    Drums in communicationDeveloped and used byculturesliving inforestedareas, drums served as an early form of long distancecommunication, and were

    used duringceremonialandreligiousfunctions.

    Talking drum[edit]

    While this type of instrument can bemodulatedquite closely, its range is limited to a gathering or market-place, and it is primarily

    used in ceremonial settings. Ceremonial functions could include dance, rituals, story-telling and communication of points of order.

    Some of the groups of variations of the talking drum among West African ethnic groups:

    Tama(WolofofSenegal)

    Gan gan, Dun Dun(YorubaofNigeriaand easternBenin)

    Dondo(Akanof central Ghana andCote d'Ivoire)

    Lunna(Dagombaof northernGhana;MossiofBurkina Faso)

    Kalangu(Hausaof northernNigeria,Niger, northernGhana,BeninandCameroon)

    Doodo(SonghaiandZarmaofMali,Burkina Faso, andNiger)

    In the 20th century the talking drums have become a part of popularmusicin West Africa, especially in the music genres

    ofJj(Nigeria) andMbalax(Senegal).

    Drum languages[edit]

    InAfrica,New Guineaand the tropical America, people have used drum telegraphy to communicate with each other from far away

    for centuries. When European expeditions came into the jungles to explore the primeval forest, they were surprised to find that the

    message of their coming and their intention was carried through the woods a step in advance of their arrival. An African message

    can be transmitted at the speed of 100 miles in an hour.[2]

    Among the famous communication drums are the drums ofWest Africa(seetalking drum). From regions known today

    asNigeriaandGhanathey spread across West Africa and toAmericaand theCaribbeanduring theslave trade. There they were

    banned because they were being used by the slaves to communicate over long distances in a code unknown to their enslavers .[3]

    Talking drums were also used in East Africa and are described by Andreus Bauer in the 'Street of Caravans' while acting assecurity guard in the Wissmann Truppe for the caravan of Charles Stokes.

    Smoke signalThe smoke signal is one of the oldest forms of long-distance communication. It is a form ofvisual communicationused over long

    distance.

    History and usage[edit]

    InAncient China, soldiers stationed along theGreat Wallwould alert each other of impending enemy attack by signaling from tower

    to tower. In this way, they were able to transmit a message as far away as 750 kilometres (470 mi) in just a few hours.

    Polybius, a Greekhistorian, came up with a more complex system of alphabetical smoke signals around 150 BC. He invented a

    system of converting Greek alphabetic characters into numeric characters. It was devised to enable messages to be easily signaled

    by holding sets oftorchesin pairs. This idea, known as the "Polybius square", also lends itself tocryptographyandsteganography.

    This cryptographic concept has been used with JapaneseHiraganaand the Germans in the later years of theFirst World War.

    TheNorth American Indiansalso communicated via smoke signal. Eachtribehad its own signaling system and understanding. A

    signaler started a fire on an elevation typically using damp grass, which would cause a column of smoke to rise. The grass would

    be taken off as it dried and another bundle would be placed on the fire. Reputedly the location of the smoke along the incline

    conveyed a meaning. If it came from halfway up the hill, this would signify all was well, but from the top of the hill it would signify

    danger.[citation needed]

    Smoke signals are still in use today. In Rome, theCollege of Cardinalsuses smoke signals to indicate the selection of a newPope.Eligible cardinals conduct asecret ballotuntil someone receives a vote of two-thirds plus one. The ballots are burned after each

    vote. Black smoke indicates a failed ballot; white smoke means a new Pope has been elected.

    In general smoke signals are used to transmit news, signal danger, or gather people to a common area.

    Examples[edit]

    Native Americans[edit]

    Lewis and Clark's journals cite several occasions when they adopted the Native American method of setting the plains on fire to

    communicate the presence of their party or their desire to meet with local tribes.[1][2]

    Ymana[edit]

    Ymanasused fire to send messages by smoke signals, for instance if a whale drifted ashore.[3]

    The large amount of meat required

    notification of many people, so that it would not decay.[4]They might also have used smoke signals on other occasions, thus it is

    possible that Magellan saw such fires (which inspired him to name the landscape Tierra del Fuego) but he may have seen the

    smoke or lights of natural phenomena.[5][6]

    Noon Gun[edit]

    Noon Guntime signalling was used to setmarine chronometersinTable Bay.

    Australian Aborigines[edit]

    Australian Aborigineswould send up smoke to notify others of their presence, particularly when entering lands which were not their

    own. However, these were not complex signals; smoke simply told others where one was located.
