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, …

The vocoder and Auto-Tune

The vocoder is one of those mysterious technologies that’s far more widely used than understood. Here I explain what it is, how it works, and why you should care. Casual music listeners know the vocoder best as a way to make the robot voice effect that Daft Punk uses all the time. Here’s Huston Singletary …

QWERTYBeats design documentation

QWERTYBeats is a proposed accessible, beginner-friendly rhythm performance tool with a basic built-in sampler. By simply holding down different combinations of keys on a standard computer keyboard, users can play complex syncopations and polyrhythms. If the app is synced to the tempo of a DAW or other music playback system, the user can easily perform good-sounding …

Scale necklaces and symmetry

While I was doing some examination of rhythm necklaces and scale necklaces, I noticed a symmetry among the major scale modes: Lydian mode and Locrian mode are mirror images of each other. Does this geometric relationship mean anything musically? Turns out that it does. Lydian and Locrian are mirror images in feeling, not just as …

Fractal music

Continuing my series of posts on the ways that science might explain why we like the music we like. See also my posts on the science of rock harmony, harmony generally, and Afro-Cuban rhythms. Quora user Marc Ettlinger recently sent me a paper by Sherri Novis-Livengood, Richard White, and Patrick CM Wong entitled Fractal complexity …

Why is son clave so awesome?

One of the best discoveries I made while researching the Groove Pizza is the mathematician Godfried Toussaint. While the bookshelves groan with mathematical analyses of Western harmony, Toussaint is the rare scholar who uses the same tools to understand Afro-Cuban rhythms. He’s especially interested in the rhythm known to Latin musicians as 3-2 son clave, …

Can science make a better music theory?

My last post discussed how we should be deriving music theory from empirical observation of what people like using ethnomusicology. Another good strategy would be to derive music theory from observation of what’s going on between our ears. Daniel Shawcross Wilkerson has attempted just that in his essay, Harmony Explained: Progress Towards A Scientific Theory …

Teaching math with the Drum Loop

I’ve undergone some evolution in my thinking about the intended audience for my thesis app. My original idea was to aim it at the general public. But the general public is maybe not quite so obsessed with breakbeats as I am. Then I started working with Alex Ruthmann, and he got me thinking about the …

What is an octave?

Octaves are notes that you hear as being “the same” in spite of their being higher or lower in actual pitch. (Technically, notes separated by an octave are in the same pitch class.) Play middle C on the piano. Then go up the C major scale (the white keys) and the eighth note you play …
