I'm Prof. Julian Sato, and we're exploring Lisbon's streets to trace how fado emerged from the narrow alleys of Alfama and became an international art form. Over the next 91 minutes, we'll visit six stops that document this transformation through instruments, recordings, and archival photographs that chronicle fado's evolution as a musical and poetic practice. You'll encounter pavement portraits and memorials to the singers and poets whose language became inseparable from this form, and you'll discover how the acoustic reality of tight quarters and stone walls shaped the very way voices learned to project. We'll explore how material circumstances, the trades, the proximity to water and labor, generated this art form that persists as a living practice night after night in the city's oldest neighborhoods. This is a moderate walk through steep, winding streets. Expect to pause frequently, listen closely, and uncover the secrets of how fado developed through the streets and through the singers who made it legendary.
