This piece uses prime pairs with a difference of 6 (p, p + 6) to express "compromise and repulsion" within "imagination and reality." Based on the first pair (5, 11), algorithmic programming based on various pairs was conducted to generate "pitch, duration, and intensity" as well as "melody, harmony, and rhythm." The form consists of five movements based on five pairs (5, 11, 17, 23, 29), and each movement is structured by combinations that repeat sections with beat points based on two pairs (5, 11) and four pairs (5, 11, 17, 23) for a prime number of times (2, 3, 5, 7). The music progresses based on an imaginary story set over six years from 2011 to 2017.
