Click = Zoom in | Double-Click = Zoom out


After the end of the classical period the frenchhorn had emerged as the main instrument from the large family of various horn instruments. But then there was a lack of a real conical soprano instrument. The invention of the Perinet valves at the beginning of the 19th Century in France lead to the devolpment of a “cornet à piston”. The key was A and Bb, moreorless the today’s main trumpet key. This type became very popular and spread fast. Trumpet players soon became also “Cornetists”.
In Germany and Austria cornets also have been built with rotary valves.

Model information
