Heinrich Domnich was the son of hornist Friedrich Domnich (1728-1790), and he went on to study and build a distinguished career in Paris [Pizka, 102]. His Méthode de Premier et de Second Cor (1808) gave a very thorough examination of the natural horn and its technique. Of particular interest are the comments of Domnich on the use of crooks, the hand in the bell, and transposition, which generally expound what could be considered a very traditional and standard approach to the natural horn. Two very different editions of the Méthode appeared in Domnich's lifetime. The original Le Roy edition in French, which appeared in 1808, contains extensive introductory materials on the history and technique of the horn which do not appear in Schott's French and German edition of 1832 [ibid]. This later edition does, however, contain materials which were either revised by Domnich or altered editorially; this is most clear with regard to the subject of crooks and transposition, and in itself sheds some light on the rapid changes occurring in performing techniques employed on the horn.
