John Rothgeb’s analysis of the “Tristan chord” engages a large intertextual network, stretching back to the Baroque and centering on recitative. Examples of a specific figure of recitative, usually associated with the asking of a question, are presented and analyzed. Examples include passages in Wagner's operas before Tristan.
