Argument: In a council of the Gods, Minerva calls their attention to Ulysses, still a wanderer.
In medias res is the technique of starting a work in the middle. For example, The Odyssey begins when Ulysses is still wandering the earth after the Trojan War, skipping how he became a wanderer and jumping right into things.
In music, you might hear an in medias res beginning in multiple ways:
1) A loud, fast opening (you are right in the middle of the action!)
2) Conversely, a soft opening which increases in volume (the music slips into being, like a continuation of something that came before; it is hard to tell where the beginning actually is)
3) Jumping right into a musical idea (without any softer, slower or other introductory sounds, so the music immediately presents you with a crucial scene or idea)
Have you heard any pieces like this? Or do you know any pop music that works in this way?
