The adufe is one of the rare square double headed frame drums. A wooden structure is covered with rawhide from a sheep or goat and some rattling objects are thrown inside. The adufe is traditionally played by women in the interior provinces of Portugal, Beira Baixa and Trás-os-montes. In some regions it is simply called pandeiro (frame drum). Its sound invites meditation or even trance. To play it the adufe is held by the two hands with one corner pointing to the skies. The hands beat one of the skins and shake and hold the instrument
