George L.Trager’s The Theory of Accentual System […] offers a rounded system for the most difficult part of phonemic analysis: the prosodemes, chiefly stress, tone, quantity.
- Harris (1942b), a pag.242

A language may have prosodemes distributed arbitrarily at various morphemes, just as phonemes are. Or it may have prosodemes limited to a predictable ordinal phoneme of each morpheme, such as having the first vowel of each morpheme long. Or it may have prosodemes which can best be described in terms of the whole length of a word, such as the alternating vowel length of Tübatulabal words, or the reduced loud stress in compounds in English, Toda, and other languages.
