String Quartet F major op. 135-Beethoven’s Op. 135 one of the last works he composed is equally famous for its compositional clarity and for the inadequacy of previous editions. The problem lies in the surviving sources forBeethoven’s autograph score contains a great many contradictions compared to his autograph set of parts. In 1827 after Beethoven’s death the German publisher of the first edition posthumously ironed out thesediscrepancies as he saw fit and later editions simply adopted his interventions. Rainer Cadenbach’s volume is the first attempt to produce an authoritative text for Op. 135. Beethoven’s contradictoryformulations are laid bare allowing musicians to make their own decisions. This ambitious new edition also finds room for ideal page turns.
