## I got cosines / on a cloudy day

The goofy, lofi math music of Al G. Bra and friends: Pi Girl — Say That Funky Number, Math Guy — Mathonna's Mathematical Girl. Plus: a trailer for math thriller Live and Let Pi, featuring the title track by Paul DesCartney.

## Scale invariant art

Astroblast and Overstepping Artifacts are music videos by the project Musicians with Guns, which take the viewer through detailed tours of some beauty. Relax and enjoy.

## Beach Bells

This is a visualization of Beach Boys vocals inspired by the physics of church bells. Using a mathematical relationship between a the circumference of a circular surface and pitch, I wrote code that draws a circle for each note of the song. (Single Link Vimeo)

## Twelve Tones

*"It's just one of those days where you wake up thinking that if you jazzed up Stravinsky's Owl And The Pussycat it'd be awesome..."*[SLYT] [more inside]

## The map of music

Every Noise At Once. A map of musical genres, built by Glenn McDonald of The War Against Silence and the Echo Nest. Click on a genre name to hear a sound sample, or pop it open to see a map of bands within that genre.

## 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.

## Bach is easy. If she brings him up, you just smile and you say: “Ahh, Bach.”

## True art is irrational.

This is what pi sounds like. At least, that's one person's interpretation. There are certainly plenty of others, including touchtone pi, hammered dulcimer pi, violin pi, smooth techno pi, crazy awesome pi, vaguely unsettling pi (sounds best with headphones), and lots of piano pi. Pi has even done a duet with its buddy

(pi as music previously on metafilter)

*e*. Nothing here that tickles your fancy? Think you could do better? Why not make your own pi song? Hell, make two! If you're having trouble remembering all those pesky digits, don't worry: there's a song for that, too.(pi as music previously on metafilter)

## 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]

## The plot isn't great, but the plots are pretty good.

The OEIS Movie is simply a slideshow of one thousand plots from the Online Encyclopedia of Integer Sequences, at two plots per second with sequence-generated music. [more inside]

## Music is Math

Music is Math (lots of different variations on the page. Watch this one in full screen and with headphones.)

## Exponential, what it do?

Division: Work it out! - these girls be spittin the math.

## The Geometry of Music

The connection between mathematics and music is often touted in awed, mysterious tones, but it is grounded in hard-headed science. For example, mathematical principles underlie the organization of Western music into 12-note scales. And even a beginning piano student encounters geometry in the "circle of fifths" when learning the fundamentals of music theory. ...according to Dmitri Tymoczko, a composer and music theorist at Princeton University, these well-known connections reveal only a few threads of the hefty rope that binds music and math.The Geometry of Music

## golden ratio in the amen break

The Amen Break and the Golden Ratio by mathematics educator and author, Michael S. Schneider. Schneider, having already researched and written about the golden ratio extensively, noticed it right away when hearing the the amen break for the first time (amen break previously on the blue). While some composers have been known to intentionally incorporate fibonacci numbers and the golden ratio into their works, perhaps this is just another one of the many instances of the ratio showing up in nature.

## It's math set to music!

The Klein Four is a group of math students at the Northwestern University who delight in bringing you various lovely, well-sung A Capella songs infused with their very own and very nerdy flavour. They're not the newest of the web, having released their first CD in 2005, but witty lyrics and five-part harmonizing are definitely worth checking out. I did do a search for this and didn't find anything. Please don't kill me.

## by the numbers

Pi to 1,000 places on piano is just one of the many catchy tunes on math sonifications. And check out more interesting things on on artist Tom Dukich's site.

## Integrals!

The Integrator is Mathematica's integration capabilities, available over the web. Other online resources from Wolfram include Tones, an automatic music generator, and the venerable Mathworld, an extensive collection of math terms and theorems. (which, yes, has been mentioned previously.)

## Pianolina

The Pianolina - an addictive flash game - is something like a cross between Pong and WolframTones. Brought to you by Grotrian, piano manufacturers since 1835, the pianolina visualizes musical notes as little squares that chime when they bounce against each other or against a wall. Its sophisticated interface lets you add chords, gravity, or start with the basic notes of well known compositions like Beethoven's "Für Elise".

## Science grooves

Math And Science Song Information, Viewable Everywhere. For all those times you've needed a catchy acappella tune about doppler shifting

*[mp3]*in a hurry, there's now MASSIVE, a fully searchable collaborative database of over 1700 songs about math and science, sponsored in part by the seriously pedagogical Science Songwriters Association. Biz Markie made the cut, and so can you.*[via the always-effervescent Research Buzz]*## One two three four three four threeeeee

The Sound of Mathematics Mathematical functions whose output have been jammed into MIDI files. The results are disturbingly musical.

## The new math....RIAA style.

Not 421 CD burners

*but "the equivalent of 421 burners"*. Now, most agree the RIAA is grasping at straws trying to control something they clearly can't, but this seems to be the most amusing yet. This article offers a suggestion or two concerning the possible music industry slump.## "Self-similar syncopations: Fibonacci, L-systems, limericks and ragtime"

"Self-similar syncopations: Fibonacci, L-systems, limericks and ragtime" Along the lines of the book "Godel, Escher and Bach", an award winning essay looks at the mathmatical roots of popular music. I think I'm going to have to find a way to analyze some of my fave mp3's to see how they fall into the Fibonacci sequence...
