 The ordering of the pieces in the albums does not reflect the sequence or the dates of their composition, which range from 1857 to shortly before Rossini's death in 1868.The title "Péchés de vieillesse" was given by Rossini only to volumes V to IX, but has since been extended to the complete set.He also referred to his "Petite messe solennelle" as "the last of my "péchés de vieillesse"", but it is not formally part of this set of works.
