In the western music tradition, sound is represented in written form through musical:

Since then, too much time has passed. I’ve taken on the role of M’s guardian of my own volition. M, the soft, haughty being, overwhelmed me with an unfathomable amount of love. I slammed the glass window shut, fearful that M would catch another cold. The old car’s interior was filled with the sharp odor of gasoline. M was allergic to a variety of medications, but she couldn’t take over-the-counter fever relievers. The voice said, “More songs.” And before the final bar finished, the voice repeated the same sounds, but with more volume. Greater music, like the dropping of the next raindrop while the lingering notes of the first still sound, falling to the ground beneath the clouds with no defined beat, greater music, the next first notes joined the spectrum in an uncalculated extempore moment until the final notes were finished, like the falling of the next raindrop while the lingering notes of the first still sound, falling to the ground beneath the clouds with no set beat, greater music, The continuous sound is referred to as music…

The origins of science can be traced back to about 3000 to 1200 BCE in Ancient Egypt and Mesopotamia.
[5][6] Their contributions to mathematics, astronomy, and medicine influenced and shaped classical Greek natural philosophy, which sought to provide systematic explanations for events in the physical world based on natural causes.

[eight] From the 10th to the 13th centuries, “natural philosophy” was resurrected by the recovery and assimilation of Greek works and Islamic inquiries into Western Europe. [9] which was later changed by the Scientific Revolution, which started in the 16th century[10] and was marked by new ideas and discoveries that contradicted previous Greek conceptions and practices. [11][12][13][14][15][16][ [13][14] The scientific method started to play a larger role in knowledge production, and many of the institutional and professional features of science did not take shape until the 19th century;[15][16][17], along with the change of “natural philosophy” to “natural science.” [nineteen]

When his wife Martha died in 1782, Thomas Jefferson wrapped a lock of her hair in a scrap of paper with an excerpt from the couple’s favorite book, Laurence Sterne’s comic masterpiece Tristram Shandy, and hid the token in his drawer.
Norman Mailer, whose 1959 novel Advertisements for Myself epitomizes writerly audacity, is a shining example.
