Teaching music intervals can be hard, especially when facing students with limited musical backgrounds. Not only must students know their key signatures, but they must remember the differences between minor, major, diminished, and augmented tonalities, all the while using flats, sharps, double flats, and double sharps... But don't despair, because here is a theory crib sheet that will help you towards teaching this topic very efficiently.
I first came up with this poster during a theory class. My DP music students were struggling to find a suitable strategy for naming intervals. I drew this graphic out on a scrap piece of paper, several times, and soon the students had them propped up in front of them. That's when I knew - yup, this is a successful poster. Time to share!
Students are asked to check the bottom note of the interval pair. What key signature should it have? Is the top note correct? Is it a chord tone?
If it's too big, then it's augmented.
If it's just right, then it's either perfect or major.
If it's too small, then it's either diminished or minor.
If it's waaaaaaay too small, then it's diminished.
This poster was used with a Diploma Programme music class, though it would be equally suited to Advanced Placement students or private lesson students as well. I've also used it with my grade 9s, which means it's helpful for high school students in general. It is currently sized for A3, but can be reduced through "fit to page" printing for A4 or Letter sized papers.
Included in the package is an A3 jpg and its accompanying PDF file.
