It’s a spherical video in a mathematically triplified space with symmetry in space-time

Vihart: Peace for Triple Piano. (YouTube 3D video, 4:15min)

This has got to be one of the most amazing things done with a 3D camera I’ve ever seen. Pro tip: Watch this in fullscreen mode on your phone so you can look around by moving the entire phone, and use headphones to get the full 3D sound effect as well.

Make sure to also watch

Henry Segerman: The Making of “Peace for Triple Piano”. (YouTube video, 13:52min including a “flat” version of the above 3D video).

In this video Vi Hart and Henry Sergerman explain how the video works: how they made one grand piano and one Vi look like three, but one Henry look like only two at the same time.

Vi writes a little more about this project on her weblog: Vihart.com: Peace for Triple Piano.

(This was published back in February, but I only now realized that the RSS feed of this YouTube channel stopped working.)

Friday Fun

OK Go: The One Moment – Official Video. (YouTube, 4:12min)

A music video that was shot in just four seconds and then slowed down to fit over four minutes of music. Here’s how they did it:

OK Go Sandbox: OK Go Sandbox – One Moment of Math. (YouTube, 4:33min) “Damian Kulash, lead singer of OK Go, discusses the immense amount of math behind their video,”The One Moment”.”

The rest of the OK Go Sandbox is worth checking out as well.

Perfect pitch

Last night, this MetaFilter posting sent me down a rabbit hole: What makes this song great? with links to videos by Rick Beato. I listened to 2. The Police – Every Little Thing She Does is Magic and then found my way over to videos about perfect pitch:

Perfect Pitch: How Theory and Ear Training Work Together, in which Rick Beato explained how the taught his eight-year-old son Dylan, who has perfect pitch, music theory. Dylan has perfect pitch and can sing pitch perfect as well. (I won’t even mention his skills on the piano, which you can see in other videos.)

Rick Beato also has videos on what perfect pitch is and why you cannot develop it as an adult: Why Adults Can’t Develop Perfect Pitch and Perfect Pitch vs Relative Pitch: Which Is More Important?

It turns out you can lose your perfect pitch, though, as happened to vibraphonist Gary Burton after being “without a heartbeat for half an hour” and having been reanimated: Retiring The Mallets (NPR).

For good measure, here’s another little kid with perfect pitch, who probably doesn’t know the names of the notes yet, but can tell if someone is singing a song too high or too low: Claire and the Crosbys: Perfect Pitch Test! (5-year-old Claire vs Dad). Of course, you probably all know her from singing You’ve got a friend in me and from being on the Ellen Show multiple times.
