1. Texture . The voice at the beginning of Bill lizzard is rough as the thickness of his voice is quite thick and his pitch is low. Yet the textures of the different characters change throughout, for example the texture of the voice of the rabbit is quite smooth yet the pitch is quite high.

2. Formality At the beginning the speaker is very formal, his language is unchanging therefore it is in a frozen manner. Yet as the drama carries on ,the formality changes and it becomes informal when the different characters are introduced.
