Francisco Paulo Mignone was born on 3 Spetember 1897 in Sao Paulo (Brazil). His father was the flutist Alferio Mignone and so Francisco Mignone was musically educated from an early age. He gained local popularity at the age of 13 when he performed as a pianist and orchestra leader in the choro style under the pseudonym of Chico Bororo. He later studied music academically first at the Sao Paulo Conservatory, later at the Milan Conservatory in Italy.
Mignone returned to São Paulo in 1929 to teach harmony, and in 1933 became professor at the Escola Nacional de Música in Rio de Janeiro, a position he held until 1967. Beside his work as a teacher Francisco Mignone focused on composing and he became one of the most important and most significant musical figures of Brazilian classical music.
Francisco Mignone died on 19 February 1986 in Rio de Janeiro (Brazil).
Mignone was a versatile composer, dividing his output nearly evenly between solo songs, piano pieces, chamber instrumental works, orchestral works, and choral works. In addition, he wrote five operas and eight ballets.
In my possession are 4 handwritten scores of the following songs:
All these handwritten scores come from the estate of famous Polish soprano Wanda Werminska (1900-1988) and are signed by her. The manuscript of "Sei felice, mio tesor" is additionally signed by Francisco Mignone on the title page and dated "29.04.1932". Wanda Werminska was the prima donna of the Warsaw Opera House, but made several concert tours to South America over the decades. There is a documented concert in Rio Grande do Sul (Brazil) in 1934, another one at the Argentinian embassy in Rio de Janeiro in 1949.
The compositions are written on "Papel Weco" sheets, a South American brand. So it is likely that she received the handwritten scores directly from Francisco Mignone.
The song "Sei felice, mio tesor" was never published as far as I know. Therefore I would like to present it here:
