Variations on a Mozart tune, for Flute and Piano is a piece composed by Reynaldo Hahn and dedicated to Philippe Gaubert. Composed after a tune by Mozart, 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.

Reynaldo Hahn was a naturalised French composer, conductor, theatre director and singer. Best known as a composer of songs, he also wrote many pieces and melodies for different instruments.
