S‚r‚nade is an early work of Rachmaninoff, from a grouping of five short solo piano pieces titled Morceau de Fantasie written in 1892 and dedicated to his harmony teacher Anton Arensky.
Opus 3, No. 5 in B-flat minor is the final work of the set and is in a gentle waltz style, sometimes venturing into the Dorian mode. - the publisher
