VSL:WEB // Play a great new musical instrument, online

In Bb 2.0 collects 16 YouTube music videos and lets you play them in any order, or all at once. And because 15 of them feature music in the key of B-flat major, the sounds match up perfectly. What the site’s creator, Darren Solomon, has really invented is a new kind of instrument.

You can choose from electric guitar, bass, trumpet, glass marimba — even a spoken-word piece (called “Information”) by one Daniel Donahoo. Solomon also invites you to submit videos of your own, which he’ll post at a later date. If you take him up on the offer, keep the following in mind: Astronomers have discovered that black holes emit a single note, which just happens to be B flat. The stars, it seems, are playing our song.
