Albanian iso-polyphony is characterised by songs consisting of three parts: two
solo parts, a melody and a countermelody with a choral drone. Four-part singing
is found less often and only among the Labs. This form consists also of two solo
parts, but is accompanied by a double drone, one choral and one solo. The
structure of the solo parts differs according to the different ways of
performing the drone, but there is also a great variety of structures within the
two drone types, especially in the pedal style that is popular with all groups
performing this music.
Over the last decades, the modest rise of cultural tourism, along with the
growing interest of the research community in this unique folk tradition, has
contributed to the revival of Albanian iso-polyphony.
