The purpose of this study was to clarify the advantages and limitations of the Altès Flute Method, volumes 1 and 2. Altès Flute Method, which has three volumes, has been widely used by flute performers for a long time in Japan. In a previous study of this flute textbook, it was confirmed that the text is heavily used by flute performers in professional orchestras for teaching and learning. In addition, it was found that the reasons performers use this resource are affected by their experiences using it while learning. Similar responses were observed when the author administered a questionnaire. Based on these findings, we assumed that flute leaders would be unable to distinguish specific advantages of using the text. The current analysis of Altès Flute Method investigates the advantages of this method.
