Paul Taffanel Et Philippe Gaubert - Méthode Complète De Flûte (2 volumes combined)

Considered as the practical guide for Flute, Complete Flute Method was co-written by Paul Taffanel (1844-1908) and Philippe Gaubert (1879-1941). Published in 1923, this method is strongly progressive: helping the beginner from the very start, it should develop and help them to master the necessary theory, technique and tone of this instrument. 

The 227 pages all contain descriptions and comments written in French, English, German and Spanish, which stand out by their precision and detail.
