Announcing the Theory aQWERTYon

A few years ago, the NYU Music Experience Design Lab launched a web application called the aQWERTYon. The name is short for “QWERTY accordion.” The idea is to make it as easy to play music on the computer keyboard as it is with the chord buttons on an accordion. The aQWERTYon maps scales to the …

Jacob Collier’s four magical chords

Jacob Collier is the internet’s favorite musical virtuoso. Here’s his mostly acapella arrangement of a Christmas carol called “In The Bleak Midwinter.” The most remarkable part of this arrangement comes between the third and fourth verses, when Collier modulates from the key of E to the key of G half-sharp. That’s the key which is …

Naima

I’ve been doing so much explaining basic music theory that I thought it would be fun to dig into something advanced: “Naima” by John Coltrane, from his all-killer-no-filler album Giant Steps. There are as many interpretations of this tune’s chord changes as there are transcriptions of it. The ones in the Real Book are real …

Developing an intro-level music theory course

In the fall of 2019, I started teaching Fundamentals of Western Music at the New School’s Eugene Lang College. It combines the usual Music Theory I content with a broader, more ethnomusicological perspective that brings in various forms of pop, non-Western musics, and (most excitingly for me) the blues. It’s an existing course, but I …

The Groove Pizzeria

For his NYU music technology masters thesis, Tyler Bisson created a web app called Groove Pizzeria, a polyrhythmic/polymetric extension of the Groove Pizza. Click the image to try it for yourself.  Note that the Groove Pizzeria is still a prototype, and it doesn’t yet have the full feature set that the Groove Pizza does. …

Why can’t you tune your guitar?

Short answer: because math. Longer answer: because prime numbers don’t divide into each other evenly. To understand what follows, you need to know some facts about the physics of vibrating strings: When you pluck a guitar string, it vibrates to and fro. You can tell how fast the string is vibrating by listening to the …

The “Rockit” rhizome

I have come to believe that Herbie Hancock’s “Rockit” is the most interesting musical recording of all time. It touches every form of twentieth century American music, from blues to jazz to rock to techno, and it’s one of the founding documents of global hip-hop. Not bad for a last-ditch effort to keep Herbie’s label …

Samuel Halligan’s awesome Pop-Up Piano for Ableton Live

I recently met a gentleman named Samuel Halligan, who, among other things, makes music education utilities using Max For Live. One of them is called Pop-Up Piano. If you use Max or Ableton and you could use some help learning music theory, you should go and download it immediately. It’s a Max For Live Device …

Future jazz

In my recent post about “Giant Steps,” I briefly mentioned the idea of doing improvisational remixes of jazz recordings. This is a big enough idea to merit a post of it own. My slow-tempo remix of the tune includes a solo section that I played by slicing up the melody, putting each note on a sample pad, …

Giant Steps

This Vox explainer video about John Coltrane’s most iconic tune is making the rounds right now. It’s well made and engaging. You should watch it! “Giant Steps” is a beautiful tune, one that rewards as much scrutiny as you care to give it. But it also had some negative effects on jazz as an art …
