Paolina Francesca Melchiori adopted the American custom of using her husband's surname. "Madame Tasca," as she was known professionally, performed at various venues throughout Southern California, including the Biltmore Hotel in Los Angeles, and the Hotel del Coronado in San Diego. She also sang at St. Peter's, the now-lost Italian church in Los Angeles.
Paolina was a mezzo-soprano. She trained with various esteemed voice teachers in Los Angeles and Santa Barbara. She loved to sing lyric opera, and was particularly fond of Puccini's "La Boheme." One of her signature arias was “Muzetta’s Waltz.”
Until shortly before her death, Paolina continued to perform at local Catholic Churches. Her solo work in these venues included Easter Masses and special events.
