此曲旨在呈現，藝術是現實中隨機過程的節錄和再現。世界是由成千上萬的隨機過程交織而成，而音樂和隨機過程亦驚人地相似。音樂與股票價格或經濟指標一樣，可以被分析為時間序列或縱橫資料。它們會隨著時間推移而演變，在宏觀層面上展現出隨機行為，同時亦受最近的表現影響。

藝術和音樂不是隨機過程，而是我們在隨機過程中捕捉、節錄並再現的部分。相比起建造，藝術創作可能更接近是個減除的過程，在大千世界中挑選有趣的時刻，並加以雕琢和演繹。

Heteroskedasticity II is a musical embodiment of the concept that art is a reinterpretation of real-world stochastic processes.

Our world is a complex tapestry of stochastic processes, evident in our societies and individual lives. The unpredictability of daily life manifest as randomness; events often unfold by chance and without a predictable pattern. Every aspect of life, from the trajectory of our careers to our marital plans, is essentially a stochastic process. While we can observe and estimate broad trends and macro patterns, precise predictions elude us due to this inherent randomness.

Music exhibits striking similarities to stochastic processes. A musical composition, akin to fluctuations in stock prices or changes in macroeconomic indicators, can be analyzed as a time series or panel data. These phenomena evolve over time, displaying stochastic behaviors at a macro level while maintaining a dependency on their recent past. Their visual representations also bear resemblances.

Art, including music, can be viewed as our attempt to capture and reproduce parts of these stochastic processes that resonate with us. The genesis of art might better be understood as a process of subtraction, of selecting and reproducing moments of interest from the vast stochastic process of the existing world, rather than as an act of pure creation.
