Piano Sonata No. 8 was written in 1995 as one of the last works by Lubos Fiser. The piece indicates a clear leaning towards the simplification of his musical expression. The sharp contrasts of the individual parts are noticeably diminished which, in turn, lessens the dramatic charge. The reduction in dramatic effect is also brought about by the composer's decision to spread the mode over nine notes out of the twelve, which gives him greater scope to develop the melody and, instead of short little ostinato motifs, he uses broad, sweeping lyrical melodies. The consistency of musical expression and the almost child-like simplicity of the melody in Fiser's compositions from the 1990s are reminiscent of his film music.
This edition of Piano Sonata No. 8 is based faithfully on the composer's manuscript which is kept in the Fiser estate at the National Museum - Czech Museum of Music.
