Learning minor key harmony from the Bach Chaconne

Major keys are easy to understand, at least in classical music, because a major key and a major scale are coextensive. Minor keys are harder, because you can’t just equate them to particular minor scales. To understand how chords work in minor keys, I’m going to walk you through a standard progression that happens throughout the final movement of Bach’s Violin Partita No. 2 in D minor, the famous Chaconne.

Here’s the complete performance by Viktoria Mullova, with MIDI visualization in Ableton Live created by me:

Read more about the Chaconne and hear the Afro-Funk remix. There’s a lot there to dig into! But right now, I’m just going to talk about the first few measures. The opening phrase is four chords: Dm, Eø7 with its 7th in the bass, A7 with its 3rd in the bass, and Dm again.

Together, the chords form a ii-V-i in D minor. In the remainder of this post, I’m going to talk through these three chords and their associated scales in detail. Try them for yourself on the aQWERTYon.

Bach’s Suite for Solo Cello No. 1 – Prelude

I’m teaching melody in music theory class this month, and nobody wrote better melodies than Bach. If you want to learn how to use single note lines to imply chord changes and counterpoint, the prelude to his first cello suite is a whole textbook worth of wisdom for you. My favorite interpretation is by Mstislav Rostropovich.

Music supervisors in movies and television have run this prelude into the ground, as evidenced by Bach’s colossal IMDB page. Noteworthy usages include The Pianist, The West Wing, Netflix’s Daredevil, If I Stay, The Hangover Part II, and, uh, Mega Shark vs Giant Octopus. My personal favorite is in Master and Commander, when they arrive in the Galapagos Islands.

Announcing the Theory aQWERTYon

A few years ago, the NYU Music Experience Design Lab launched a web application called the aQWERTYon. The name is short for “QWERTY accordion.” The idea is to make it as easy to play music on the computer keyboard as it is with the chord buttons on an accordion. The aQWERTYon maps scales to the keyboard so that there are no “wrong notes,” and so that each column of keys plays a chord. Yesterday, we launched a new version of the app, the Theory aQWERTYon. It visualizes the notes you’re playing on the chromatic circle in real time. Click the image to try it! (Be sure to whitelist it on your ad blocker or it won’t work.)

In addition to playing the built-in instruments, you can also use the aQWERTYon as a MIDI controller for any DAW or notation program. Just set the input to the IAC bus (Windows users will need to install MidiOX before this will work.)

Salsa in Central Park

Yesterday I went to a free concert by Johnny “Dandy” Rodriguez and his Dream Team by the Harlem Meer in Central Park. I don’t know a lot about salsa, but these guys sound to me like an excellent salsa band.

Sound writing with my New School students

I just completed the first week of Fundamentals of Western Music at the New School. We began the semester with critical listening. Before having the students analyze recorded music, I had them warm up by doing some writing about the sound of a mundane environment. As it turns out, New School students are terrific and imaginative writers, and I thought I would share some excerpts of their work here.

The internal ear

The assignment: Choose a physical location, and describe its soundscape in 500-1000 words. List all of the sound sources you can and describe them in as much detail as possible. Describe your emotional reactions to these sounds individually and collectively. If you like, review the sounds as if they are a musical work.

Donna Lee

Here’s a Charlie Parker recording that’s not widely known outside of jazz, but is absolutely foundational inside it:

This recording features a very young Miles Davis on trumpet. Miles later said that he wrote the tune, and that its copyright attribution to Charlie Parker was a record label error. I believe him. It sounds more like a devoted Charlie Parker fan emulating his style than something Parker himself would write.

I’m embarrassed to say that my first exposure to “Donna Lee” was almost certainly hearing it get butchered by Phish. Still, I have to give them credit for introducing bebop to a wider audience. One of my main motivations for learning to read music as a college student was so I could play “Donna Lee” out of the Real Book. I succeeded, eventually, but it took an incredibly long time, and I wasn’t able to flow through it steadily until many years later.

RIP Godfried Toussaint

I was sad to learn about the recent death of Godfried Toussaint, whose work on the geometry of musical rhythm has been a major inspiration for me.

Godfried Toussaint

I never met Godfried, but I have read and re-read his work. His rhythm necklace diagrams were the direct inspiration for the Groove Pizza – I saw them and thought, I would love to have a drum programming interface like that.

I Wanna Dance With Somebody

I was looking for some new acapellas to remix, and was delighted to come across Whitney Houston’s vocal stem from “I Wanna Dance With Somebody (Who Loves Me).” The 808-cowbell-laden production has undeniable charm, but the vocals by themselves are the real truth.

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 halfway between G and G-sharp. Modulating there is a bananas thing to do!
