Charlemagne was one of the greatest figures of early medieval politics. His activities influenced many rulers, “our” Charles IV was not missing among them. The concert programme presents music that was composed for Charlemagne during his lifetime and music that was composed for his fame many years after his death. Singing with the accompaniment of medieval harps, we will connect the imperial Aachen of the late 8th century and imperial Prague of the second half of the 14th century.
