The sounds of language can be divided into consonants, vowels, and tones--the use of pitch to convey meaning. Seventy percent of the world's languages use pitch in this way. Assuming little or no prior knowledge of the topic, this textbook provides a clearly organized introduction to tone and tonal phonology. Comprehensive in scope, it examines the main types of tonal systems found in Africa, the Americas, and Asia, using examples from the widest- possible range of tone languages.
