This string quartet is based on the last sketches Beethoven wrote shortly before his death around November 1826 for a planned string quintet in C Major. I made use of his completed wonderful introduction and the beautiful main themes of all 4 movements.
The 1st movement is written on the basis of the piano arrangement by A.Diabelli of the Andante Maestoso introduction and the Allegro main theme and another Allegro theme.
The introduction is almost completely by Beethoven. It reminds rythmtically of the wonderfull majestic and melodious introduction to Beethoven's overture op.115.
The Allegro starts with flowing eighth notes in a way similar to the quartet op.59,1 with the main theme calmly performed by the cello. In m.51 I use another wonderful and jubilent theme from Beethoven's sketches, see:
