During the last decade of his life Rossini wrote numerous vocal and instrumental pieces which, with his usual irony, he entitled Pèchés de vieillesse. He then organized them in various albums that reflect neither the date of composition (very often not indicated) nor the performing medium. Two of these collections are published in the present volume: Album français and Morceaux réservés. For the most part they consist of pieces intended for performance in the composer's drawing room by one or more solo voices with piano accompaniment, but there are also choral movements. Some items have never heretofore unknown versions which are issued here for the first time.
