How does a character's development contribute to an authors tone.

Tone is achieved through word choice (diction), sentence construction and word order (syntax), and by what the viewpoint character focuses on. Tone is created or altered by the way the viewpoint character/narrator treats the story problem and other characters, and btw he responds to the events surrounding him. ;)

Hope this helps! =D
