Piano Sonata No.5 was written in 1974. Stylistically, it moves on from works completed in the 1960s which betray a synthesis of Fišer's own musical language and the stimuli of New Music. With theexception of the final passage, the sonata exclusively applies the mode B flat-B-C-C sharp-F-F sharp-G, which was first used in a narrowed six-note form in 1965 in Fifteen Prints after Dürer's Apocalypse. Formally, the piece isarranged into short contrasting sections which are created from brief repetitive ostinato motifs. With minimal use of thematic and expressive material, the composer achieves effective dramatic abbreviation of the kindwhichculminated in works from the 1960s. This musical treatment is abandoned only in the final, lyrical part, which anticipates the future development of Fiser's musical language, leading to its simplification and overalldramatic reduction.
Piano Sonata No.5 was first published in 1996 by Bärenreiter Editio Supraphon Prague, in a re-print of a transcription provided by the Czech Music Fund in whose preparation the composerwas also involved at the time. The new edition consistently adheres to this authorised copy of the work, while confining itself to the correction of several apparent omissions and errors.
