Seventh chords in just intonation vs 12-TET

I enjoy listening to Jacob Collier explain his music more than I enjoy the music itself. His arrangement of “Moon River” is mostly exhausting. However, Miles Comiskey pointed me to an interesting moment in this explainer video at the 1:04:22 mark where Jacob talks about how Kontakt enables you to change your instrument tuning on the fly.

Jacob takes a dominant seventh chord and plays it in two different tuning systems: twelve-tone equal temperament, the system we’re all used to, and just intonation, which is a more “pure” harmonics-based system. The chord sounds very different in the two systems. That is a profound musical concept that is not easy to understand! Jacob buries it in his song under five thousand other ideas, but I thought it would be helpful if I built a whole track around it:

Let’s analyze Alexander Scriabin incorrectly

I get academic articles in my email from various lists that I’m on, and this was an interesting one: “The Pedagogy of Early, Twentieth-Century Music: Ideas for a Classroom Discussion based on a Multi-Faceted Analysis of Scriabin’s Op. 31, No. 4.” by Michael Chikinda. Here’s the piece he’s talking about:

I don’t know Scriabin’s music very well, and I liked this immediately, so I wanted to know more. Journey on with me!

Dual tonicity in a classic klezmer tune

I’m rewatching Curb Your Enthusiasm and very much enjoying the work of music supervisor Steven Rasch. In season five, episode eight, Larry pretends to be an Orthodox Jew to win over the head of the Kidney Consortium. To soundtrack the scene where Larry first meets the guy, Rasch chose a classic klezmer tune, “Tanz Tanz Yidelekh”, which is Yiddish for “Dance dance Jews.” Yes, that is the title.

I played this tune with F Train Klezmer back in the day and it’s a beauty. It’s also quite a music theory puzzle! Continue reading “Dual tonicity in a classic klezmer tune”

Led Zeppelin, “Ten Years Gone”

I like to dip into Rick Beato’s YouTube channel once in a while. He’s too Boomer-ish and curmudgeonly about current pop music for my tastes, but when he rhapsodizes about the 70s rock that he loves, he’s delightful. His list of the top 10 Led Zeppelin riffs is especially pure Beato essence.

Number six on Rick’s list is “Ten Years Gone”, a power ballad from Physical Graffiti and a bit of a deep cut. After this video reminded me that it existed, I went and listened to the song with fresh ears, and I very much enjoyed it. Continue reading “Led Zeppelin, “Ten Years Gone””

Smokestack Lightning

The twelve-bar blues is not the only blues form. There is also a whole world of one-chord blues grooves over drones, pedal tones and static riffs. Howlin’ Wolf has several classic songs that follow this model, including “Spoonful“, “Wang Dang Doodle“, and “Smokestack Lightning.”

Guitarist Hubert Sumlin came up with the iconic riff. The track also features pianist Hosea Lee Kennard, guitarist Willie Johnson, bassist Willie Dixon, and drummer Earl Phillips. Continue reading “Smokestack Lightning”

How guitarists learn music theory

This is me, rehearsing an Allman Brothers song with my stepbrother Kenny for my stepdad’s funeral last summer.

If you are a music theory teacher interested in reaching guitarists, here’s some background on my own music learning that might be illuminating. My journey is a pretty typical one for a rock guitarist, except for the part where I went to music school afterwards.

Research statement

I am finishing my dissertation soon and am applying for full-time academic jobs. Here’s my research statement. Also see my teaching statement.

I have three main areas of research interest: the teaching and learning of rhythm and groove; the challenges of hip-hop pedagogy; and expanding the teaching of harmony to include groove-based musics, particularly the blues. I address each of these areas in turn.

Nahre Sol introduces Billie Eilish to the classical canon

In this fascinating video, Nahre Sol composes accompaniment for an isolated Billie Eilish vocal in the styles of various canonical composers.

The combination of Billie Eilish and Mozart is predictably weird, but not for any “musical” reason. There is not such a wide disconnect between Billie Eilish’s melody and classical music. The weirdness is due to the fact that Billie Eilish is a microphone singer, not a concert hall singer. It’s strange to hear microphone singing over classical-style accompaniment!

The blues and the harmonic series – a visual guide

Does the harmony of the blues come from the natural overtone series? Is it a just intonation system that later got shoehorned into Western twelve-tone equal temperament?

Whether the blues comes from just intonation, or just intonation happens to sound like the blues, this is a rich and promising avenue of inquiry, both for understanding the blues and for creating new music inspired by it. In this post, I use MTS-ESP, Oddsound’s amazing microtonal tuning plugin, to visualize the possible harmonic basis of the blues. Continue reading “The blues and the harmonic series – a visual guide”
