ENTROPY CHANT is the piece of sounding silence. This work investigates into narrative property of the silence and visual gestures of 'the performer on stage' within the context of the musical piece - the 'silence within the sound' and 'sound within the silence'. Which begins and results by the energy of the internal mechanism of 'the intention' and the sound production over time – gradually shaping the liquid self-changing form of a non static sonic sculpture of the piece.
The breathing dynamic gestures, transforming melodic motives and textures, the echoing ghost-sounds of appearing and disappearing shadow overtones, a continuously created new points of departure, shifted gravity centers, melted perception of time – all invite the listener into its weary, androgynously fragile, frozen sound scape of the moving towards or forward in time, yet never reaching.

The term 'entropy' (from Greek: εντροπία [entropía] - a turning toward; εν [en-] -in; τροπή [tropē] - turn, conversion) is used indirectly, focused around the inertia and the level of momentarily available working of energies in the musical context.
In information theory: /    In simple terms, entropy in information theory is as a measure of unpredictability, a measure of uncertainty in the expected value of the information contained in a message. Meyer (1956) postulated that meaning in music is directly related to entropy – that high entropy (uncertainty) engenders greater subjective tension, which is correlated with more meaningful musical events.

In physics:/    Entropy is not a qualitative thing, but quantitative. When physicists talk about entropy, they talk about change in entropy and not about something absolute. It's a macro measure that describes a macroscopic system consisting of different small (microscopic) elements. Entropy is the only quantity in the physical sciences that "picks" a particular direction for time, sometimes called an 'arrow of time'. As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system will increase.

In a closed system, these small elements are initially all in different states and interact with each other, producing useful work. Entropy describes a potential of such a system to produce 'useful work'. By producing useful work, system will be changing it's internal state so that differences in it's internal organization will be leveled. In the end, you will have a settled system where there is no difference in internal states of it's individual elements, so they can't produce any useful work by interacting with each other. This state is called equilibrium and in these state the system reaches it's maximum entropy.
