Exemplifying what the mad Schumann termed "heavenly length," Schubert's great G major SQ rivals Beethoven's four late quartets, and Schoenberg's First and Fourth SQs.
Within Schubert's oeuvre, the G major SQ groups with the Rosamunde SQ, Death and the Maiden SQ, and the Double 'Cello Quintet. With performance time of approx. 55mins, the mighty G major is assuredly one of the greatest SQs of all time. The sonic textures alternate between dazzingly thick and clotted chords to shimmering translucent filligree. Incredible!
