The term “Butterfly Effect” is related to the work of Edward Lorenz and is based in the “Chaos Theory”. In brief: the phrase refers to the idea that the beat of a butterfly’s wing might create tiny atmospheric changes that may ultimately alter the course of a tornado.
The term found its way into popular culture, where it refers – inaccurately – to time travel, implying that minor changes in past events could lead to major, even catastrophic outcome.
In the above fiction it simply means that a butterfly can inspire poetry and music
