Tirsu

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.
