How to tell funk from disco

Here’s a short excerpt from my blues tonality paper that I thought would stand alone well on its own.

How do we decide that a song is rock, or folk, or country, or country-rock, or folk-rock? Nearly all American popular and vernacular is informed by blues. We can use this fact to help delineate overlapping and vaguely defined genre boundaries. Just as we can explain genre in terms of characteristic rhythms and timbres, so too can we explain it in terms of the amount of blues harmony present. Good pop and jazz practitioners already do this implicitly. A guitarist or singer needs a sense of how much blues tonality to use in order to sound more characteristically ‘jazzy’ or ‘country’ or ‘rock.’

Let’s use the example of funk. Aficionados like me know when music is funky. But how do we know? The most obvious characteristic to point to is the beat. But you can also hear funk rhythms in disco, hip-hop, R&B, rock, and even country — Dolly Parton’s “Jolene” is super funky. We can distinguish funk as a genre more specifically using its harmonic content. Funk is the most heavily blues-based genre aside from blues itself. While rock and country combine blues harmony with diatonicism, funk adds in jazz harmony instead.

Blues tonality

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 characterization is inaccurate. Blues follows harmonic conventions that are quite different from those of European common-practice tonality. Blues does not fit into major or minor tonality, and it makes heavy use of harmonic intervals considered by tonal theory to be dissonant. But blues listeners do not experienced the music as dissonant; rather, they hear an alternative system of consonance. In order to make sense of this system, we need to understand blues as belonging to its own tonality, distinct from major, minor and modal scales. The author argues that blues tonality should be taught as part of the basic music theory curriculum.

What is groove?

You hear musicians talk all the time about groove. You might wonder what they mean by that. A lot of musicians couldn’t explain exactly, beyond “the thing that makes music sound good.” The etymology of the term comes from vinyl records. Musicians ride the groove the way a phonograph needle physically rides the groove in the vinyl.

The original groove

But what is groove, exactly? It isn’t just a matter of everyone playing with accurate rhythm. When a classical musician executes a passage flawlessly, you don’t usually talk about their groove. Meanwhile, it’s possible for loosely executed music to have a groove to it. Most of my musician friends talk about groove as a feeling, a vibe, an ineffable emotional quality, and they’re right. But groove is something tangible, too, and even quantifiable.

Using digital audio production software, you can learn to understand the most mystical aspects of music in concrete terms. I’ve written previously about how electronic music quantifies the elusive concept of swing. Music software can similarly help you understand the even more elusive concept of groove. In music software, “groove” means something specific and technical: the degree to which a rhythm deviates from the straight metronomic grid. Continue reading

Composing improvisationally with Ableton Live

I just completed a batch of new music, which was improvised freely in the studio and then later shaped into structured tracks.

I thought it would be helpful to document the process behind this music, for a couple of reasons. First of all, I expect to be teaching this kind of production a lot more in the future. Second, knowing how the tracks were made might be helpful to you in enjoying them. Third, composing the music during or after recording rather than before has become the dominant pop production method, and I want to help my fellow highbrow musicians to get hip to it.

Tabla Breakbeat Science is dropping an album

My new studio band has an album nearing completion. It’s called Music Information Retrieval, because our studio time was sponsored by NYU’s Music and Audio Research Lab — we contributed to a database of multitracks that will be used for music informatics research.

We made our DJ debut over the weekend at the Rubin Museum, where our brand-new track “Rock Steady” was dropped by DJ Ripley.

Repetition defines music

Musical repetition has become a repeating theme of this blog. Seems appropriate, right? This post looks at a wonderful book by Elizabeth Hellmuth Margulis, called On Repeat: How Music Plays The Mind. It investigates the reasons why we love repetition in music. You can also read long excerpts at Aeon Magazine.

Here’s the nub of Margulis’ argument:

The simple act of repetition can serve as a quasi-magical agent of musicalisation. Instead of asking: ‘What is music?’ we might have an easier time asking: ‘What do we hear as music?’ And a remarkably large part of the answer appears to be: ‘I know it when I hear it again.’

Analyzing the musical structure of “Sledgehammer” by Peter Gabriel

We’re asking participants in Play With Your Music to create musical structure graphs of their favorite songs. These are diagrams showing the different sections of the song and where its component sounds enter and exit. In order to create these graphs, you have to listen to the song deeply and analytically, probably many times. It’s excellent ear training for the aspiring producer or songwriter. This post will talk you through a structure graph of “Sledgehammer” by Peter Gabriel. Co-produced by Peter and Daniel Lanois, this is an emblematic eighties pop tune.

Here are the video versions of my analysis:

Below is the musical structure graph. Click the image below to see it bigger, and with popup comments.

The backbeat: a literature review

This is part of a research project I’m doing for my Psychology of Music class at NYU, thus the formal tone.

Update: here’s the finished product.

The backbeat is a ubiquitous, almost defining feature of American popular and vernacular music. Clapping or snapping on the backbeats is generally considered by musicians to be more correct than doing so on the strong beats. However, audiences have a tendency to clap or snap on the wrong beats, to the irritation of the performers.

Friends don't let friends clap on one and three

On October 6th, 1993, the blues musician Taj Mahal gave a solo concert at the Modernes Club in Bremen, Germany. The concert was later released as the album An Evening of Acoustic Music. On the recording, Taj Mahal begins to play “Blues With A Feeling,” and the audience enthusiastically claps along. However, they do so on beats one and three, not two and four like they are supposed to. Taj immediately stops playing and says, “Wait, wait, wait. Wait wait. This is schvartze [black] music… zwei and fier, one TWO three FOUR, okay?” He resumes the song, and the audience continues to clap on the wrong beats. So he stops again. “No, no, no, no. Everybody’s like, ONE, two, THREE, no no no. Classical music, yes. Mozart, Chopin, okay? Tchaikovsky, right? Vladimir Horowitz. ONE two THREE. But schvartze music, one TWO three FOUR, okay?” He starts yet again, and finally the audience claps along correctly. To reinforce their rhythm, Taj Mahal continues to count “one TWO three FOUR” at various points during the song.
