Chord progressions in the Bach Chaconne

Recently I have been digging deep into the Bach Chaconne. Since I’m a poor music reader, I’ve been using Ableton Live to remix, loop, and analyze the piece, both in audio and MIDI form. It’s working! The structure of the Chaconne makes sense to me now when I hear it, and I’m learning to play sections of it (slowly and haltingly) on the guitar. I’m supposedly doing this because the piece is a useful teaching example for minor-key harmony. Really, though, I just enjoy listening to it and thinking about it, and I’m lucky enough to have a job where I can use some of that thinking later.

You’re supposed to analyze classical harmony by annotating the score with Roman numerals and figured bass. I come from jazz, though, and while we like Roman numerals in jazz, we don’t do figured bass. I did learn figured bass well enough to get through grad school, but I would rather write and think about modern chord symbols. Also, I’d much rather analyze by ear than on the page. So I went through the MIDI file of the Bach Chaconne and segmented it out whenever I heard a chord change. Then I labeled the chords, through a combination of looking at their constituent pitches and my subjective sense of the chords that those pitches imply.

My year in blogging

Two big things happened in my academic life this year: I wrote a dissertation proposal (which is not quite done yet), and I developed and taught a music theory course at the New School. Both of these projects featured heavily on this blog. Here are some high points.

Teaching dynamics and loudness

When I cover dynamics and loudness in music theory class, I only spend a small part of the time talking about forte/piano, crescendo/diminuendo and so on. Once you have the Italian translations, those terms are self-explanatory. They are also frustratingly subjective, and they refer only to unamplified acoustic music. To understand dynamics in the present day, you need to understand decibels, perceptual loudness, and what “dynamics” mean in the era of recorded, amplified and electronic music.

First of all, let’s talk about the classical terms a bit. When you see that classical music uses “piano” to mean “quiet,” you might naturally wonder what the relationship is to the instrument. The piano’s inventor, Bartolomeo Cristofori, originally called it “un cimbalo di cipresso di piano e forte,” meaning “a keyboard of cypress with soft and loud”. This got variously abbreviated as fortepiano, pianoforte, and finally, its current name. This was all in contrast to the piano’s predecessor, the harpsichord, which can only play at one volume.

Remixing Ben Shapiro

My dissertation research includes a methodology of my own invention, which I’m calling analytical remixing. I’m writing about three hip-hop educators, in order to illuminate hip-hop as an education philosophy, not just a subject area. That includes centering the remix as an important and underexplored music education practice. Beyond just writing about remixing, I am making some remixes as part of my research product. Specifically, I’m taking audio data (interviews, music, and various cultural artifacts) and remixing them to create a dissertation mixtape.

The value of the remix method is so self-evident to me that I made little effort to justify or explain it in the first draft of my dissertation proposal. However, my advisor, Alex Ruthmann, rightly pointed out that it is not self-evident to people who aren’t me. He suggestied that I pick a specific example and walk through it. So in this post, that’s what I’m going to do. It’s a remix I made of Ben Shapiro explaining why rap isn’t music.

How do key signatures work?

Most of my students struggle with key signatures. This is understandable! Like the rest of the Western notation system, key signatures are based on a big assumption: that all of the notes will be within one of the twelve major keys, or within some scale that can be derived from a major scale (most often, the natural minor scale). This assumption makes an awkward fit with the music that the kids are making and listening to. Read on!

Several students have asked me if there is some shortcut or mnemonic for memorizing the key signatures. The answer is, yes, there are many, but I’ve never found them to be helpful. The only thing that worked for me was to learn, write and improvise a lot of music in every major and minor key until they were as familiar as the layout of my apartment. My method was slow, but effective.

Live scoring with No Country for Old Men: update

This week in Fundamentals of Western Music class at the New School, we did an in-class improvisation exercise, where students created spur-of-the-moment scores to scenes from No Country for Old Men. I did this in response to being told by a faculty evaluator that I should have more music-making during class, a suggestion I strongly agree with. Students could choose between bringing their own instruments, playing synths from my computer, or using the piano in the classroom.

Live film scoring with No Country For Old Men

My New School class was recently observed by another faculty member. She suggested that I have the students do more music-making during class (currently they make lots of music, just outside of class.) I like this idea. So my plan is to do a live film scoring exercise using No Country For Old Men by the Coen Brothers. Each member of the class will improvise music along with a scene from the film. They can perform using instruments in Ableton or GarageBand via my little MIDI controller or the aQWERTYon. They can also use the piano in the classroom, or bring an instrument of their own. This is an improvisation exercise, and I am not expecting anyone to prepare. However, they are free to watch the movie first if they want.

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.
