The treatise 'On the French Sound Aesthetics of the Traverso in the 18th Century' by Magdolna Slenker examines the sound aesthetic ideals and playing techniques of the traverso in France through historical flute schools by Jacques-Martin Hotteterre, Michel Corrette, Antoine Mahaut, Charles De Lusse, and François Devienne. The focus is on the analysis of instrument construction, body posture, embouchure, flattement (vibrato), and breathing, as well as their influence on the sound of the flute. The work also highlights the differences and similarities in the teaching philosophies of these authors and their impact on the development of traverso playing. The aim is to better understand the sound ideals of the 18th century and their influence on the traverso. This investigation contributes to grasping the significance of French flute artistry in this era and tracing its sound and technical developments.
