Product details
Entropy is a work for solo piano based on the physical process of the diffusion of energy. I was inspired by this concept and began working on a technically demanding and aurally challenging piece. I wanted to create a fast, energy-filled, explosive piano work that deeply engages the performer on a physical level.
Entropy is the measure of unavailable energy within a system or
entity. For example, unburnt petrol has low Entropy, but a high
potential energy. When the petrol burns, the amount of
unavailable energy (the Entropy) increases. This piece is based
on the scientific principal that as energy diffuses (decreases),
Entropy (measure of unavailable energy) increases. Entropy can de
described as a concentrated energy being diffused or spread out,
or the deterioration of an energetic state.
The direction of energy flow always occurs from a concentrated to
a diffused state. This is why we know that reversed footage of a
diver springing back up to a diving board from the water is never
possible, because the flow of energy is moving backwards and
defies the laws of Entropy. In some respects, this work mirrors
the energy flow of everyday life and the massive amounts of drive
found in rapidity, repetition and extraordinary human movement,
such as that of piano playing.
The aim of the piece is to illustrate musically the process of
the breakdown of energy and the build-up and takeover of the
non-physical process of Entropy. I wanted to portray not only the
flow of energy from a concentrated to a diffused state, but focus
on the build up of a sub-state - one form overtaking another as
part of a narrative process. In this respect the piece consists
of two themes, playing against each other and intertwining as the
music reaches its climax. Using simple quartal and quintal
harmonies, swift textures and rapid figurations, I have worked
from a thematic centre and spread my musical material gradually
outwards, aiming to represent the Entropic effect in music.
