The bassoon is a double-reed orchestral woodwind.

Introduction

The bassoon is a double-reed aerophone , and is the largest of the standard orchestral woodwinds . Although called bassoon in English, it is called fagotto or fagott or fagotte in other European languages, possibly because its construction reminded someone of a bundle of wood.

The instrument

The bassoon is constructed of 5 separable parts. The mouthpiece is just two pieces of reed bound together - hence the term double reed - set into a thin metal crook or bocal that leads the air into the main body of the instrument. In the tenor joint the air travels down toward the butt , where it makes a sharp turn back upward to travel through the bass joint and the bell , which ends above the players head.

The total length of the bassoon, including reed and crook, is over 9 ft. The large size of this woodwind means that its finger holes have to be bored through the wood at an angle to make it playable; otherwise they would be too far apart for the fingers. These angled holes have a strong effect on the timbre of the instrument; the upper harmonics of each note are stronger than the fundamental , giving the bassoon its strongly "reedy" color.

The double bassoon or contrabassoon is even larger and longer; the air doubles back yet again to a downward-facing bell, and the instrument sounds an octave lower than the regular bassoon. Its timbre is rich and deep, and not so reedy.

Like the oboe, the bassoon has a conical bore , so it overblows at the octave .

Different bassoons may have different key systems, and instruments are highly individual. Players of brass, strings, or other woodwinds don't like to switch instruments, but in an emergency they can do it if they have to. A bassoon player simply can't; the instruments are too individualistic.

Written range of bassoons

The bassoon sounds as written. The contrabassoon, written in the same range, sounds one octave lower.

History

The bassoon evolved during the 17th century from the curtal. Early bassoons were made from a single block of wood.

Most early woodwinds had holes covered by the fingers rather than keys . But the bassoon is quite large for a woodwind instrument, and its holes must be a certain distance apart in order to give a proper scale. To make things a little easier on the fingers, the holes are bored into the wood at an angle, but keys are still necessary to make the instrument reasonably playable. The bassoon had some keys already by the early 1600's, and more were gradually added to make the fully keyed modern instrument. In the 19th century various German instrument makers experimented with different systems of keys; the system perfected by Heckel became the most popular, but (unlike most other woodwinds) there are still different key systems and different fingering methods in use.

Repertoire

    If you would like to hear bassoons, here are some suggestions for music that should be easy to find.

  • Igor Stravinsky's Le Sacre du printemps ("Rite of Spring") begins with a bassoon solo in the high register of the instrument.
  • Dukas' L'Apprenti Sorcier ("The Sorcerer's Apprentice" - yes, the same one that Mickey Mouse popularized) may be the most well-known bassoon tune.
  • The second movement of Rimsky-Korsakob's Sheherezade includes a couple of extended bassoon solos.
  • If you'd like to listen to a bassoon concerto, those by Vivaldi or Mozart may be easiest to find.
  • The grandfather in Prokofiev's Peter and the Wolf is a bassoon.

Practical information for composers and arrangers

The bassoon is a nontransposing instrument, with written parts that switch freely from bass to tenor and occasionally treble clef . It is not as agile as the other woodwinds, but can handle moderately fast passages.

The bassoon is the bass of the woodwind section. In orchestral music, it sometimes doubles the cello part. Its distinctive timbre is also useful for solo work, and has been used effectively to evoke every mood from comical to dreamy.
