Tone, as you may know, is the general attitude an author takes in the construction of a story, essay, poem, etc. that can be determined by the author's choice of words. When we look at the essay, "Murmurs," by K.C.

Additionally, there are many analogies and similes the author uses in the explanation of concepts such as when the author writes "Like children going after cookies the patterns of sloshing particles left their sticky fingerprints all over the sky." As such, one way to describe the author's tone would be informal (almost playful/humorous) yet informative.
