after Franz Schubert
after J. S. Bach
after Joseph Haydn and Hanns Eisler
for string quartet
The second movement from Joseph Haydn's "emperor's quartet" is
re-composed in such way, that not "Gott erhalte Franz den Kaiser" is
varied, but "Auferstanden aus Ruinen" by Hanns Eisler, that means not
the present national anthem of the Federal Republic of Germany, but the
one of the former German Democratic Republic.
