Over three thousand entries, four volumes, an unmistakable binding: this is the new Global Encyclopedia of Contemporary Music, signed by Treccani and presented at the Milan Triennale. An ambitious work, unique in the Italian publishing scene, it embraces all the music of the 20th century up to the present day, from Mahler's symphonism to electronic experimentation, from the Rolling Stones to trap. Edited by Sandro Cappelletto and Ernesto Assante - a journalist and music critic who died prematurely - the encyclopedia represents a cultural turning point, giving encyclopedic dignity to all musical languages, not just academic ones. "We try to bring some order to the uninterrupted flow of music that characterizes our time," Cappelletto explained. The work is notable not only for the breadth of repertoire covered - from classical to jazz, rap to metal - but also for its courage to overcome the prejudices that often separate "high music" and "popular music". As Cappelletto notes, "Who could call “light” the music of Bob Dylan, an artist awarded the Nobel Prize for Literature"? According to Massimo Bray, Treccani Director General, the Encyclopedia is "an act of love toward music in its totality". Also making a difference are the thematic entries that cross different sound cultures: globalization and music, diaspora, politics, neuroscience, visual arts, and cinema. Treccani, in keeping with tradition, not only photographs knowledge, but consecrates it. And it does so today with music, in a work that serves as a tool for critical understanding and definitive cultural legitimation of artists, movements and languages often considered minor.
