He lived his entire life in the city of Bologna, and is best remembered today for penning the libretti for the operas La fanciulla del West (1910) by composer Giacomo Puccini, I gioielli della Madonna (1911) by composer Ermanno Wolf-Ferrari, and Conchita (1911) by Riccardo Zandonai.
His mixed heritage made him an ideal choice to serve as Giacomo Puccini's librettist for his 1910 opera La fanciulla del West; a work which he co-authored with the poet Guelfo Civinini.
[1] Set in the Western United States and adapted from David Belasco's 1905 play The Girl of the Golden West, the opera tells the story of a Californian mining camp during the 1849 Gold Rush.
[2] In addition to La fanciulla del West, Zangarini also wrote the libretti for the operas I gioielli della Madonna (1911) by composer Ermanno Wolf-Ferrari and Conchita (1911) by Riccardo Zandonai.
[1] The composer Ottorino Respighi set several of his Zangarini's poems to music, including "Scherzo", "Stornellatrice", and "Invito alla danza".
