Sanaa has a rich musical tradition and is particularly renowned for the musical style called ''al-Ghina al-San’ani'' ( ), or "the song of Sanaa", which dates back to the 14th century and was designated as a UNESCO Intangible Cultural Heritage in 2003. This style of music is not exclusive to Sanaa, and is found in other areas of Yemen as well, but it is most closely associated with the city. It is often part of social events, including the samra, or evening wedding party, and the magyal, or daily afternoon gathering of friends. The basic format consists of a singer accompanied by two instrumentalists, one playing the qanbus (Yemeni lute) and the other playing the sahn nuhasi, which is a copper tray balanced on the musician's thumbs and played by being lightly struck by the other eight fingers. Lyrics are in both classical Arabic and Yemeni Arabic and are known for their wordplay and emotional content. Skilled performers often "embellish" a song's melody in order to highlight its emotional tone.
