His remaining secular works in this late period fall into three categories: first, large scale cantatas and one oratorio "Habsburg" written on patriotic themes or in response to the international political situation, pedagogical works written to aid his students in voice, and finally simple songs, rounds or canons written for home entertainment; many with original poetry by the composer. He also composed one large scale instrumental work in 1815 intended as a study in late classical orchestration: Twenty-Six Variations for the Orchestra on a Theme called La Folia di Spagna. The theme is likely folk derived and is known as "La Folía". This simple melodic and harmonic progression had served as an inspiration for many baroque composers, and would be used by later romantic and post-romantic composers. Salieri's setting is a brooding work in the minor key, which rarely moves far from the original melodic material, its main interest lies in the deft and varied handling of orchestral colors. "La Folia" was the most monumental set of orchestral variations before Brahms' "Variations on a Theme by Haydn".
