Published posthumously in 1855 (against his wishes) Frédéric Chopin’s Fantaisie-Impromptu has become a beloved test piece in the modern-day pianist’s repertoire and remains one of his most popular compositions today. Now, Alex Stopa brings this marimba and vibraphone duet arrangement of Chopin’s masterpiece to the world of percussion! By orchestrating the piece on two different instruments with two differing timbres (though at some points the vibraphonist shares the marimba), the various melodic and accompanimental lines are made more apparent to the listener. However, the cohesion between the two instruments is still present, due to the time-tested craftsmanship of Chopin’s compositional technique. Because of the virtuosic nature of the music, this is a perfect recital piece for upper-level collegiate percussionists or even professional performers. This piece comes as a professionally printed and bound score and includes individual parts in PDF format for printing or for tablet viewing.
