The clarinet, flute, oboe, bassoon, coranglais, saxophone and chalumeau are wood wind instruments. The most popular wood wind instruments are the flute, clarinet, oboe and bassoon.
Most of these instruments are double reed instrument except for the clarinet and the saxophone and the flute does not have a reed. The clarinet has many keys compared to the flute and oboe. It is also one of the easiest wood instrument to learn. The oboe and bassoon are the hardest to learn. The clarinet transposes.
For example, the fingers put on the lower part of the clarinet produce the Bb note, the F note is also produce at the same position if the clarinet is blown harder.
The woodwind family primarily is made up of the flute, oboe, clarinet, and bassoon. The flute as no reed and is played off to the side. The oboe, clarinet, and bassoon all require reeds to be played. The bassoon and the oboe both have double reeds and the clarinet only has one.
Saxophones sometimes supplement the woodwind section and also have a single reed mouthpiece. In a symphony, there is usually a standard clarinet, and there is a possibility of a bass and e-flat clarinet. All three types of instrument can be played by a clarinet player and all three make distinct sounds and music.
