's see.  What if I play part of that sentence in a loop?
Thomas Jefferson and I loop
Now that you've heard that loop, go back and listen to the original clip.  Do you sense that this young man is suddenly breaking into song in the middle of his sentence?  That's the illusion!  It's also proof that speaking is singing and singing is speaking.

Here's another one.  I got this young lady to overcome her self-consciousness by talking about something that she finds annoying.  Getting their ire up is great for having them exaggerate inflection.  This also works when you have teachers discuss the teaching process, have a person talk about a hobby, or having a new parent talk about their baby.
I really don't like yogurt
Here's the loop.
I really don't like yogurt loop
What really jazzed my students was that they could download audacity and DO IT THEMSELVES!!!  I was so psyched!  Students who ordinarily need so much pushing were singing like canaries today, so anxious to hear the next illusion.

D, Popsicle Stick and Paper Plate Kalimba!

Back to the Orffabet! Today's letter is D, the shape of the popsicle prongs on a homemade Kalimba!

Lisa Lehmberg of the University of Massachusetts, has agreed to share this portion of her book chapter. Hurray, Lisa! Let's make a Kalimba out of popsicle sticks, paper plates, and some scrap wood!
You'll need: two small, sturdy paper platesone wood block (3cm x 7cm* x 1cm) To convert to inches click here.  This block is inside the plates and keeps them from collapsing.7 cm* piece of thin plywood five flat popsicle sticks7 cm* strip of flimsy wood moldingbrads or small screws (optional)paper gluewood glue*the length is determined by the size of the paper plates. These measurements are for the structural stability of the instrument, NOT the intonation. Just eyeball or loosely measure the wood.
Glue a block of wood to a paper plate near its edge. Glue another paper plate (plates facing each other) to the original plate and the wood block. Spread glue on both the rims of the…

Liquid Ass

So we've had another school shooting. By the time I post this, we will have had a few more. The NRA and President Bone Spurs would like us to arm teachers. Shooting another human being is not natural. Killing is not natural. Self-defense only feels natural when hand to hand combat is involved. Guns, even in the heat of  battle, are abstract. Perhaps the primary reason the United States has a volunteer army instead of a drafted one is that drafted soldiers are far less likely to actually fire at the enemy when the time comes. The kill instinct has to be trained into a soldier. It isn't natural, and it takes its toll on the soul. Plus, you'll probably miss and shoot an innocent student and die anyway.

So I offer a humble alternative. Well, maybe two, but one of them is actually entertaining.

1. ALICE training. Click on this. It's helpful.
2. Liquid Ass


Developed as a joke product, Liquid Ass makes an excellent deterrent to the progress of a shooter. Shooters expect thei…

"P", The Bucket Routine for older students

Today's Orffabet letter is P, for the shape of buckets and sticks when they are in storage in our guest teacher's classroom.

The following post and series of videos is for Upper Elementary, Middle School, or High School Students.  This is a rare opportunity for you to learn a routine without having to go to a workshop or Orff level.  You will learn the routine as your students would.

John is a teacher in the Worcester Public Schools.  He has taught this routine to Upper Elementary students as an after school program.  John's students worked on the routine for an hour or so every day for 6 weeks.  To see John in an earlier post, click here.

The "students" in this video are Orff Level I students in the Worcester Public Schools class of 2010.  They learned the routine in a 90 minute session with Level III students who already knew it.  Here is the routine after those 90 minutes.

This routine, inspired by African dance and Orff body percussion, is well outside the …
