Variations sérieuses, Op. 54, MWV U 156, is a composition for solo piano by Felix Mendelssohn consisting of a theme in D minor and 17 variations. It was completed on 4 June 1841. A typical performance lasts about eleven minutes.
The work was written as part of a campaign to raise funds for the erection of a large bronze statue of Ludwig van Beethoven in his home town of Bonn.[1] The publisher Pietro Mechetti asked Mendelssohn to contribute to a 'Beethoven Album', published in January 1842, which also included pieces by Liszt, Chopin, Moscheles and others, of which the proceeds would go to the Monument.[2] (Schumann's Fantasie in C was the final result of a work originally intended for the same purpose).
Mendelssohn is known to have written three sets of piano variations, but only this one was published during his lifetime.[3]
