Usage of background sound in The Universe in a Grain of Sand

I forgot to take picture of the scene I am describing here, but I think people who went to the screening will get which part I am describing.

While watching, I noticed that often whenever a new period of description or a demonstration of artworks start, there often accompanied a sequence of background sound. For example, the use of guitar sound when introducing electrons and how they move, and the Jazz music that played along when discussing the modern usage of electrons in precise instruments.

These sounds often brings my attention back to what the artists or researchers are discussing. Also, that sound that play alonged with interview make me less prone to loss interest when watching the relatively less interesting interview. In addition, it smooth transitions between sections that could otherwise feel discontinuous.

In week 7, we are going to discuss about sound, and I think I might expand more on the topic after studying more in depth.
