Variations Sur Un Thème De Mozart is a piece composed by Reynaldo Hahn and dedicated to Philippe Gaubert. Composed after a tune by Mozart and scored for the Flute, this piece features a main theme and a total of seven variations which follow one another.

The Flute score features many trills, especially in the Variation 2, some fast rhythms and up to 6 flats on the key for the Variation 4. It would require a good mastery of techniques for these challenging parts.
