It's a piece of music, using harpsichord MIDI sounds from a music editor software.
As for the music itself, it's a mix between some quite heavy avant-garde style and more pop one, so i think some peoples will call it neoclassical or post modern, i don't know.
You have a first part using a certain amount of motives, then just after a simili glissando, every motives is repeated in the same order but with some huge transformations.
Dramatically, it's more in three parts, one until the so called glissando, the second let the energy slide down, and then the third goes toward the ends with more and more energy until the last very pop theme is back again, repeting mrecylessly !
