If you'd ask me the tones of writing then I would say it depends. Tones of writing are very different when it comes to very different stories. Stories come in various moods. Tone, in a piece of literature, decides how the readers read a literary piece, and how they should feel while they are reading it. It stimulates the readers to read a piece of literature as a serious, comical, spectacular, or distressing manner.
