Identifying song forms

Song structure is a strange music theory topic, because there is not much “theory” beyond just describing it. Why are some patterns of song sections so broadly appealing? The answer has something to do with the balancing of surprise and familiarity, of predictability and unpredictability, but if someone has a systematic theory of why some structures work so much better than others, I am not aware of it. The best approach I can recommend is to examine the most widely used structures across styles and eras and try to internalize them. Transcribing songs at the structural level is a great way to do that. Staff notation is not the right tool for the job, because you can’t easily zoom out and see the big picture. I like to use Ableton Live to annotate and color-code audio and MIDI. Here’s “Burning Down The House” by Talking Heads. 

I also like the bubble diagrams you can make with Audio Timeliner, because it lets you group sections together at multiple levels. The downside is that you can’t easily zoom into the bars and beats level, or show meter and hypermeter.

In this post, I’ll talk through examples of three common structures: strophic form, AABA form, and verse-chorus form (the one that “Burning Down The House” uses). Then I’ll get into the difficult question of form in groove-based music.

Identifying phrase structure

It’s easy to understand what a section of a song is: an intro, a verse, a chorus, a bridge. It is less easy to understand phrases, the components of a song section. Usually a song section contains between two and four phrases. But what is a phrase? No one seems totally sure. This is important to figure out, because if you aspire to write or improvise music, having control over your phrasing might be the most important thing you need. If you can organize your phrases, you can have limited technique and knowledge of theory and still sound good. If you can’t organize your phrases, all the technique and theory in the world won’t be much help.

Freedom Jazz Dance

A friend texted me to tell me that he was listening to a jazz show on public radio in Denver, and that they referenced an old blog post of mine about “Freedom Jazz Dance” by Eddie Harris. That was a pleasant surprise, and it made me want to go back to the post and freshen it up. So here are some new thoughts about what is arguably the weirdest jazz standard.

To be clear, there are many weirder jazz tunes than this, but not in the core repertoire. Also, “weird” does not mean “complex”. This tune is radical in its simplicity. In fact, it is so radically simple that usually when other people play it, they insert more structure into it. It illustrates the surprising fact that the simpler a tune is, the harder it can be for jazz musicians to improvise on it. We will get to this idea in more depth below.

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.

RIP Wayne Shorter

In 2013, Wayne Shorter said, “The word ‘jazz’ to me only means ‘I dare you.’” I love Wayne’s playing and writing without always understanding it. I got exposed to both via Miles Davis, who put Wayne’s tunes at the center of his late 1960s albums. Here’s “Orbits” from Miles Smiles.

And here’s an orchestral arrangement of the same tune recorded 36 years later on Wayne’s album Alegría. (It includes Brad Mehldau on piano.) Check out Wayne’s multiphonics at 1:55!

Where do jazz standards come from?

My Song Factory class is coming up on the Standards and Showtunes unit, covering the Great American Songbook. I mainly relate to these tunes via jazz.

There are numerous sources of jazz standards. In this post, I collect some of the ones that appear in movie musicals, and I pair each one with a well-known jazz interpretation. (Note that most of these had appeared in stage musicals many years earlier.) Enjoy! Continue reading

Dorian mode

Dorian mode is such a cool scale. It evokes medieval chant and the blues. Its characteristic minor sixth chord is almost a diminished chord. And it’s unique among the diatonic modes for being symmetrical, meaning that it uses the same sequence of intervals going up and down. When you write Dorian on the chromatic circle, it’s left-right symmetrical, and it’s even more obviously symmetrical on the circle of fifths.

Dorian mode is like a combination of the natural minor scale and Mixolydian mode. You can make Dorian by raising the sixth of natural minor, or by flatting the third of Mixolydian.

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.
