This music draws inspiration from Leonard Bernstein's book The Unanswered Question. Bernstein explores 20th-century music within the context of tonality and humanity's existence on Earth. He delves into two main subjects: Stravinsky's polyphonic approach and Schoenberg's serialism. His conclusion regarding both compositional techniques is that they ultimately retain tonal context.

In the final part of the book, Bernstein poses the question of what future music will entail. In response, I cautiously propose minimalism, freeform, and microtonality as contemporary music history following the paths of polyphony and serialism. My point is that we cannot escape the concept of tonality as inhabitants of Earth. Within this context, this piece narrates history through its three movements (1st to 3rd). The structure, musical texture, and intervals I've utilized have been influenced by observed historical developments.

Ultimately, the microtones attempted by the second violin and viola in the 3rd movement aim to present each tonic of polyphony introduced in the 1st movement and converge into the natural C note. Various aspects characterize the sounds that need to be tuned away from these microtones. Whether due to players' instincts or instruments' inherent tendencies to revert to the tuned tone, even if the second violin or viola excels at producing distinct notes, the first violin or cello might deviate from its tuning and mirror the distinct notes of the other instruments. This ultimately signifies a return to the nature of sound governed by the rules derived from natural harmonics.

Therefore, I titled the work The Music of Earth, drawing inspiration from Bernstein's reference to The Poetry of Earth by John Keats in a similar context.
