About this piece

Sigismund Neukomm, Joseph Haydn's favourite pupil, lived in Rio de Janeiro from 1816 to 1821 and wrote about 70 works there. He dated these six variations on a theme by Kozeluch 23 November 1817 and dedicated them to Princess Carolina-Leopoldina, the Austrian archduchess who had arrived in Rio that month to marry Prince Pedro. The piano leads most of the set, but the cello shares the D minor theme, takes the melody alone in the second variation with dotted figures and a trill, plucks the fourth, and ends the work with rocking sixteenth-note string crossings and a long low D. Musica Brasilis edited the score from the manuscript in the Bibliothèque nationale de France.

Technical overview

Andante in D minor and 2/4, with every variation in two repeated halves. The cello part stays in bass clef and first position, from the open C string up to the C above the staff, with an extension for the C-sharps. It mixes quarter and eighth notes with dotted rhythms and sixteenth-note runs, grace notes, trills, staccato notes, sf accents, a pizzicato variation, a three-note chord on A and a closing D-A double stop.

Level rubric

Early Intermediate

Left Hand

  • Regular shifting among 1st–4th positions.
  • Frequent shifts with target notes & prepared approaches.
  • Introduce ornamentation (grace notes, slow trills, turns).
  • Begin basic double stops (often with one open note).
  • Combine extensions with shifting.
  • Consistent vibrato on sustained notes with speed variations.

Right Hand

  • Bow arm gains finesse and speed.
  • Introduce controlled spiccato.
  • Sautillé appears in rapid passages.
  • Expand legato into longer, sustained lines.
  • Practice advanced articulations (martelé, refined string crossings).
  • Add complex strokes for double stops/chords.

Bow Strokes

  • Use context‑appropriate strokes: legato, spiccato, martelé.
  • Subtle bow changes during string crossings.

Rhythm & Musicality

  • Increased challenges: sixteenths, dotted rhythms, syncopation, contrasting subdivisions.
  • Emphasize expression with crescendos/decrescendos & vibrato.
  • Balance technical precision with emotional delivery.
