I’m continuing to gather materials for my upcoming ISMIR 2016 presentation on Why Hip-Hop Is Interesting. One of my big themes is the melodic content of rap. Emcees are deliberate in their use of pitch, whether they’re singing or rapping or some combination of the two. In the post, I’ll analyze segments of three great emcees’ flow. I made the graphics by loading acapella tracks into Melodyne, and then added the lyric annotations by hand using Omnigraffle. The selection of these tracks represents the intersection of “songs that I like” and “acapellas that are available to me.”
Eric B and Rakim – “Follow The Leader”
Emcee: Rakim Allah
Rakim Allah stands out among eighties rappers for the complexity and subtlety of his flow. Here’s an excerpt from verse one:
In a previous post, I used the Groove Pizza to visualize some classic hip-hop beats. But the kids are all about trap beats right now, which work differently from the funk-based boom-bap of my era.
The same Disquiet Junto project that spawned this wildly recursive remix also involved a few more people remixing my remix. Here’s a family tree of the three first generation source tracks, the seven second generation remixes of those tracks, and the three third generation remixes of the second generation remixes.
You can hear the three third-generation metaremixes below.
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.
