在爱沙尼亚东南部和俄罗斯联邦的普斯科夫区域生活着塞托族，这里古老的多声部合唱传统（leelo），是当代文化认同的基础。塞托的多声部合唱，包括传统的旋律，以及演唱者的传统服装，其表演特点是：领唱者唱出一行诗句，随后合唱加入到最后的部分，并且重复整个诗行。尽管歌词有时候是从前辈演唱者那里学来的，创作的技术仍是一名优秀的领唱者的标志。大多数合唱队完全由妇女组成，而最优秀的领唱者，作为塞托的‘歌曲之母"，将在塞托的节日里加冕。在塞托的农村地区，以前的歌唱几乎伴随所有的日常活动而存在；今天，这种传统的范围尽管日益局限于舞台演出，却依然充满生气地留存在族群活动中，是塞托文化的中心，也是充满活力的、受到高度重视的一个文化构成元素。塞托的多声部合唱深受旅游者喜爱，是塞托人的骄傲，也是他们的群体的核心和民族认同感的体现。

　The Seto Leelo ethnic group lives in the Pskov region of south-eastern Estonia and the Russian Federation, where the ancient multi-vocal chorus tradition (Leelo) is the basis of contemporary cultural identity. Seto Leelo 's multi-vocal chorus, which includes traditional melodies, as well as the singer's traditional costumes, is characterized by: the lead singer sings a line of verses, then the chorus joins the last part, and repeats the whole poem. Although the lyrics are sometimes learned from previous singers, the technique of creation is still the hallmark of a good lead singer. Most choirs are made up entirely of women, while the best lead singers, as Seto Leelo’s mother of songs ', will be crowned at the Seto Leelo Festival. In rural areas of Seto Leelo, where previous singing existed almost with all the daily activities; today, the scope of this tradition, although increasingly confined to stage performances, remains vibrant in ethnic activities, the centre of Seto Leelo Culture and a vibrant and highly valued cultural constituent element. Seto Leelo’s multi-vocal chorus is loved by tourists, is the pride of the trustees, but also the core of their group and the embodiment of national identity.
