Bruna was born to the musician and politician Antonio Majocchi (1831-1907), one-time mayor of Cento, and his wife Lavinia Agnoletti (1839-1911) who was known for her rich literary, linguistic and musical skills.

Her poems Barcarola and Acque chete were published by the magazine La Riviera Ligure, and then incorporated into the anthology L'eterna chimera (Casa Editrice Fiorita, 1913, p. 38 and 40).

On 18 March 1908 her work L'intima fiamma (The intimate flame) was reviewed in the magazine La Sicilia which cited the rebellion of her verses against the distortions and cowardice of the world.

[2][3] In 1912, she won the competition of the International Women 's Association for Art with the poem Pane e Psiche (Bread and Psyche), which was considered a dramatic scene suitable to be accompanied by music.

She also wrote about childhood with an emphasis on educational and literary development, and translated into Italian such works as Polish Novels by Leon Choromanski (Sonzogno, 1920 and 1927).
