In 1877 the workshop of Adam and Wilhelm Heckel produced a patented model with a chromatic range of C1–G3. What set this contrabassoon apart from previous models was its ease of response and its great agility, which enabled it to assert itself over the other contrabass instruments of the time. Richard Wagner was one who was convinced by the quality of its tone, using it in his Parsifal (1882).
At the beginning of the 20th century the contrabassoon was further improved by Wilhelm Heckel: the range was extended down to Bb5 (or, with an appropriately long bell, to A5), and up to C4. In 1901 he created the prototype of the modern contrabassoon, which boasted a full and mellow timbre coupled with great technical agility. The firm of Heckel remains one of the leading manufacturers of bassoons to this day.
In France the firm of Buffet-Crampon produced a French model in 1906 which differs mainly in terms of the keywork.
Thanks to these technical improvements, the contrabassoon, which had hitherto been confined to the reinforcement of the bass voice, was now given challenging new tasks as a solo instrument. In addition it has grown in popularity since the 20th century because of its sound characteristics and has found its way into chamber music, too.
In today’s orchestra the contrabassoon plays those parts that were written for the contrabass sarrusophone, a widely used instrument that had been scored for particularly by composers in France and Spain (Camille Saint-Saëns, Claude Debussy and Maurice Ravel, for example). Production of the contrabass sarrusophone ceased in the 1830s, although it is still found in music for wind band in France, Spain and Italy.
