An impromptu in an instrumental composition supposedly written "in promptu" or improvised. The term "impromptu" first appeared in the work of Jan Vaclac (Hugo) Vôrisek (1791-1825, the Impromptus Opus 7 were published in 1822). Schubert takes up this title and uses it for his very structured lyric Pieces: D 935 / 1 Movement in a loose sonata form - D 933/2 Rather slow minuet broken up by an agitated trio - D 935/3 Variations on the theme for the 4th acts interval in Rosamunde (music for the theatre) - D 935/4 A frantic dance of Central European inspiration. About Schubert, Schumann once wrote: "He got sounds for the most delicate impressions, for the thoughts, even for the different situations of our life. However numerous the man's thoughts and efforts, the music of Schubert responds to all of these diversities" Schubert, musician of the soul, of love, of illuminating shadows. Using the autograph manuscripts and original editions available today, we have produced an edition which corresponds faithfully to the intentions of the composer. Schubert often did not complete phrasing marks: we have restored his omissions, here included in parentheses. The same was done for some accentuations (dotted notes, legatos, accents, etc.). At the bottom of the page, some interpretations of ornaments (grupettos, appoggiaturas, etc.) are recommended.
