Francesco D’Arcais studied musical composition under Lauro Rossi while completing his law degree at the University of Turin in 1851. During this period, Rossi served as his instructor in composition, providing the musical training that shaped D’Arcais’s early development as a composer and critic.
The relationship is further confirmed by accounts listing Francesco D’Arcais among the students of Lauro Rossi, who was an influential Italian composer and academic figure of the nineteenth century. Their teacher‑student connection thus represents a formative link in D’Arcais’s musical career.
