This annual competition, unique to Brussels, was created in 2021 by the Brussels International Guitar Festival.
Its purpose is to extend the classical guitar repertoire.

It pays tribute to Maestros Ilse ALFONSO (1929-2017) and Nicolas ALFONSO (1913-2001) who opened the first guitar classes in the Belgian Music Academies as well as the guitar class at the Conservatoire Royal de Bruxelles - École Supérieure des Arts in 1965.

Nicolas Alfonso was also a composer and a member of the SABAM.
Numerous works by Rodrigo, Absil, Baervoets, etc., were composed and dedicated to Ilse and Nicolas Alfonso.
