Would it surprise you to learn that you can use the Socratic method to help students "discover" music notation AND explore why it exists as it does?
Maybe it's a stretch, but I had in mind to use a Socratic-/Inquiry-based model to teach notation to a General music classroom somewhere between 6th-12th grades. Allow me to demonstrate with a hypothetical dialog... and let me know what you think I could improve on. Thanks!
-----------------------------------
[Play a note on a piano or any musical instrument.]
Class, think about trying to "write" this note for someone else to play. What could you use?
[Confused looks from students...]
Well, what do we use to write words?
"Letters!"
Good! So, someone come to the board and show me how you would write "circle."
[student comes up to the board and writes "CIRCLE"]
Okay, someone else show us another way to write circle.
[Eventually, a student will come up to the board and draw a circle]
So, are words the only thing we use to communicate?
"No. We can use shapes."
Great! So, we can use words or shapes to communicate. What are the simplest shapes we can use?
"Circle/Square/Triangle"
Good. Which one of these can you draw the fastest without changing the shape?
[Confused looks... maybe some guesses]
Let's play a game. I need three volunteers. [Hands go up, pick three students to come to the board]
Let's time who can draw the most triangles, circles, or squares the fastest without changing the shape in ten seconds. Countdown from 10 to 1, class. Ready? Set. Go!
[Circles should be the fastest because there are no angles in a circle]
So, if we wanted to use the fastest symbol we can write accurately, which one would we use?
"Circles!"
Great. So, let's use a circle to represent this pitch. How do we know what pitch it is?
[Confused looks]
Is this higher or lower than this note? [play a note higher or lower than the original note]
"Higher/Lower"
So, how could we show the difference between these two pitches? Someone come up to the board and show me.
[student will more than likely draw one circle at a lower part of the board and another note at a higher part of the board.]
Great, so this pitch is this note, and this pitch is that note. [Play both notes as they relate to "higher" and "lower" pitches.] Let's have another note. [Play a different note]
Someone draw that note on the board compared to the other two notes. Here, I'll play them again.
[student comes up to the board and draws a third note]
Okay, so we have three notes. (Lets assume kids already practice "scales" on an instrument or with their voice)
[Play a major scale, probably the most familiar scale to students]
How many notes did I play?
"Seven/Eight"
Which is it, seven or eight?
[Make students explain why it's seven or eight.]
"It's eight, the top note sounds the same as the bottom note, but it's higher." (Almost correct)
"It's seven, the top note restarts the scale." (Actually correct)
If we use symbols to locate pitches, what can we use to "label" them?
"Letters."
Okay, so what letter should we start with?
[students may call out any letter of the alphabet]
Think about the alphabet. What letter did you learn first?
"A."
Would it be simpler to begin with a random letter or the first letter of the alphabet?
"The first."
I agree. So, let's start with A. What's next?
"B." Next? "C, D, E, F, G..."
How many letters is that?
"Seven."
Do we have enough letters to locate each pitch of the scale?
"Yes."
Great!
If we can draw circles to represent pitches, and we can label those pitches with letters, is there a way for us to show which circle represents which pitch without using letters?
[Confused looks...]
Can we use lines and spaces?
"Maybe."
Let's check. [Draw two or three lines and some circles/ovals, making sure to include the use of at least one line and one space] Is this note in this space higher or lower than the note on this space?
"Higher/Lower."
Good, so we can use lines AND spaces, right??
"Yes."
Dialog to be continued...
--------------------------------
And yes, I'm assuming quite a bit here in terms of what students will shout out and what they'll struggle with, but it's piecemeal enough to explore the foundation of notation and give students the opportunity to "think" about the symbols they use. If they're instrumentalists, they might fall back on music they've seen and jump ahead. Keep them on pace with the dialog and follow-up with questions if they're not arriving at the basics they need for understanding notation. This dialog can go on forever, but I absolutely think a basic understanding of notation from this method will lead to inevitable discoveries about "intervals," "scales," "enharmonic spellings," and so on if continued over several class sessions, broken into concepts. It may enhance the experience of practicing as well, as students begin exploring the fundamentals while practicing their music will awaken more cognitive processes... leading to a musical meta-cognition of music theory and performance.
But yeah, thought I'd just perform the exercise and see what I could come up with and more or less "simulate" here. What do you think?
