The Lokele people of the Congo use two-tone log drums to communicate phrases in their language. They can accomplish this because their language is tonal. That is, each syllable in a word has a high or low tone. The tonal patterns that result in their speech are the same tonal patterns that they drum. By communicating in this way, they create drum language in which their vocabulary is always understood in the context of phrases.
