Sommario/riassunto |
|
Der rezeptionsgeschichtliche ›Urknall‹ von Richard Wagners Werk fand bezeichnenderweise an einem Ort statt, der sich in einem Spannungsfeld zwischen Provinz und Residenz, Tradition und Fortschritt, Idee und Verwirklichung befand: im Großherzogtum Sachsen-Weimar-Eisenach. Hier verbanden sich Franz Liszts auf die Zukunft ausgerichtetes Wirken und das Erbe der Weimarer Klassik unter der Regentschaft eines ambitionierten Weimarer Hofes zu einer nicht unproblematischen Synthese, von deren Folgen auch Wagner nicht unberührt blieb. Die Beiträge des Bandes untersuchen diese Wechselwirkungen zwischen Kultur und Politik. |
»Ein kenntnisreicher, gut recherchierter Überblick zu Wagners und Liszts Wirken in Weimar und Eisenach. Durch die Betonung der vielseitigen Verflechtungen des kompositorischen Schaffens und der musikästhetischen Programme mit materiellen, sozialpolitischen und geographisch-lokalen Bedingungen ergänzt der Band die bereits erschienene umfangreiche Literatur zu Wagners Biografie und Wirkung.« |

»Ein relativ schmaler, doch ergiebiger [...] multiperspektivistischer Blick auf Wagner in seinen Beziehungen zu Weimar und Eisenach.« |
