Mahler Studies comprises ten innovative essays on topics spanning the range of Mahler research. Blaukopf's inquiry into critical influences on Mahler's student years provides background for Reilly's reassessment of sources for 'Opus 1', Das klagende Lied. McClatchie introduces Mahler's previously inaccessible correspondence with family members, while Feder presents insightful psychoanalytic perspectives on Mahler's relationships to his sister Justine and other women in his life before Alma. Mitchell and La Grange explore the complex issue of quotation and allusion in Mahler's oeuvre. The long-restricted Seventh Symphony sketchbook provides detailed glimpses of that Mahlerian 'world' emerging in its earliest stages, as documented by Hefling. Issues of tonal structure and coherence are addressed by Agawu and Williamson, while Franklin on Adorno's Mahler provides a clear explication of that author's dialectic engagement with the composer.
