Music, as indeed all the arts, is a historical process. What we can listen to today acquires meaning only because of what was composed and played not only yesterday but throughout the time between the Middle Ages and yesterday. Unfortunately, for strange reasons, knowledge of so-called “cultured” music (a term I dislike) is concentrated in a period that comprehensively covers the Baroque, Classicism, and Romanticism. Already, beginning with the period from the late nineteenth and early twentieth centuries, many authors begin to thin out their treatments and leave it to the reader/listener to delve into what happened next.
