, born 13th of March in 1779 in Paris, was pupil of the famous horn player Duvernoy. In 1799 Blangy received the first price at the Conservatoire of Paris. The time between 1810 and 1816 he was employed at the Parisian Opera. In this time he may have composed his works for the opera. In 1818 to 1820 he was Répétiteur at the Conservatoire. Beside his education in horn playing he must have received numorous lectures in composition. He was also one of the founders of the Société des Concerts du Conservatoire in 1828. There he played the second horn together with the first horn players Dauprat, Mengal and Meiferd.
It can be assumed that his change to the viola in 1831 was because of health conditions. He finished his employment on the first December in 1843 and died 10th October 1848
Airs for 2 horns in 4 suites
His four suite for two horns are collections of melodies of different composers. There are for example Mozart and Haydn and many melodies of Nicolo. This name stands for Nicolas Isouard (1775 -1818), who was a famous opera composer of that time. Suite number 1 and 2 are dedicated to Mr. Felix de Coincy and suite number 3 and 4 to son ami Dauprat. These suites are interesting also because of the different usage of tunes for the different horn parts and that both horns play the higher or lower part in the duos.
