Thanks to people as Art Tatum, ordinary pieces of pop music can be turned into jazz. Now Tatum did it differently—he wasn’t a swing artist—but he showed the swing artists what was possible with jazz. Again, I offer a Swing Girls clip of them doing a swinging version of “Over the Rainbow” as one can hear how the original piece is “sliced” into riffs and then assembled together to form the song. It’s all in the arrangement:

In a similar vein, here is another Japanese group of swing kids—Little Cherries—again, mostly girls. The opening song is a swinging version of Glenn Miller’s “Little Brown Jug.” Notice how the basic riff doubles back on itself so that it can then be repeated with a fluid continuity. That’s an essential feature of swing structure. It uses that loop to propel itself forward the same way a satellite uses a planet’s gravity as a slingshot to propel itself further and further out into space. It’s a complex concept but the execution is literally child’s play if the band is trained right and understands the concept—in this case building a composition out of repeatable riffs. With the right training, kids can do it.
