As ensemble music became more popular during the sixteenth century there was increased demand for wind instruments that could elegantly negotiate the lower ranges.

Large versions of wind instruments intended for the higher registers lacked volume and agility and were often difficult to play. Various elements of existing instruments – the bass recorder’s crook and the shawm’s double reed, for instance – were combined to create the bassoon’s predecessor: the dulcian.

Dulcian

Meaning ‘sweet’ (presumably in comparison with the raucous shawm), the dulcian, standing at nearly 1 m (3 ft) high, was constructed from a single piece of wood, into which were cut two conical bores that were connected at the base. With eight finger holes and two keys the dulcian, overblowing at the octave, had a range of C to g'. At the same time, versions of the dulcian were made out of separate pieces of wood, which were then bound together, giving rise to the term ‘fagot’ because of its resemblance to a bundle of wood.

Development of the Bassoon

The dulcian was gradually developed over the ensuing centuries. Keys were added, the distribution and size of finger holes was experimented with, the wood altered, the range extended, and crook and bell redesigned. During this period, it acquired the name bassoon, probably derived from the term ‘basson’, which was often applied to bass-register instruments.

During the nineteenth century, versions of the bassoon were created by Adolphe Sax and Theobold Boehm, though neither were ultimately successful. It was Carl Almenraeder’s (1786–1846) innovations between 1817 and 1843 that led to the creation of the modern bassoon. His work was continued by J.A. Heckel and the Heckel bassoon – as it came to be known – has been adopted as the standard design.

Heckel Bassoon

At 134 cm (53 in), the Heckel bassoon, made of maplewood, is constructed of four joints, which combine for a total tube length of 275 cm (108 in). The bassoon is held at an angle with a crook enabling the double reed to sit comfortably in the player’s embouchure. With 21 keys on the standard design, the Heckel bassoon has a compass extending from Bb' to at least a' and possibly up to e''. Some composers, notably Wagner, have written for a bassoon that can play a low A', but this requires an extra-long bell and an additional key that most players believe destabilizes the instrument too much to become a standard feature.

Although the Heckel system is generally accepted as standard, it has competition from a French design. The Buffet bassoon was created in the 1830s and has a much softer, more singing tone. This is principally due to a different wood – dark rosewood – and a different key and fingering system. It remains in use in France and Spain, and was the instrument many composers had in mind when writing orchestral music, including Giacomo Puccini (1858–1924), Claude Debussy (1862–1918)...
