This document discusses tone and pitch in English. It describes common tone symbols used to denote intonation, including level, falling, and rising tones. More complex tones like fall-rise and rise-fall are also noted, though they are less common. Each speaker has their own normal pitch range, and intonation typically occurs in the lower part of this range, but with strong feelings the pitch height can increase. Different tones convey different attitudes, such as a fall for a neutral statement and rise for a question.
