Nuits blanches, Op. 82

Eighteen lyric character pieces for piano, Op. 82 (1853). The title 'Nuits blanches' (Sleepless Nights) and the Jean Paul–derived German subtitle 'Blumen-, Frucht- und Dornenstücke' (Flower, Fruit and Thorn Pieces) signal Heller's position in the heart of the literary-musical Romanticism centred on Paris in the 1840s-1850s. He was a close friend of Berlioz and Liszt, an acquaintance of Chopin, and a regular participant in the literary salons. The 18 pieces range widely in character — from gentle and song-like to agitated and restless — and are among the most concentrated of Heller's character pieces. The set rewards complete performance as a cycle more than selective extraction of individual numbers, though individual pieces have been anthologised.

The Nuits blanches benefit from a wide tonal palette: from the softest, most interior pp to a full, ringing f in the more agitated pieces. Heller's dynamic markings are detailed and should be followed carefully. The pieces at the centre of the set — the 'nuit' pieces, dark and introspective — need a deeply singing, inward tone. The opening and closing pieces are more outward and energetic. As a cycle, think of the set as moving through the phases of a sleepless night: restlessness, memory, quiet reflection, and eventually dawn.
