Heinrich Domnich (1767-1844) was born in Würzburg, 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.
