African drum language

The traditional drumming found in Africa is actually of three different types. Firstly, a rhythm can represent an idea (or signal). Secondly it can repeat the profile of a spoken utterance or thirdly it can simply be subject to musical laws.

Drum communication methods are not languages in their own right; they are based on actual natural languages. The sounds produced are conventionalized or idiomatic signals based on speech patterns. The messages are normally very stereotyped and context-dependent. They lack the ability to form new combinations and expressions.

In central and east Africa, drum patterns represent the stress
Stress (linguistics)
In linguistics, stress is the relative emphasis that may be given to certain syllables in a word, or to certain words in a phrase or sentence. The term is also used for similar patterns of phonetic prominence inside syllables. The word accent is sometimes also used with this sense.The stress placed...

Prosody (linguistics)
In linguistics, prosody is the rhythm, stress, and intonation of speech. Prosody may reflect various features of the speaker or the utterance: the emotional state of the speaker; the form of the utterance ; the presence of irony or sarcasm; emphasis, contrast, and focus; or other elements of...

s alone.

In certain languages, the pitch of each syllable is uniquely determined in relation to each adjacent syllable. In these cases, messages can be transmitted as rapid beats at the same speed as speech as the rhythm

 both match the equivalent spoken utterance.

Misinterpretations can occur due to the highly ambiguous nature of the communication. This is reduced by context effects and the use of stock phrases. For example, in Jabo, most stems are monosyllabic. By using a proverb or honorary title to create expanded versions of an animal, person's name or object, the corresponding single beat can be replaced with a rhythmic and melodic motif

 representing the subject. In practice not all listeners understand all of the stock phrases; the drum language is understood only to the level of their immediate concern.

Some people such as the Melanesians extend this idea further by freely inventing signs to make up their drum signals. This is in sharp contrast to the Efik tribe of Nigeria

s of which are parts of song melodies, quasi-poetic rhythms or purely personal rhythms.

When a drum is used in speech mode, it is culturally defined and depends on the linguistic/cultural boundaries. Therefore, communication suffers from translation problems as in vocal communication. There is no international drum language.
