Definition & Meaning of "intonation"

What is "intonation"?

Intonation refers to the variation in pitch while speaking, which helps convey meaning, emotion, and attitude. It involves the rise and fall of voice pitch over phrases and sentences, indicating whether a statement is a question, a command, or an expression of surprise, among other things. For example, in English, a rising intonation at the end of a sentence often suggests a question, while a falling intonation may indicate a statement or command. Intonation is important for effective communication, as it can change the intended meaning and help listeners interpret the speaker's emotions and intent.
