Denner and his son Jacob improved the chalumeau creating a new instrument, the clarinet. Denner added two extra keys to the chalumeau increasing the instruments range by 2 octaves. He improved the mouthpiece and also the bell (end of the instrument). Mozart was the first composer to use the clarinet in a symphony. The chalumeau comes from the Latin word "calamellus" meaning reed.
