Identifying added-note chords

My NYU aural skills students are working on chord identification. My last post talked about seventh chords; this post is about chords with more notes in them, or at least, different notes. My theory colleagues call them added-note chords. They are more commonly called jazz chords, though many of the examples I list below are not from jazz. You could also call them extended chords, or complicated chords, or fancy chords, or cool chords. It’s easy to get overwhelmed by all the numbers and symbols. My preferred way to organize all this information is to think of chords as vertically stacked scales. It is intimidating to try to learn to distinguish between C7, C9, C13, C7sus4, C9sus4 and C13sus4, but they are really just different combinations of the notes in C Mixolydian mode, and they all convey a similar “Mixolydian-ness”. But before we get to those, let’s start with extended chords you can make from regular old C major.

I made a new track for teaching swing

I just finished my Groove Theories book proposal and sent it out, that was about twenty years of very slow work followed by two weeks of very fast work. So fingers crossed on that. I included two sample chapters, one on blues tonality, and one on swing. For the swing chapter, I wanted to find examples of the same piece of music played with and without swing for ease of comparison. In class, I usually play “Dance of the Sugar Plum Fairy” from the Nutcracker Suite and “Sugar Rum Cherry” by Duke Ellington. This isn’t an exact comparison, though, because Ellington does more than change the time feel; he also changes the instrumentation and structure. I wanted to find an example where the same music repeated identically with and without swing. The problem is that so far as I can tell, no such piece of music exists. But then I realized that it would be easy to make this piece of music myself, by warping something out in Ableton Live and applying different groove settings.

The twelve bar blues

This week in the Song Factory, we begin talking about the conventions of the blues. One central convention is the twelve-bar form. It’s so closely associated with the blues generally that jazz musicians use the term “a blues” to mean any tune using the twelve-bar form. However, it is surprisingly difficult to define what the twelve-bar blues actually is. That’s because there is no such thing as “the” twelve bar blues. Instead, there is a vast constellation of blues song forms that share some general structural features in common. In this post, I won’t even begin to list every variant; I’ll just give some representative examples. For the real truth about this music, you need to consult the music itself.

The Song Factory course

I have been teaching songwriting for a lot of years as a means to other ends: with my private guitar and production students, with my music tech students, with my music education students, with my music theory students. But this semester at The New School, I get to teach my first actual songwriting class whose only goal is to be a songwriting class. It’s called The Song Factory. I didn’t choose the name, but I like it.

The class is meant to both be a songwriting workshop and a survey of American popular song. My plan is to do six units. For each unit, the class will do some listening, reading and discussion, and then they will write an original song. I am requiring that these songs have lyrics, and the students must sing/rap them in class. I am not particular about how they accompany their vocals. They can play their instruments, record their own backing tracks, or use existing loops, instrumentals, type beats or karaoke tracks. We will talk about composition, arrangement and production a bit, but we will mainly be concerned with the sung/rapped aspect of songwriting.

The microphone placement playlist

Last week in music tech class, we talked about audio recording, and how the placement of microphones relative to the voices or instruments can shape the sound of a recording. Mics don’t just pick up the sound of the voice or instrument itself. They also pick up the sound of the voice or instrument bouncing off the walls, floor, and ceiling. Depending on where the mic is relative to the sound source, it might pick up more direct sound or more indirect sound. The specific blend tells the listener a lot about the environment that the sound was recorded in, and carries information about style and genre too. 

Here’s a highly simplified diagram of sound in an environment. The solid line represents direct sound, pressure waves going straight from the guitar into your ear. The dotted lines are indirect sound, pressure waves that bounce off the walls, floor and ceiling before reaching your ear.

In a recording, microphones are a stand-in for your ears, receiving pressure waves and converting them into electrical fluctuations. If the mic is close to the sound source, it will mostly pick up direct sound. If the mic is far away from the sound source, it will mostly pick up indirect sound.

The first day of Contemporary Music Theories at the New School

Here are the tracks we listened to on the first day of Contemporary Music Theories at the New School. The class is a requirement for music majors, and as its name suggests, it is intended to give a broad-based understanding of music theory, not just Western tonal theory. We started things off with excerpts of the Chaconne from the Violin Partita No. 2 in D minor by Johann Sebastian Bach, composed in or near 1720, performed by the guitarist Christopher Parkening.

The Kronos Quartet play Jimi Hendrix

I have mixed feelings about the Kronos Quartet arrangement of “Purple Haze” by Jimi Hendrix. On the one hand, it’s cool that they even attempted it. On the other hand, is the attempt successful?

It’s great that they’re taking advantage of the violin’s pitch continuum to do all the blue notes and guitaristic bends and slides and such. I’d love to hear more of that in string quartet writing. Continue reading

I was weirdly obsessed with this jazz tune when I was twelve

I mainly grew up in a classical radio type of household, but my folks had a couple of jazz albums too, including Duke’s Memories by Abdullah Ibrahim. It included an obscure Ellington tune called “Way Way Back.”

The melody is elegantly simple, and reveals greater depth with each listen. When I was in sixth grade, I was obsessed with this track. I listened to it over and over and over. I liked to sit and draw abstract geometric shapes and cartoon beings while I listened. I had no idea where to take this interest until years later. Evidently I had good taste as a kid! The tune is a great one, and the recording is deep in the pocket. I don’t love that 80s rubber-band-like upright bass pickup sound, but the groove is impeccable.

Swing primer

It don’t mean a thing if it ain’t got that swing, doo-wah doo-wah doo-wah doo-wah doo-wah doo-wah doo-wah doo-wah” – Duke Ellington

Hear a seamless collage of several varieties of swing:

Aside from the blues, swing is the United States’ most significant musical innovation. People typically associate its rubbery, sensual feel with jazz, but swing is everywhere in the musics descended from the African diaspora: ragtime, blues, musical theater, country, R&B, rock, funk, reggae, hip-hop, electronic dance music, and so on. The best way to learn about swing is through aural and hands-on experience. The Groove Pizza is a good way to get started.

Songs vs Grooves

Anne Danielsen’s book Presence and Pleasure: The Funk Grooves of James Brown and Parliament is one of my favorite works of musicology. In the book, Danielsen distinguishes between songs and grooves.Yesterday” by the Beatles is a song. “The Payback” by James Brown is a groove.

In structural terms, a groove is a small musical cell that repeats indefinitely. A song is a hierarchical organization of smaller cells that form a linear sequence with a beginning, middle and end. The lack of large-scale structure in a groove makes it effortlessly malleable and extensible. Want to make it thirty seconds longer? No problem. Want to make it thirty minutes longer? No problem. Songs are not so flexible. If you wanted to make “Yesterday” longer, would you… make up more verses? Repeat the bridge again?
