What are tonal lanuages and what are they?

Tonal languages are languages in which the pitch or tone used when pronouncing a Word can change its meaning. In these languages, different tones can differentiate Words that otherwise have the same phonetic structure. For example, Mandarin Chinese is a well-known tonal language with four distinct tones, where the syllable "ma" can mean "mother," "hemp," "horse," or "to scold" depending on the tone used. Other examples of tonal languages include Vietnamese and Thai.
