The bassoon is the lowest of the four main instruments of the woodwind family. Like the oboe, it has a double reed. The reed is attached to a curved metal mouthpiece called a "crook" or "bocal" which is joined to the main part of the instrument. This consists of two parts called ‘bass joint’ and ‘wing joint’ (or ‘tenor joint’). These two are joined at the bottom by a U-shaped piece called the ‘boot’. At the top of the instrument is the ‘bell joint’. The instrument is quite heavy. Some players have a neckstrap around their neck to support the weight, but usually they use a seat strap that connects at the bottom of the boot and the strap goes across the floor. The bassoonist then sits on that strap. The bassoon is held to the right side of the bassoonist and the top of the boot joint is usually level with the players hip. The bassoon, when played right, can sound very beautiful. The bassoon has one of the largest note ranges, going from low B flat to a high F on the top line of the treble clef. The basson can also play in tenor clef, but usually plays bass clef.
Some bassoons have a white, ivory ring round the top of the bell joint. These are German bassoons (called ‘Heckel’). French bassoons (called ‘Buffet’) do not have this ring, and also sound quite different to German bassoons. Bassoons have keys to help the player to cover all the holes, but these keys do not use the Boehm system like the other woodwind instruments. German bassoons use a system called the Heckel system, and French bassoons use the Buffet system.
Playing the bassoon
To play the bassoon, it is very important to have lots of breathing support. Like with the oboe, fast passages can be played using double tonguing (single tonguing is like saying “tu-tu-tu-tu-tu”, double tonguing is like saying “te-ke-te-ke-te-ke”). In most music, the bassoon will spend a lot of time playing a bass line, perhaps the same notes as the cello or tuba. It can sometimes sound quite amusing when playing an “um-cha-um-cha” accompaniment like in the “Dance of the Cygnets” from Tchaikovsky’s Swan Lake. It can sound very tuneful and sad as in the second movement of Rimsky Korsakov’s Sheherazade. Listen to the opening of Stravinsky’s Rite of Spring where it plays some quite high notes to fool people that it is the Cor anglais. Prokofiev uses the bassoon for grandfather’s tune in Peter and the Wolf. Also, to play the bassoon a player need long fingers because the bassoon's keys and holes are quite wide.
The holes are drilled in at an angle so that the upper register is not overblown and produces an unpleasant sound. Whisper Keys are also invented to prevent overblown. The bassoon is known for its reedy sound. Its upper register is shrill and sometimes scary. Middle register could be used for lullabyes because of its majestic and soothing tone. Its lower register is deep, dark, and could be used for scary movies and such.
History and repertoire
The bassoon developed from a Renaissance instrument called the curtal or dulcian. These were double reed instruments which often played with shawms. In the Baroque period the bassoon became popular as an instrument to play the bass line, perhaps playing the same as the cello. In the late Baroque period composers like Antonio Vivaldi wrote concertos for bassoon and orchestra. Some more famous bassoon concertos include one by Mozart, and in more recent times by Peter Maxwell Davies.
In some pieces with a large orchestra a contrabassoon is used. This plays an octave lower than a bassoon, taking it right down to bottom B flat on the piano. Some contrabassoons are made to play a note lower, i.e. the very lowest note of the piano (A). One might expect to see the contrabassoon sticking up high above all the other instruments in the orchestra, but in fact the tube keeps doing U-turns, making four parallel rows of tubing. They are usually made with the bell pointing downwards. The weight is supported by a peg to the floor.
The contrabassoon adds richness to the sound of a full orchestra. Listen carefully for the contrabassoon in the hymn-like introduction to the last movement of Symphony no 1 by Brahms. It can be clearly heard, growling away, in the opening of the Piano Concerto for the Left Hand by Ravel.
