Additionally, individual songs, not originally intended as work songs but borrowed from other contexts, also appear to a lesser extent in Qatar's musical tradition.[8] Common themes among these songs are love and marriage. An example of one such song is Tal al-Sadoud, which is about the affection one has for their partner. Despite not originally being a work song, this song has been frequently used on pearling trips as a reminder of the sailors' loved ones at home.[9] Kuwaiti and Iraqi folk songs were often popular with Qatari sea-farers, for example, the Iraqi song Al Haliya which is sung in the wafir meter.[10] Classical Qatari melodies share many similarities with their Gulf counterparts, and most of the same instruments are used.[11]
