Through meticulous historical research, the book traces his journey from his early musical beginnings in Catalonia to his decisive role in the history of Mexico, where he composed the music for the Mexican National Anthem.

The work offers an intimate look at his artistic and personal trajectory, marked by migration, cultural commitment, and exchanges between Europe and the Americas in the nineteenth century. Jaime Nunó is a key figure for understanding the cultural ties between Catalonia and Mexico in the nineteenth century.

More than a biography, this book is a bridge between two continents and two musical worlds, reclaiming Nunó as a symbol of Catalan talent projected to the world.

For more than a century and a half, the name of Jaime Nunó has remained tied exclusively to the Mexican National Anthem, of which he was the composer. Yet behind this emblematic piece lies a fascinating and, until now, little-studied figure: that of a Catalan musician who traveled across half the world and left a legacy of more than 600 works. This comprehensive biography rescues from oblivion Jaime Nunó Roca, born in Sant Joan de les Abadesses and an indefatigable traveler through Spain, Italy, Cuba, Mexico, and the United States. The result of more than a decade of research in archives, libraries, and family collections, this book sheds new light on the life and work of a cosmopolitan composer, unjustly relegated to a footnote in history. It is both a tribute to his memory and a decisive step toward the rediscovery of his oeuvre.
