The arrival of valved brass instruments in Paris in the mid-1820s is attributed to Gaspare Spontini who had lived and worked in Paris before but who had taken a position in Berlin that had exposed him to this technology. Its use by German players inspired him to send some samples to influential teachers he knew at the Conservatoire and Garde nationale. These instruments were examined by Louis-François Dauprat, the Conservatoire horn teacher, and his student, Joseph-Émile Meifred, a specialist in low horn playing. The result was two methods, some articles in Revue Musicale, a premiere performance at the Société des concerts in March of 1828, and then two additional works at the time that used valved horns.
