She was the daughter of Josep Anselm Clavé, from whom she learned music.
Àurea was a composer and choral director. She wrote compositions for voice and piano, and band and choir. Her most famous composition is L’Agrahiment. She was a piano teacher at the Municipal Conservatory of Barcelona.
Àurea Clavé was also a freemason and one of the first women to join a Freemasonic society in Catalonia.
Clavé recognizes her in his testament, for which we can infer that she has been conceived outside of marriage.
