The
talking drum is an
hourglass-shaped drum from
West Africa, whose pitch can be regulated to mimic the
tone and
prosody of human speech. It has two
drumheads connected by leather tension cords, which allow the player to modulate the pitch of the drum by squeezing the cords between his or her arm and body. A skilled player is able to play whole phrases. Similar hourglass-shaped drums are found in Asia, but they are not used to mimic speech, although the
idakka is used to mimic vocal music.
