Mathemusician Vi Hart Explains Space-Time with a Music Box and a Möbius Strip
by Maria Popova
“The fabric of the universe via backwards Bach.
If mathemusician Vi Hart — who for the past three years has been bringing whimsy to math with her mind-bending, playful, and illuminating stop-motion musical doodles — isn’t already your hero, she should be, and likely will be. (Cue in the GRAMMYs newly announced search for great music teachers.) In her latest gem, Hart uses music notation, a Möbius strip, and backwards Bach to explain space-time:
Music has two recognizable dimensions — one is time, and the other is pitch-space. … There [are] a few things to notice about written music: Firstly, that it is not music — you can’t listen to this. … It’s not music — it’s music notation, and you can only interpret it into the beautiful music it represents.
Also see Hart on the science of sound, frequency and pitch, and her blend of Victorian literature and higher mathematics to explain multiple dimensions.
For a decidedly less whimsical but enormously illuminating deeper dive, see these 7 essential books on time and watch Michio Kaku’s BBC documentary on the subject, then learn how to listen to music.”

AN : Just as the author , Maria Popova , writes of mathemusician Vi Hart : “If mathemusician Vi Hart — ….- isn’t already your hero, she should be, and likely will . “….so you would be enamoured with the effervesent writings and curations of Maria through her site “BrainPickings.com ” . Absolutely a gem of ideas, innovation and thought leadership !
“It sometimes seems as though the world of classical music doesn’t change. Most of the music is from a canon that may be hundreds of years old; most of the time the musicians are still formally clad, the men in the evening dress of a century ago.
In one important area, however, new ways of doing things are starting to appear. Technology is changing the ways in which musicians rehearse and perform.
Pianist Kirill Gerstein sparked intermission discussions late last year when he performed Thomas Adès concerto “Seven Days” with the St. Louis Symphony Orchestra using an iPad with a wireless foot pedal in lieu of a conventional score.
In an interview, Gerstein said he’s been using his iPad for 2½ years, the first, he thinks, among classical pianists. He uses it with contemporary music, where memorization is not expected, and in chamber music.
The tablet has practical advantages: It is lit, making reading it easier and eliminating concerns about lighting. It also eliminates the need for page turners. “They may turn the page too soon or too late, or make noise,” Gerstein said. “In cases like this, it is helpful to play with the iPad. I know exactly when I want to turn, and I turn it for myself.” His system has never crashed.
To do the turning, Gerstein uses a Bluetooth-enabled foot pedal called an AirTurn. He gets new scores from their publishers, or makes PDFs of older music by scanning scores from his own library.
In the case of out-of-copyright works, he recommends IMSLP.org. The International Music Score Library Project is community-sourced, like Wikipedia, and Gerstein calls it “an amazing resource.”
The site is copyright compliant, so there’s nothing from after 1923, and it’s free. “There are the most imaginable and unimaginable things,” Gerstein said. “Maybe you won’t find the edition of the Franck sonata from 1980, but you will find the original (edition) and four others. Things that used to be difficult to find are up there.”
Otherwise, Gerstein works from paper versions. “I do think it’s very important to keep buying paper versions of sheet music. We do want publishers of accurate versions around.”
With the iPad, he can tweak his scores by combining the piano part and a full orchestra score to give himself important cues. Sometimes he plays from the full score. By eliminating the white space of the margins, the notes become almost as large as in the printed score.
“Then, of course, there is the fact that I can carry a music library,” added Gerstein. “I can look at (scores) while traveling. It’s not possible with paper, just from the luggage side. Today, I decided to read the Franck sonata; it took a minute to download the score, and then I was happily playing it.”
St. Louis Symphony Orchestra section cello Bjorn Ranheim admires Gerstein’s score-on-tablet setup and wishes the SLSO could have the same.

AN : classical music meets new classic technology…and is all the better for it. Nice examples of how that works in the lives of several musicians and groups.
…”As social animals, we want to discover and share music, and external forces are working in concert to unbundle all types of media. These forces helped produce services like Grooveshark and Rdio, new incarnations of the Rhapsody subscription model, where users pay monthly fees to access catalogs and additional fees to carry that music with them. In parallel, services like Shazam and SoundHound help us identify music we hear, and Instant.fm, Last.fm, and 8tracks help us create new playlists and keep track of what we listen to over time.
In 2011, these primal urges have roared to life, producing a flurry of services aimed at helping us discover, share, and network around music experiences. A few have built on the “following/follower” model, such as SoundCloud, which allows users to capture and share a variety of sounds (not limited to music), and SoundTracking, which allows users to broadcast the songs they’re currently listening to. A new service, Rexly, adds a recommendation layer on top of iTunes accounts, built on the intuition that we don’t discover music we like via the wisdom of the crowd, but rather through a small group of influential friends we admire. All of these companies are interesting in the sense that they create a dedicated channel for us to discover, share, and build relationships around music online.
Then there’s the 800-pound gorilla in the room: Facebook. The current rumor is that the largest social network will shortly launch a new offering integrated with Spotify that gives users access to a massive song catalog, with the added sweetener that Facebook already has captured information around what musicians we “like,” giving it an opportunity to provide targeted add-on services alongside our favorite tracks. With Sean Parker advising Spotify, it seems as if his presence alone will make this happen on a massive scale.”
