The genesis and genius of Bartok's Concerto was mingled with his love for Stefi Geyer. As Hungarian Tristan pursuing his Isolde, he sounds allusions to Wagner's paean of unfulfilled love. In transposing the ideal into the real, Bartok enlists folk sources voicing pristine truths of peasants. While biography and Tristan allusions supply the keys to Stefi's Concerto, the Tristan grief motif serves as bridge from idealized romance to the pentatonic simplicity of peasant realism. In these tensions private love and public life, and esoteric romance and raw worldliness are provoked and reconciled. The rise and fall of living romance and its musical mirroring against peasant scales and rhythms is background to "Tristan" ruling a score that incites and resolves the clash of two conflicting worlds
