Jacob Collier’s four magical chords

Jacob Collier is the internet’s favorite musical virtuoso. Here’s his mostly acapella arrangement of a Christmas carol called “In The Bleak Midwinter.” The most remarkable part of this arrangement comes between the third and fourth verses, when Collier modulates from the key of E to the key of G half-sharp. That’s the key which is …

Naima

I’ve been doing so much explaining basic music theory that I thought it would be fun to dig into something advanced: “Naima” by John Coltrane, from his all-killer-no-filler album Giant Steps. There are as many interpretations of this tune’s chord changes as there are transcriptions of it. The ones in the Real Book are real …

Developing an intro-level music theory course

In the fall of 2019, I started teaching Fundamentals of Western Music at the New School’s Eugene Lang College. It combines the usual Music Theory I content with a broader, more ethnomusicological perspective that brings in various forms of pop, non-Western musics, and (most excitingly for me) the blues. It’s an existing course, but I …

Why can’t you tune your guitar?

Short answer: because math. Longer answer: because prime numbers don’t divide into each other evenly. To understand what follows, you need to know some facts about the physics of vibrating strings: When you pluck a guitar string, it vibrates to and fro. You can tell how fast the string is vibrating by listening to the …

Giant Steps

This Vox explainer video about John Coltrane’s most iconic tune is making the rounds right now. It’s well made and engaging. You should watch it! “Giant Steps” is a beautiful tune, one that rewards as much scrutiny as you care to give it. But it also had some negative effects on jazz as an art …

Chord pizzas

The Groove Pizza uses geometry to help visualize rhythms. The MusEDLab is planning to create a similar tool for visualizing music theory by merging the aQWERTYon with the Scale Wheel. When you put the twelve pitch classes in a circle, you can connect the dots between different notes in a chord or scale to form shapes. My …

New harmony course with Soundfly

My new online music theory class with Soundfly launches in a few weeks. It’s a six-week mentor guided journey through advanced harmonic concepts like extended chords and modal interchange, with examples drawn from contemporary pop, hip-hop and electronica. Soundfly does great work and I’m proud to be working with them.

The happiest chord progression ever

See also: the saddest chord progression ever. And also check out this deep dive into the groove of “I Want You Back.” We customarily think of descending melodies and chord progressions as being sad–they call it the “lament bass” for a reason. You may be surprised to learn, then, that the happiest song of all …

Teaching myself the Bach Chaconne with Ableton Live

Recently someone posted this performance of the Chaconne from Bach’s violin partita in D minor on an eleven-string guitar by Moran Wasser. My favorite interpretation by an actual violinist is Viktoria Mullova’s. I appreciate her straightforward and unsentimental approach. I also enjoy the version from Morimur, and I’m not alone. It’s one of the most …
