One of the most successful units I've found for equally reaching all my students is a Music and Emotion Unit. In the unit where we look at the ways music is used in media (film, television, video games, online) to help tell stories and heighten emotions.
The typical, minor chords are sad/major chords are happy, is something our students have been introduced to in elementary school, but I feel that statement definitely over simplifies the reasons why music effects emotion. There are several contemporary "upbeat" pop songs like Pharrell William's Happy, Lady Gaga's Just Dance, and LMFAO's Party Rock Anthem that are all written in a minor key. So what makes happy music happy? What makes sad music sad? A lot of research has been done on the topic, and the two videos below give contrasting reasons for how/why music affects emotion. Both come courtesy of a series of videos produced by PBS specifically for their online audience. The first is from the IDEA Channel, which is hosted by Mike Rugnetta.
If you've never watched an IDEA Channel video before, I must warn you, Mike is a fast talker. That being said, I think the videos have a certain appeal to the average middle schooler. They are fast paced with tons of images, and animated gifs pulled from pop culture. As my classes watched the video, I paused it several times, just to make sure my kids were keeping up, and also to explain some of the more advanced terminology Mr. Rugnetta was using. As one girl put it "I really like the video, he was funny. But I'm glad you kept stopping cause I didn't understand a thing he was saying." Hmmm... I guess being funny is more important than understandable.

The second video is the one from It's Okay to be Smart that Mike Rugnetta references in the first video. It's Okay to be Smart is hosted by Joe Hanson, who delivers his message in a more traditional educational style than Mr. Rugnetta (those maybe not as funny). He's very clear with his explanation of why some scientists think music moves us, and it provides a nice counter argument to the IDEA Channel video.

I'd love to hear some of the response your students have to these videos. What do they think? Are we born to recognize the emotional aspect of music, or are we trained?
