Scandalli is an Italian accordion manufacturer based in Castelfidardo, in the Marche region long considered the heart of accordion making. The company traces its origins to 1900, when Silvio Scandalli began building accordions with his family in Camerano, growing the workshop into a major industrial operation by the 1940s. In 1946, F.lli Scandalli merged with Settimio Soprani to form Farfisa, the conglomerate that later became famous for its electronic organs. After Farfisa wound down its multi-product operations in the 1980s, the Scandalli name was revived as a dedicated, hand-built accordion brand under the direction of Mirco Patarini and the Menghini family.

The range covers piano and chromatic button accordions across several lines, including Linea Tradizione for classical voicing, Linea Intense for high-performance concert work, Linea Groove for versatile multi-style playing, Linea Tierra aimed at Latin styles, the lightweight Linea Air, and Linea Conservatorio for students. Vintage models like the Super VI remain sought after on the used market. The brand is associated with handmade reedwork and is one of a handful of Castelfidardo makers entered in Italy's Register of Historic Brands of National Interest.
