25, by Pablo de Sarasate is a fantasy on themes from Bizet's Carmen for violin and piano or orchestra, composed in 1881.

[4] The piece contains an adaptation of the Aragonaise, Habanera, an interlude, Seguidilla, and the Gypsy Dance.

[4] The Carmen Fantasy is one of Sarasate's best-known works[1] and is often performed in violin competitions.

Because of its delicate techniques and sanguineous passion inspired by the opera, it is considered to be one of the most challenging and technically demanding pieces for the violin.

The orchestral version is scored for piccolo and 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 4 horns, 2 trumpets, 3 trombones, timpani, tambourine, harp and strings.
