Marcel Moyse: 25 Melodic Studies and Variations for Flute (Intermediate) Flute Music Score, Collection of Studies These are études used to practice singing on the flute. The techniques are not that difficult, so I think these études are very helpful for both amateurs and those studying professionally. Due to aging, there are some stains, scratches, and folds. There are also some faint writing marks, but the score itself is in good condition. Please consider this a used item.
