This piece was created in Athens in 1962, directed by Lukas Foss, and won first prize in the Manos Hadjidakis Competition.
Meaning of the title: 'Moros' - destiny, death; 'Morsima' – what comes from destiny; 'Amorsima' (the 'a' being privative) – what does not come from destiny.
It is the result of the promotion of the same ST/10 programme but for a different variety of instruments. The work was calculated by the electronic brain 7090 IBM in Paris using a special stochastic (probabilistic) programme invented by the composer. This programme is a derivative of the thesis Minimum of composition rules which had already been
formulated in Achorripsis for 21 instruments, but it was only four years later that its 'mechanisation' became possible at IBM in France.
The programme is a complex of stochastic laws, ie, calculation of probabilities, that the author had been using in musical composition for several years. He instructs the electronic brain to define all the sounds in a previously calculated sequence, one after the other. First comes the date of occurrence, then its tone classification (arco, pizzicato, glissando, etc.), its instrument, its pitch, the slope of the glissando if there is one, the duration and the dynamic shape of the sound emission.
