We created the Groove Pizza to make it easier to both see and hear rhythms. The next step is to create learning experiences around it. In this post, I’ll use the Pizza to explain the structure of some quintessential funk and hip-hop beats. You can click each one in the Groove Pizza, where you can customize or alter it as you see fit. I’ve also included Noteflight transcriptions of the beats.

This simple pattern is the basis of just about all rock and roll: kicks on beats one and three (north and south), and snares on beats two and four (east and west.) It’s boring, but it’s a solid foundation that you can build more musical-sounding grooves on top of.

This Billy Squier classic is Number nine on WhoSampled’s list of Top Ten Most Sampled Breakbeats. There are only two embellishments to the backbeat cross: the snare drum hit to the east is anticipated by a kick a sixteenth note (one slice) earlier, and the kick drum to the south is anticipated by a kick an eighth note (two slices) earlier. It isn’t much, but together with some light swing, it’s enough to make for a compelling rhythm. The groove is interestingly close to being symmetrical on the right side of the circle, and there’s an antisymmetry with the kick-free left side. That balance between symmetry and asymmetry is what makes for satisfying music. Continue reading
The first song on Kanye West’s Life Of Pablo album, and my favorite so far, is the beautiful, gospel-saturated “Ultralight Beam.” Say what you want about Kanye as a public figure, but as a musician, he is in complete control of his craft. See a live performance on SNL.
The song uses only four chords, but they’re an interesting four: C minor, E-flat major, A-flat major, and G7. To find out why they sound so good together, let’s do a little music theory.
The MusEDLab and Soundfly just launched Theory For Producers, an interactive music theory course. The centerpiece of the interactive component is a MusEDLab tool called the aQWERTYon. You can try it by clicking the image below. (You need to use Chrome.)
In this post, I’ll talk about why and how we developed the aQWERTYon.
I’m a proud member of the NYU Music Experience Design Lab, a research group that crosses the disciplines of music education, technology, and design. Here’s an overview of our many ongoing projects.
Linear music notation is good for reading, but it doesn’t tell you everything you want to know about underlying musical structure. Notes that are close to each vertically are not necessarily the most closely related. The concept of harmonic relatedness is a complex one, but there’s an excellent tool for beginning to get a handle on it: the circle of fifths.
The left circle above shows the chromatic circle, the pitch sequence you find on the piano. The right circle shows the circle of fifths. Each note is a fifth higher or a fourth lower than its counterclockwise neighbor, and each note is also a fourth higher or a fifth lower than its clockwise neighbor.
Unlike a lot of music theory you learn in school, the circle of fifths is not some arbitrary Western European cultural convention. There’s actual science behind it. If two notes are adjacent on the circle of fifths, it means they have a lot of overtones in common. If you know what overtones are, you can skip the next few paragraphs. Otherwise, read on.
The folks at Olympia Noise Co recently came out with a new circular drum machine for iOS called Patterning, and it’s pretty fabulous.
The app’s futuristic look jumps right out at you: flat-colored geometric shapes with zero adornment, in the spirit of Propellerhead Figure. There’s nothing on the screen that doesn’t function in some way. It’s a little dense at first glance, but a complex tool is bound to have a complex interface, and Patterning reveals itself easily through exploration.
I’m part of a research group at NYU called the Music Experience Design Lab. One of our projects is called Play With Your Music, a series of online interactive music courses. We’re currently developing the latest iteration, called Play With Your Music: Theory. Each module presents a “musical simple,” a short and memorable loop of melody or rhythm. Each simple is a window into one or more music theory concepts. Users can learn and play with the simples using a new interface called the aQWERTYon, which maps scales and chords to the regular computer keyboard.
The simplest and most effective optical illusion ever is the Necker cube. Which side is in front? The answer is both and neither. Very Zen.
In the process of gathering musical simples, I found a P-Funk loop with a similar effect. It’s a keyboard lick from “Do That Stuff” from The Clones Of Dr Funkenstein.
I have a whole lot of explanatory writing about rhythm in the pipeline, and thought it would be good to have a place to link the word “syncopation” to every time it arises. So here we go. Syncopation is to rhythm what dissonance is to harmony. A syncopated rhythm has accents on unexpected beats. In Western classical music, syncopation is usually temporary and eventually “resolves” to simpler rhythms. In the music of the African diaspora, syncopation is a constant, in the same way that unresolved tritones are constant in the blues.
Syncopation is not just a subjective quality of music; you can mathematically define it. Before we do, it helps to visualization a measure of 4/4 time, the amount of time it takes to count “one, two, three, four.”
The more times you have to subdivide the measure to get to a given beat, the weaker that beat is. When you accent weak beats, you get syncopation. Continue reading
