24 Melodious Etudes and Variations for Flute (Elementary) by Marcel Moyse Flute Music Score, Collection of Etudes This collection of etudes is often used for music university entrance exams and lessons. It contains 24 short etudes, used to practice making the flute sing. There were a few light markings, which have been erased with an eraser. Due to aging, there is some yellowing and staining, but it has been stored in relatively good condition. I think the contents are also in good condition.
