Morsima-Amorsima ST/4-1, 030762 瑟納基斯 鋼琴四重奏 博浩版

標題解釋"Moros" = 命運，死亡。Morsima"="命運"。"Amorsima"（"a "是否定語氣詞）= 不是來自命運的東西。該作品採用了與 ST/10 相同的程式，但使用了不同的樂器組合。這部作品是由巴黎的 7090 IDM 電子腦按照謝納基斯設計的特殊隨機（概率論）"程式 "計算出來的。該 "程式 "源於《Achorripsis》中提出的 "作曲最低規則 "理論，但直到四年後才在法國 IBM 公司實現了 "機械化"。這個 "程式 "是作曲家多年來在音樂創作中引入的隨機法則的綜合體。他命令電子腦逐一確定先前計算出的序列中的所有聲音。首先是出現的時間，其次是音色的種類（琶音、撥弦、滑音等）、樂器、音高、出現滑音時的漸變、聲音發射的持續時間和動態"

原文簡介:
Explanation of the title: “Moros“ = Fate, death. “Morsima” = that which comes from Fate. “Amorsima” (“a” being the negative particle) = that which does not come from Fate. The work is the result of the same programme as for ST/10 but for a different combination of instruments. The work was calculated by the electronic brain 7090 IDM in Paris in obedience to a special stochastic (probabilist) “programme” devised by Xenakis. This “programme” was derived from the thesis of “Minimum rules of Composition”, which had already been formulated in “Achorripsis”, but it was not until four years later that it became possible to have it “mechanised” at IBM-France. The “programme” is a complex of stochastic laws which the composer had been introducing into musical composition for a number of years. He orders the electronic brain to define all the sounds of a sequence, previously calculated, one after the other. First, the time of its occurrence, next its kind of timbre (arco, pizzicato, glissando, etc.), its instrument, its pitch, the gradient of its glissando where that occurs, the duration and dynamic of the emission of sound.
