He wrote poetry and philosophy books, and had a prolific career as a lyricist, composing lyrics for songs by artists such as Marina Lima (his sister), João Bosco, Waly Salomão, Orlando Morais, Ritchie, Adriana Calcanhotto, and Lulu Santos.

In 1960, Ewaldo took on an executive position at the newly created Inter-American Development Bank (IDB), and the whole family moved to Washington, D.C. where Cicero completed his secondary studies.

In 1976, Cicero went to graduate school at Georgetown University, in the United States, where he studied Greek and Latin, which allowed him to read classics such as Homer, Pindar, Horace and Ovid in the original.

Among other partnerships, those with Waly Salomão, João Bosco, Orlando Morais, Adriana Calcanhotto, Ritchie and Lulu Santos (co-author, together with Antonio Cicero and Sérgio Souza, of the 1984 hit O Último Romântico) stand out.
