Ring the bells that still can ring

How did something as loud as a bell—something which is experienced so much more often, and more powerfully, by hearing than by sight—become dumb?

The sound of graph paper

GaMuSo is an application of BioGraph-based data mining to music, which helps you get recommendations for other musicians. Based on 140K user-defined tags from last.fm that are collected for over 400K artists, results are sorted by the "nearest" or most probable matches for your artist of interest (algorithm described here).

music meets möbius

Making Music with a Möbius Strip : "It turns out that musical chords naturally inhabit various topological spaces, which show all the possible paths that a composer can use to move between chords. Surprisingly, the space of two-note chords is a Möbius strip."

There is Nothing New Under the Sun

She sat zazen, concentrating on not concentrating, until it was time to prepare for the appointment. Sitting seemed to produce the usual serenity, put everything in perspective. Her hand did not tremble as she applied her make-up; tranquil features looked back at her from the mirror. She was mildly surprised, in fact, at just how calm she was, until she got out of the hotel elevator at the garage level and the mugger made his play. She killed him instead of disabling him. Which was obviously not a measured, balanced action--the official fuss and paperwork could make her late. Annoyed at herself, she stuffed the corpse under a shiny new Westinghouse roadable whose owner she knew to be in Luna, and continued on to her own car. This would have to be squared later, and it would cost. No help for it--she fought to regain at least the semblance of tranquillity as her car emerged from the garage and turned north. Nothing must interfere with this meeting, or with her role in it. "Melancholy Elephants," an enthralling, Hugo Award-winning short story by Spider Robinson about a disciplined operative, a powerful senator, and a crucial mission to preserve humanity's most precious resource.

What is up with Noises? (SLYT)

What is up with Noises? A fascinating explanation of why we hear sounds and music the way we do. It's a long video, but it's worth it!

Transcendental Music

Happy Tau Day! τ (2 × π, that is, 6.28...) is the number of radians in a turn. Translating the digits to notes even makes beautiful music. (By comparison, what pi sounds like). Previously.

Explorations of a Recreational Mathematician

Let's say you're me and you're in math class, and you're supposed to be learning about factoring. Trouble is, your teacher is too busy trying to convince you that factoring is a useful skill for the average person to know with real-world applications ranging from passing your state exams all the way to getting a higher SAT score and unfortunately does not have the time to show you why factoring is actually interesting. It's perfectly reasonable for you to get bored in this situation. So like any reasonable person, you start doodling. [more inside]

Algorithmic Music

The principles of Harmonics were discovered by Pythagoras c.587-c.507 B.C. during travels to Egypt and throughout the ancient world. Hans Kayser made a profound philosophic study of harmonics in the 20th century. Algorithmic composition is the technique of using harmonic algorithms to create music. Drew Lesso has been creating algorithmic music since 1975. Samples like Crystal, Constellations, or Planet Earth demonstrate the math behind the music. Over the years, Lesso has collaborated with many other musicians and poets to create an airy, evolutionary legacy.

Music of golden proportions

Zelda and the Golden Ratio. A fascinating examination of the music from Nintendo's Zelda games, and the recurring appearances of 0.618, the bisection point on a line at which the relationship of the shorter segment to the longer one is the same as that of the longer section to the whole line.

"This ain't no disco/This ain't no foolin' around"

Mathematical proofs in sanus, with some visualization from Martin Wattenberg's The Shape of Song. "The music here...is a raw and unadorned representation of the mathematics itself, involving few human preconceptions beyond a basic mapping needed to accommodate the Western tonal scale."

What makes a hat into hate?

That's Mathematics! Warning, contains bad camera work, worse editing, a rather complicated homework problem, a few mathematical in-jokes, illegible chalkboard writing, and a 13 minute performance by Tom Lehrer.
