The singer Bino Branco from the band Ferro Gaita, playing a ferrinho
The ferrinho (in Cape Verdean Creole ferrinhu [fe'?i?u]) is a musical instrument, more precisely a scraped idiophone. It is made up by a metal bar (generally of iron) that is scraped by another metal object. The player holds the bar vertically, with its lower end in the palm of one hand and the upper end leaning against the shoulder. With the other hand, the player uses a metallic object, held horizontally, to scrape the bar with up-and-down movements. A custom-made ferrinho is usually 90 centimeters long, with a straight-angle section to ease handling.
It is believed that the name "ferrinho" is an adaptation of "ferrinhos", that is the name by which the triangle is known in popular music in Portugal. In spite of the name, the ferrinho is more similar to instruments like the güiro (scraped idiophone) than the triangle (directly struck idiophone).
One of the greatest musicians who used the instrument is Codé di Dona. Other musicians with the instrument include Bino Branco from the band Ferro Gaita.
A ferrinho once used by Codé di Dona is depicted on the back of the Capeverdean $1000 escudo note issued since 2015.
