In music, light and shadow can be distributed in a special way. The two outer works are characterized by brightness and luminosity, both Anton Webern's tone poem Im Sommerwind from 1904, which has outgrown the late Romantic tradition to which the later twelve-tone composer was committed at the beginning of his career, and Antonín Dvořák's 6th Symphony from 1880, which reveals Brahms as a role model, but gains its own character with its sounds borrowed from Bohemian folklore. Mozart's Piano Concerto in D minor, a work with a strikingly darker timbre, is placed in between and shows the “serious Mozart” who, for all his cosmopolitanism and joy of playing, also reveals many an abyss.
