Boris Porena (Rome, 27 September 1927 - Cantalupo in Sabina, 3 May 2022) was an Italian thinker, music composer and didactical expert. He was married to Paola Bučan, a famous Croatian cellist and teacher who, until her retirement in 2014 was a tenured professor at the Conservatorio di Musica in Perugia (Italy).

He was a disciple of Goffredo Petrassi – alongside other distinguished musicians such as Ennio Morricone, Aldo Clementi, and Sergio Cafaro. Although he was initially influenced by neoclassical poetics, he later evolved towards the use of the harmonic language of the late Renaissance period, which he has used with originality in order to build his own musical research which directly influenced his later compositional processes.

He started composing when only 12 years old. His career is effectively in two distinct and different periods – the first being up until 1967 during which time he gained a wide national and international success. From 1968, as consequence of the evolution of both his thought and his social involvement, he abstained from composing, a period which lasted for the next twenty years. During that time he devoted himself to a grassroots cultural practice and set up the Metacultural Centre, located at Cantalupo in Sabina (Rieti, Italy). In 1988 he began to compose again with renewed enthusiasm, starting on a new and different compositional phase.

As a musical critic he has written essays about his master, Goffredo Petrassi along with several other important texts about music; among them Musica/Società (Einaudi, 1975) stands out, going beyond purely musical issues and authoritatively examines and explores the fields of social and political analysis.

He has taught new didactics of composition at the Santa Cecilia Conservatory in Rome and he has been director of the Research and Experimental Centre "Musica in Sabina". Among his many disciples are Jesús Villa-Rojo, Luca Lombardi, Celestino Dionisi, Giuliano d'Angiolini, Derek Healey, James Clifford Brown, Claudio Pietro, Jorge (Manuel Rosado Marques) Peixinho, Armando Santiago, Oliver Wehlmann, Monica Conversano [composer], Massimo Fornetti, Alessandro De Rosa, Emanuele Pappalardo and many more.

His non compositional writings cover a number of other fields, especially pedagogy and grassroots didactics, but also philosophical reflections such as those expressed in "Metacultural Hypothesis: an hypothesis for survival" (1999).

He has a considerable and deep-seated interest in natural sciences which have led him to becoming something of an authority in entomology and especially in coleopterology.

He has written a rich collection of poetry, especially in German, his mother tongue.
