Identifying standard pop chord progressions

This week in aural skills, we are practicing identifying pop schemas, that is, chord sequences and loops that occur commonly in various kinds of Anglo-American top 40, rock, R&B and related styles. We previously covered the permutations of I, IV and V and the plagal cadence. Now we’re getting into progressions that bring in the rest of the diatonic family, that is, the chords you can make using the notes in the major and natural minor scales.

Singer-Songwriter/Axis progression

A huge percentage of current mainstream pop and rock songs are built on the four-legged stool of the I, IV, V and vi chords. In C, those are C, F, G, and Am. You can find these chords in any order, but there’s a particularly inescapable sequence that my NYU colleagues call the singer-songwriter progression: I, V, vi, IV, which in C is C, G, Am, F.

Did Lorde rip off George Michael?

Lorde has a new song. If you are a George Michael fan, parts of it will sound very familiar!

The guitar part in the first verse is strongly reminiscent of the one in “Faith.”

But people seem to be mainly worked up about the similarities in the overall rhythmic groove and chord changes to the ones in “Freedom ’90.”

Let’s unpack!

Groove harmony

See also a study of groove melody

Chords work differently in grooves than they do in songs and linear compositions. In his book Everyday Tonality, Philip Tagg proposes that chords in loops are mainly there to signpost locations in the meter. By his theory, the metrical location of a chord matters more than its harmonic function. This idea aligns with my experience of listening to and making groove-based music. I’d like to develop it further, to form a general theory of how groove harmony works.

I don’t plan to try to explain every kind of groove there is, but I do want to look for widely recurring patterns. My main goal is to save my students the many years of trial and error that it took me to figure out this vast and understudied area of musical practice.

Disclaimers: this isn’t any kind of complete theory, it’s me thinking out loud about a bunch of examples. I chose those examples because I like them and find them interesting, not because I’m trying to be systematic.

Brian Eno and the role of the producer

The meaning of the word “producer” has changed significantly over the history of recorded music. Before the 1960s, most record producers were businesspeople, responsible for signing checks and making sure the musicians and engineers did their jobs. Some producers took a creative role in choosing repertoire, arrangements and takes, but others were hands-off. As recording technologies and processes became more complex and further removed from documenting real-time performances, producers started to take on more creative importance. Consider George Martin’s role with the Beatles. For the first few albums, he simply supervised the recording process, but as time went on, he began to write and conduct orchestral arrangements, play instruments, and carry out technical experiments with the band and engineers.

In the 1970s, more artists started to think of the recording studio itself as an instrument, assembling tracks into collages that sometimes bore little resemblance to the original live performances. An album like Pink Floyd’s Dark Side of the Moon was as much a creation of the producers and engineers as the songwriters and musicians. As they started “playing the studio,” album producers became less like film producers and more like film directors. (Meanwhile, recorded music became less like filmed stage plays and more like Pixar or Star Wars movies.)

Brian Eno is a crucial figure in this evolution. It’s significant that his background is in visual art, not music. (Many British rock and pop musicians got started in art school.) Eno has described himself as a “non-musician.” He initially thought of himself as a conceptual artist more than anything. As a student, he experimented with electronic music under the influence of John Cage and Karlheinz Stockhausen, but he approached these projects as sound art, not as “music” necessarily.

Prepping my rap and rock class at Montclair State

This summer, I’m teaching Cultural Significance of Rap and Rock at Montclair State University. It’s my first time teaching it, and it’s also the first time anyone has taught it completely online. The course is cross-listed under music and African-American studies. Here’s a draft of my syllabus, omitting details of the grading and such. I welcome your questions, comments and criticism.

Musical simples

The NYU Music Experience Design Lab is putting together a new online music theory resource, and I’m writing a lot of the materials. We want to keep everything grounded in real-life musical practice. To that end, we’ve been gathering musical simples: phrases, riffs, and earworms that beginners can learn easily. My criteria for a good musical simple: It should be a piece of music that can stand on its own, and that makes a satisfying loop. It should be catchy, attractive, and (ideally) already familiar. And it should be between one and four measures long. We’re developing a web-based interface that will make it easy to learn a musical simple, play it back, and mutate and adapt it. Each theory concept will come with at least one simple to give it authentic cultural context.

It’s an axiom of constructivism that you learn best when you’re enjoying yourself. This might seem obvious, but it represents a break with music education orthodoxy. Music students too often have to do a lot of tedious drilling before they get to try some real music. Even then, those tunes tend to be nursery rhymes or dorky educational pieces. It makes a certain amount of sense to structure lessons this way: real music is complicated and usually well out of reach of beginners. Unfortunately, too many beginners give up before they make it past the nursery rhyme stage.

Beginner-level music teaching nearly always starts at the atomic level: single pitches, note values, time signatures. It seems logical that the smallest units of music would be the simplest ones. But this is not actually true. Beginners conceive of music at a more intermediate level of abstraction: fragments of tunes, moments of tension and resolution, loops and grooves. Self-taught and informally taught musicians do most of their learning at this level. A three-chord song by Bob Marley or Neil Young is a better entry point than the single notes comprising those three chords and the relationship between them.

Here’s a diagram from my masters thesis, adapted from a paper by Jeanne Bamberger:

Moving up and down the structural ladder

For more discussion of these ideas, see also Bamberger’s “Developing Musical Structures: Going Beyond The Simples.”

It’s hard to resist the temptation to start at the bottom of the abstraction ladder. Even though I’m a self-taught pop musician, I still instinctively “start at the beginning” whenever I set out to explain something to a student, and have to consciously remind myself to find a mid-level explanation first. I try to think in terms of chemistry. Atoms and their component particles are “simpler” than molecules and complex substances. But most of us don’t have direct experience with atoms. We’re familiar with water and air and rocks and metals. We need to think about water before we can understand hydrogen and oxygen. So it is with music. The musical simples are our molecules and substances, mid-level entry points that scaffold learning of atoms and electrons.

I was unconsciously gathering musical simples long before I heard the term. I was looking for stuff that’s easy to learn, but that’s also substantive enough to work as real music. The good news is that there’s plenty of simple music that isn’t lame. The music of the African diaspora is built on riffs and loops, and jazz and rock and pop are full of easy yet richly satisfying musical ideas. By carefully curating a simples collection, we’re hoping to make life easier for anyone who wants to teach or learn music in an engaging and pleasurable way. Here’s an assortment, shown both in standard notation and MIDI piano roll format. Continue reading
