Trallalero is a highly distinctive form of polyphonic singing that originated in Genoa, Italy, known for its complex harmonies and unique use of vocal techniques. Traditionally performed by male ensembles, trallalero features a complex arrangement of different vocal parts. The name itself comes from the syllabic “tra-la-le-ro,” a playful, rhythmic filler often used in the songs.

The roots of trallalero go back to the early 19th century, though its stylistic origins are older, as it evolved from earlier rural singing traditions found in the Ligurian hinterlands, especially in the valleys of the Scrivia and Trebbia rivers. Here, peasant communities maintained strong oral traditions of group singing, often connected to agricultural festivals, religious celebrations, and local gatherings.
