Gabriel Pierné (1863-1937) was a French composer, conductor and organist. Despite being predominantly remembered as a conductor, his Impromptu-Caprice remains a popular performance piece in the advanced harpists' repertoire.

Pierné studied at the Paris Conservatoire before taking up the position of chief conductor for the concert series, Concerts Colonne in 1910. He remained in the post until 1933, and during this time, he notably conducted the world premiere of Igor Stravinsky's 'The Firebird'. Pierné composed for a variety of instruments, Impromptu-Caprice being one of four solo works by the composer. This Pierné piece for Harp contains many characteristics typical of the French style, such as significant tempo changes, flourishes of semiquavers and many alterations in dynamics. Impromptu-Caprice is a varied piece essential to the repertoire of aspiring harpists.
