The tulum (guda (გუდა) in Laz) is a musical instrument, a form of bagpipe from Turkey. It is droneless with two parallel chanters, and is usually played by the Laz and Hamsheni peoples and by Pontic Greeks (particularly Chaldians). It is a prominent instrument in the music of Pazar, Hemşin, Çamlıhemşin, Ardeşen, Fındıklı, Arhavi, Hopa, some other districts of Artvin and in the villages of the Tatos range (the watershed between the provinces of Rize and Trabzon) of İspir. It is the characteristic instrument of the transhumant population of the north-eastern provinces of Anatolia and, like the kemençe in its area, the tulum imposes its style on all the dance and entertainment music of those for whom it is "our music".
