Born in Naples in 2000, Galietto began learning the guitar with her father, Alberto. She won the EuroStrings Guitar Competition in Petrer, Spain, in 2021 and has performed extensively across Europe and the United States. Her studies have taken her to the University of Music and Performing Arts Graz, where she has worked with Paolo Pegoraro and Łukasz Kuropaczewski.
While the audience awaited the results, the stage welcomed back Ausias Parejo, winner of the 2025 edition. His performance brought the international tour awarded by the competition to a close, revealing a thoughtful and refined musician. His return offered a fitting connection between successive generations of Pittaluga laureates.
