The happiest chord progression ever

If you’re interested in learning more about chords and emotions, take my online course.

See also the saddest chord progression ever.

We think of descending melodies and chord progressions as being sad. But the happiest song of all time also has a descending progression: “I Want You Back” by the Jackson 5.

This recording was made just after Michael’s eleventh birthday. I do not approve of child labor, and making a prepubescent boy sing all these songs about romantic love ended up having some grim long-term psychological consequences. But god, what a performance.

The fake and the real in Chance the Rapper’s “All We Got”

Every semester in Intro to Music Tech, we have Kanye West Day, when we listen analytically to some of Ye’s most sonically adventurous tracks (there are many to choose from.) The past few semesters, Kanye West Day has centered on “Ultralight Beam,” especially Chance The Rapper’s devastating verse. That has naturally led to a look at Chance’s “All We Got.”

All the themes of the class are here: the creative process in the studio, “fake” versus “real” sounds, structure versus improvisation, predictability versus surprise, and the way that soundscape and groove do much more expressive work than melody or harmony.

Four bars of Mozart explains everything humans like in music

I’m not arguing here that everyone loves Mozart, or that I’m about to explain what all humans enjoy all the time. But I can say with confidence that this little bit of Mozart goes a long way toward explaining what most humans enjoy most of the time. The four bars I’m talking about are these, from “Eine Kleine Nachtmusik.”

What these four bars of music demonstrate is that humans like:

  1. Repetition
  2. Breaks in the repetition
  3. Repetition of the breaks in the repetition
  4. Breaks in the repetition of the breaks in the repetition
  5. Recursive layers of patterns of breaks and repetitions

In order to prove this to you, I’m going to talk you through these eighteen notes one at a time.

The Vocoder, Auto-Tune, Pitch Standardization and Vocal Virtuosity

Writing assignment for History of Science and Technology class with Myles Jackson. See a more informal introduction to the vocoder here.

Casual music listeners know the vocoder best as the robotic voice effect popular in disco and early hip-hop. Anyone who has heard pop music of the last two decades has heard Auto-Tune. The two effects are frequently mistaken for one another, and for good reason—they share the same mathematical and technological basis. Auto-Tune has become ubiquitous in recording studios, in two very different incarnations. There is its intended use, as an expedient way to correct out-of-tune notes, replacing various tedious and labor-intensive manual methods. Pop, hip-hop and electronic dance music producers have also found an unintended use for Auto-Tune, as a special effect that quantizes pitches to a conspicuously excessive degree, giving the voice a synthetic, otherworldly quality. In this paper, I discuss the history of the vocoder and Auto-Tune, in the context of broader efforts to use science and technology to mathematically analyze and standardize music. I also explore how such technologies problematize our ideas of virtuosity.

The aQWERTYon pitch wheels and the future of music theory visualization

Try a very early alpha of the scale wheel visualization here

The MusEDLab will soon be launching a revamped version of the aQWERTYon with some enhancements to its visual design, including a new scale picker. Beyond our desire to make our stuff look cooler, the scale picker represents a challenge that we’ve struggled with since the earliest days of aQW development. On the one hand, we want to offer users a wide variety of intriguing and exotic scales to play with. On the other hand, our audience of beginner and intermediate musicians is likely to be horrified by a list of terms like “Lydian dominant mode.” I recently had the idea to represent all the scales as colorful icons, like so:

Read more about the rationale and process behind this change here. In this post, I’ll explain what the icons mean, and how they can someday become the basis for a set of new interactive music theory visualizations.

Toward a Methodological Stance

Final paper for Approaches To Qualitative Inquiry with Colleen Larson

Section 1: Reflections on Received View of Research

I was raised by two medical researchers and a former astrophysicist, surrounded by stacks of quantitative journals. I rarely questioned the assumption that quantitative empirical research is the gold standard of truth, and that while subjective accounts are interesting and illuminating, they are not ultimately reliable. From scientists I learned that stories belong to mythology, while facts do not necessarily organize themselves in ways that can be apprehended so easily. Creation myths tell the story of a human-scale world in which humans are the most important element. Astrophysicists tell us that the universe is unfathomably vast and incomprehensibly old, and that we are insignificant in the grand scheme of things, while evolution teaches that we are more like mushrooms or daisies than unlike them. It is axiomatic for scientists that reality is empirically knowable, and while social and emotional considerations are a fact of life, they are noise to be filtered out.
