Have you ever heard someone say  they had music “in their bones”?

00:03

Well, if you were living in  the USSR post-World War 2,

00:06

and that person was a fan of, say, jazz,

00:08

that person could have said they  had music written on their bones.

00:11

Or, at least, written onto X-rays  of a complete stranger’s bones,

00:15

cut into a disk and carved to  resemble a very floppy record.

00:18

This was bone music.

00:20

And while it might not be the next vintage  tech audiophiles are racing to listen to,

00:24

the story behind it is pretty darn cool.

00:26

[intro jingle]

00:29

Life under Joseph Stalin’s  regime wasn’t exactly chill.

00:33

Before, during, and after World  War 2, the Soviet government

00:36

leaned heavily on censorship of all sorts,

00:39

and banned ever more kinds of music.

00:52

was the aptly-named record.

00:54

Which if you think about it for a moment,

00:56

is kind of an amazing scientific achievement.

00:58

Humans have been living on Earth  for hundreds of thousands of years,

01:01

making every kind of noise from annoyed  groans to orchestral symphonies.

01:05

But unless you were born within  the past 150 years or so,

01:09

your only option to hear any  of it was to hear it live.

01:12

The first part of making a record involves  finding a way to copy down sound waves

01:15

into a physical medium.

01:17

That’s relatively straightforward,

01:18

because sound waves are physical waves

01:20

that move through the air  and interact with objects.

01:23

They are literally ripples in the air  that our brains interpret as noise.

01:27
