Polyphonic Singing from Sardinia

Sardinian folk music is the traditional music of Sardinia (Italy), characterized by striking vocal polyphony, ancient reed-pipe instruments, and a living dance repertory. Its best-known vocal form is cantu a tenore, a four-part, overtone-rich male polyphony featuring the parts bassu, contra, mesu 'oche, and 'oche (solo), now recognized by UNESCO as Intangible Cultural Heritage. Equally prominent are devotional and paraliturgical songs (gosos/cuncordu), improvised poetic forms (mutetu), lament songs (attitu), and the guitar-accompanied cantu a chitarra/chiterra. Instrumentally, Sardinia is famed for the launeddas, an ancient triple-pipe cane instrument played with circular breathing, as well as the organetto (diatonic accordion) that drives social dances like ballu tundu, passu torrau, and su dillu. Melodies favor modal inflections (often Dorian, Aeolian, and Mixolydian), sustained drones, and heterophonic textures, while lyrics are predominantly in Sardinian varieties (Logudorese, Campidanese), Gallurese, Algherese Catalan, and Italian.

Cantu a tenore is a four-part, male a cappella polyphony from the Barbagia region of central Sardinia (Italy). It is performed by small ensembles using distinct timbres that include an overtone-rich, guttural bass and a nasal lead voice. The four voices are typically called: oche or boghe (the solo lead that carries the text), mesu 'oche/mesa boghe (a middle part that thickens the texture), contra (a pressed, buzzing part that locks into the harmony), and bassu (a very low, growling part). Together they form hollow, open sonorities centered on perfect fourths and fifths with flexible, modal tunings. Texts often reflect pastoral life, love, dance, and community rituals, and performances occur in intimate circles at bars, festivals, and village gatherings. Recognized by UNESCO as intangible cultural heritage, cantu a tenore is both a living community practice and a striking example of Mediterranean multipart singing with unique timbral techniques.
