Henri Kling (1842-1918) spent most of his career in Geneva, where he was professor of horn and solfège at the Geneva Conservatory from 1865 until his death.
Kling’s Horn-Schule was, according to his obituary, first published in 1865. However, the work was not listed in Hofmeister’s Handbuch until the 1874-79 edition, indicating a possibly later date of original publication. In any event, the Horn-Schule is musically progressive, beginning with easy études and moving to difficult études and orchestral excerpts.
Of the materials in the method, among the more useful materials today are the duets. This set of 31 starts easy and ends with a group of attractive duets from operas of Mozart and Mehul. The first 20 are suited to the natural horn, and the remaining 11 are more suited to the valved horn. The duets may be accessed from our PDF download library or from the link directly below:
