Among Beethoven's works, there are 20 pieces independently known as 'Variations.' Additionally, there are 5 pieces composed as a movement within a piano sonata, making the total number quite substantial. Their composition period spans from his youth to his late years. Regarding the 'Variations,' the majority do not have an assigned opus number. It is undeniable that Beethoven favored this musical form. However, it can also be said that a strong characteristic of this series of 'Variations' is their tendency to serve largely as studies for the improvement of his compositional technique.

These 'Nine Variations' also do not have an assigned opus number. They are variations on the aria 'Quant'è più bello l'amor contadino' from the opera 'La molinara' by the Italian composer Giovanni Paisiello.
