Within this same decade, Webern also published his Op. 1, the Passacaglia for Orchestra. Just as Berg did, Webern showed an originality coupled with glimpses of his teacher (in addition to the late Romantics such as Wagner and Mahler).
While the differences between the two pieces are clear -- mainly the difference in genre, instrumentation, and tonal language -- their similarities are surprising. By showing the backgrounds of Berg and Webern's musical training and closely examining each piece's compositional elements, a valid comparison can arise.
This is the research topic I'm currently investigating.
