The word is from Greek, “poly” meaning many and “phony” meaning voice. This is as opposed to monophony — one voice. Originally, polyphony literally meant multiple people singing together. Over the course of musical history, the term has become more abstracted, referring to multiple “voices” played on any instrument. And usually, polyphony means that the …

The Nirvana effect
I’m currently working on a book chapter about the use of video games in music education. While doing my research, I came across a paper by Kylie Peppler, Michael Downton, Eric Lindsay, and Kenneth Hay, “The Nirvana Effect: Tapping Video Games to Mediate Music Learning and Interest.” It’s a study of the effectiveness of Rock Band …
Sonic analysis of “Tightrope” by Janelle Monáe
The most fun Music Technology class I’m taking this semester is Advanced Audio Production with Paul Geluso. A major component of the class is learning how to listen analytically, and to that end, we were assigned to pick a song and do an exhaustive study of its sonic qualities. We used methods from William Moylan’s …

Toward a better music curriculum
I love music grad school and am finding it extremely valuable, except for one part: the music theory requirement. In order to get my degree, I have to attain mastery of Western tonal harmony of the common practice era. I am not happy about it. This requirement requires a lot mastery of a lot of …
What is an octave?
Octaves are notes that you hear as being “the same” in spite of their being higher or lower in actual pitch. (Technically, notes separated by an octave are in the same pitch class.) Play middle C on the piano. Then go up the C major scale (the white keys) and the eighth note you play …
Secondary dominants
When I was a kid, I’d listen to music and wonder, why is this chord progression so much more satisfying than that one? Now I know the answer: secondary dominants, chords that temporarily change the key in a logical-sounding way. If you want to take your songwriting in a more sophisticated direction, you definitely want …
How do you know what key you’re in?
It’s hard to figure out what key a piece of music is in. There are a lot of conflicting answers from different music theory texts. To make matters worse, it’s not at all unusual for a song to change keys, even within a section or phrase. Even rock songs written by totally naive songwriters can …
Harmonica guide
I started learning harmonica in high school. It was the first instrument I learned voluntarily, not counting my ineffectual middle school attempt at classical cello. As a teenager, my obsession with the Grateful Dead was at its high water mark. The Dead’s first frontman, Ron “Pigpen” McKernan, was a more than respectable blues harmonica player. …
The major scale and the circle of fifths
I studied music theory for a good long time before it dawned on me that you can read the major scale right off the circle of fifths. Here’s the C major scale on the circle. The white notes are the ones in the scale and the black ones are the ones outside the scale. The …
Diminished chords and the blues
The blues is a good entry path for beginner guitarists. If you learn the standard fifteen chords and the blues scale, you’ll be well on your way. However, there’s one crucial piece of additional music vocabulary you need to fully inhabit blues tonality, and that is the mysterious diminished seventh chord. To make a diminished …
