I wrote a song to help my students with key signatures

Yesterday I was sitting in on a colleague’s theory class, and when she said that it was time to practice identifying key signatures, everyone groaned. I feel their pain and want to help. I myself learned the key signatures by reading and writing a lot of music in lots of different keys and eventually just …

Joy To The Modes

The best way to teach the diatonic modes is to compare them to each other in parallel. One way to do that is to just run up and down them scalewise, but that isn’t very musically satisfying. So I thought, how about putting a familiar melody into all the modes? I wanted one that touches …

Understanding intervals

There are two ways to understand intervals: the right way, and the way I learned them. Before we get into that, let me point you to some good resources for learning the right way. I like the online tutorials by Robert Hutchinson, Chelsey Hamm and Bryn Hughes, musictheory.net and musicca.com. I really love Nate May’s visual …

The bottom number in time signatures has always confused me

The top number in a time signature is easy to understand. Is the song in four? Count “one, two, three, four.” Is it in three? Count “one, two, three.” Is it in five? Count “one, two, three, four, five.” That’s all there is to it. However, the bottom number is another story. What is going …

Identifying plagal cadences

This week in aural skills, we’re working on various harmonic tropes based on IV-I root movements. This chord progression is technically called the plagal cadence, but is more memorably nicknamed the “Amen” cadence because it’s a traditional European hymn ending. (It has nothing to do with the Amen break, though they do sound good together.) …

Polymeter vs polyrhythm

As I continue to build groove pedagogy resources, I want to clear up some persistent confusion about polymeter and polyrhythm. If you don’t feel like reading the whole post, it can be summed up in this image: The most concisely I can put this into words: In polymeter, the grid lines are aligned, but the …

A nice thing happened with my music theory songs

A Twitter acquaintance wrote me this series of DMs: I am so glad he had that reaction. I haven’t been pushing my music theory songs too hard because I wasn’t sure about their value to anyone other than me. I did use some of them in my New School music theory class last semester, but …

Led Zeppelin and the folkloric integrity of the blues

There is a fascinating moment in “When The Levee Breaks” by Led Zeppelin where Robert Plant plays a very flat ninth on the harmonica. I love this note, because there is so much music theory and history encoded within it. Listen at 0:41. Before we can get into the details of this note and what …

The diminished scale

When I want my music to sound mysterious, the diminished scale is a reliable tool in the harmonic toolkit. It worked for John Coltrane and Thelonious Monk, and it can work for you!

Just intonation and key changes

Western people like two things in harmony: intervals derived from the natural overtone series, and the ability to play in multiple keys. Unfortunately, it’s not possible to do both of these things within the same tuning system. If you want to use just intonation intervals derived from harmonics, then they will not work in every …
