Today, Thursday, May 26, 6-8 pm (EET+2 time zone), Christos Hatzis will give an online lecture for the 15th Festival of Audiovisual Arts at the Ionian University in Corfu, titled "Η πνευματική και φιλοσοφική μου τοποθέτηση πάνω στα θέματα μουσικής σύνθεσης και ζωής" (“My spiritual and philosophical stance on music and life”). He will be delivering the lecture mostly in Greek, but his PowerPoint presentation will be bilingual (English and Greek). Hatzis's lecture will center on what he have learned from the philosophers Pythagoras, Plato, and Plotinus, his studies on the qualitative nature of numbers, not just the quantitative, how all the above have been distilled in his concept of “Harmonia” in the late 1970’s, and how the latter has indelibly altered his view of Everything . . . “visible and invisible”.
