Lou Reed had Metal Machine Music. Musician and inventor Martin Molin has Marble Machine Music. Molin, who is a member of Swedish musical act Wintergatan, has designed a gigantic machine that is an enormously complex music box that circulates around 2,000 marbles through a series of chutes and directs them to fall on particular vibraphone bars, bass guitar strings and percussion pieces. If you have a hard time imagining what I’m talking about, you’ll need to check out the video below because the end product is absolutely incredible.

Once the marbles are in place, the performer then pulls a lever to start them falling onto different vibraphone bars. The order in which the marbles fall is determined by a pinned cylinder that opens up different slots that are located directly above the vibraphone bars:

As mentioned earlier, the marbles not only fall on vibraphone bars…

…but also on bass guitar strings…

The complexity of this machine is awe inspiring. It boggles my mind how much work had to have gone into it to design a cylinder with pins that are spaced at just the right distance from one another to not only create a proper melody on the vibraphone, but also the accompanying bass and percussion parts.
