Music is more than an aesthetic phenomenon: it is a gnosis, an authentic path of knowledge that Eugenio Trías (author of one of the most solid philosophical trajectories that our country has known) has reconstructed in a compendium of essays dedicated to distinguished composers, In a route that goes from Monteverdi to the last musical avant-gardes.

Bach's glorious mysteries, the duality of the tragic and the comic in Mozart, Haydn's great tales, Beethoven's heroic style, Wagner's concept of total play, Mahler's creative spirit, Schönberg's new musical theology, The eternal night of Béla Bartók, Stravinsky's sacrifices, sonorous pantheism in Cage or the musical architecture of Xenakis, appear in these pages to reveal their inner keys, their relations, their antagonisms and similarities, their oppositions and specificities. The result is not only an excellent collection of individual essays where we can appreciate the great composers in a different light, but also a narrative argument: an exciting story of ideas through music. Or, as the same author suggests, perhaps The Song of Sirens is the Great Story that some of the best western musicians have been writing over the last four hundred years.
