The Studies by G. Galle may be undoubtedly ranked among the most useful material intended for even mastering the skill of performers, i.e. technical strength and agility making for the distinct strokes on the instrument.
As G. Galle is known to belong to the romantic age in music, the studies seem to reveal all the best musical peculiarities of the 19th century.
However, as the trumpet's gamut is limited, the work with this material should be continued in C and in D pitches. Meanwhile, the French horn allows the studies to be performed in original, being a wonderful educational material for the students of conservatoire.
