Blues tonality

See a more beginner-friendly blues primer here. Read this treatise in Spanish, translated by Jesús Fernández.

Abstract

The blues is a foundational element of America’s vernacular and art music. It is commonly described as a combination of African rhythms and European harmonies. This description is inaccurate. Blues follows harmonic conventions that are quite different from those of Western European common practice. Blues harmony does not fit into major or minor tonality, and it frequently violates the “rules” of voice leading and chord function. But blues listeners do not experience the music as strange or dissonant. Instead, they hear an alternative form of consonance. In order to make sense of this fact, we need to understand blues as belonging to its own system of tonality, distinct from major, minor and modal systems. Because blues tonality is so widespread and important in Western music, I argue that we should teach it as part of the basic music theory curriculum. Continue reading “Blues tonality”

Digital audio basics

Before you can understand how digital audio works, you need to know a few things about the physics of sound. This animation shows a sound wave emanating through the air from a circular source — imagine that it’s a drum or cymbal.

Spherical pressure waves

As you can see, sound is a wave, like a ripple in a pond. Imagine that your ear is at the bottom center of this image. The air pressure against your inner ear is rhythmically increasing and decreasing. Your brain senses how wide those swings in air pressure are and how often they’re happening, and you experience the result as a sound.

My music education

I’m writing a chapter of the forthcoming Oxford Handbook of Technology and Music Education. Here’s a section of what I wrote, about my own music learning experiences.

Most of my music education has happened outside of the classroom. It has come about intentionally, through lessons and disciplined practice, and it has come about unintentionally, through osmosis or accidental discovery. There has been no separation between my creative practice, my learning, and my teaching.

My formal music education has been a mixed bag. In elementary school, I did garden-variety general music, with recorders and diatonic xylophones. I don’t remember enjoying or not enjoying it in particular. I engaged more deeply with the music my family listened to at home: classical and jazz on public radio; the Beatles, Paul Simon and Motown otherwise. Like every member of my age cohort, I listened to a lot of Michael Jackson, and because I grew up in New York City, I absorbed some hip-hop as well.

In middle school we started on traditional classical music. I chose the cello, for no good reason except that I had braces and so was steered away from wind instruments. I liked the instrument, and still do, but the cello parts in basic-level Baroque music are mostly sawing away at quarter notes, and I lost interest quickly. Singing showtunes in chorus didn’t hold much appeal for me either, and I abandoned formal music as soon as I was able.

Sucker MCs

Sasha Frere-Jones was recently asked by The Guardian to make a list of perfect songs. I don’t agree with all of his choices — Taylor Swift? — but I can definitely get behind his nomination of “Sucker MCs” by Run-DMC.

This track was the B-side to Run-DMC’s first single in 1983, and was produced by Larry Smith and Davy DMX of Orange Krush (thus the subtitle “Krush Groove 1.”) It’s beautiful in its simplicity: two guys rapping, an Oberheim DMX drum machine, some turntable scratching, and nothing else. It’s the most minimalist hip-hop song I know of, other than “Top Billin’” by Audio Two.

Remix as compositional critique

This month I’ve been teaching music production and composition as part of NYU’s IMPACT program. A participant named Michelle asked me to critique some of her original compositions. I immediately said yes, and then immediately wondered how I was actually going to do it. I always want to evaluate music on its own terms, and to do that, I need to know what the terms are. I barely know Michelle. I’ve heard her play a little classical piano and know that she’s quite good, but beyond that, I don’t know her musical culture or intentions or style. Furthermore, she’s from China, and her English is limited.

I asked Michelle to email me audio files, and also MIDI files if she had them. Then I had an epiphany: I could just remix her MIDIs, and give my critique totally non-verbally.

The great music interface metaphor shift

I’m working on a long paper right now with my colleague at Montclair State University, Adam Bell. (Update: here’s the paper.) The premise is this: In the past, metaphors came from hardware, which software emulated. In the future, metaphors will come from software, which hardware will emulate.

The first generation of digital audio workstations have taken their metaphors from multitrack tape, the mixing desk, keyboards, analog synths, printed scores, and so on. Even the purely digital audio waveforms and MIDI clips behave like segments of tape. Sometimes the metaphors are graphically abstracted, as they are in Pro Tools. Sometimes the graphics are more literal, as in Logic. Propellerhead Reason is the most skeuomorphic software of them all. The main image from the Propellerhead web site makes the intent of the designers crystal clear; the original analog synths dominate the image.

In Ableton Live, by contrast, hardware follows software. The metaphor behind Ableton’s Session View is a spreadsheet. Many of the instruments and effects have no hardware predecessor.

A DIY video about DIY recording

For the benefit of Play With Your Music participants and anyone else we end up teaching basic audio production to, MusEDLab intern Robin Chakrabarti and I created this video on recording audio in less-than-ideal environments.

This video is itself quite a DIY production, shot and edited in less than twenty-four hours, with minimal discussion beforehand and zero rehearsal. Continue reading “A DIY video about DIY recording”

Killen and Marotta

Participants in Play With Your Music were recently treated to an in-depth interview with two Peter Gabriel collaborators, engineer Kevin Killen and drummer Jerry Marotta. Both are highly accomplished music pros with a staggering breadth of experience between them. You can watch the interview here:

Kevin Killen engineered So and several subsequent Peter Gabriel albums. His other engineering and mixing credits include Suzanne Vega, Gilbert O’Sullivan, Bobby McFerrin, Elvis Costello, Dar Williams, Sophie B. Hawkins, Ricky Martin, Madeleine Peyroux, U2, Allen Toussaint, Duncan Sheik, Bob Dylan, Ennio Morricone, Tori Amos, Rosanne Cash, Shakira, Talking Heads, John Scofield, Anoushka Shankar, Patti Smith, Laurie Anderson, Stevie Nicks, Los Lobos, Kate Bush, Roy Orbison and Bryan Ferry.

Kevin Killen

Jerry Marotta played drums on all of Peter Gabriel’s classic solo albums. He has also performed and recorded with a variety of other artists, including Hall & Oates, the Indigo Girls, Ani DiFranco, Sarah McLachlan, Marshall Crenshaw, Suzanne Vega, John Mayer, Iggy Pop, Tears for Fears, Elvis Costello, Cher, Paul McCartney, Carly Simon, and Ron Sexsmith.

Jerry Marotta

The interview was conducted by NYU professor and Play With Your Music lead designer Alex Ruthmann and UMass Lowell professor Alex Case. Here’s an edited summary. Continue reading “Killen and Marotta”

Internet blues

Recently, WNYC’s great music show Soundcheck held a contest to see who could do the best version of the 100 year old song “Yellow Dog Blues” by WC Handy.

Marc Weidenbaum had the members of the Disquiet Junto enter the contest en masse. I did my track, put it on SoundCloud, and promptly forgot all about it.

A month later, I was surprised and delighted to learn from Marc’s blog that the contest winner was Junto stalwart Westy Reflector.
