At his death in 1791, Mozart left over 100 incomplete instrumental pieces from the last decade of his life

As a body of materials they can tell us much about his development as a composer over that period, his working methods and musical styles.

Many of them were not abandoned because of creative issues but fell victim to circumstances or were ‘works in progress’ when Mozart died.

The aims of this research project were to:

  • Undertake detailed stylistic analyses of the fragments
  • Comment on them critically through completions that explore their musical potential
  • Make them available in performing editions.

The methods used included:

  • Drawing on the latest bibliographical work on the sources and adding to it
  • Analysing each fragment in the light of Mozart’s changing compositional preoccupations in other works he completed at the same time
  • Undertaking multiple completions of each fragment in order to acknowledge their intrinsic openness and explore alternative hypotheses about them
  • Testing new concepts about Mozart’s working methods and style in the composition of the completions.
