Test data

The musical pieces used for evaluating piano reduction methods (you can see musical scores below).

  1. Tchaikovsky: ‘Danse des Mirlitons’ from the Nutcracker Suite (16 bars)
  2. Bach: ‘Jesu, joy of man's desiring’ from Cantata No. 147 (17 bars)
  3. Beethoven: Symphony No. 7, 1st movement (23 bars)
  4. Dvorak: Symphony No. 9, 4th movement (18 bars)
  5. Elgar: Pomp and Circumstance March No. 1 (32 bars)
  6. Mussorgsky-Ravel: ‘Bydlo’ from Pictures at an Exhibition (29 bars)
  7. Ravel: Bolero (18 bars)
  8. Mozart: Symphony No. 40, 1st movement (42 bars)
  9. Wagner: Prelude to Die Meistersinger von Nürnberg (27 bars)
  10. Brahms: Symphony No. 1, 4th movement (22 bars)

Piano reduction results

For each musical piece in the test data, we show piano reduction scores obtained by three methods (Iterated Fingering, Iterated Gaussian, and Iterated Distance) for three sets of target difficulty values (low, middle, and high difficulty). See the paper for details on the methods.
