The oboe is a type of double reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic, resin, or hybrid composites. The most common oboe plays in the treble or soprano range. The regular oboe first appeared in the mid-17th century, when it was called a hautbois. This name was also used for its predecessor, the shawm, from which the basic form of the hautbois was derived. Major differences between the two instruments include the division of the hautbois into three sections, or joints and the elimination of the pirouette.
Today, the oboe is commonly used as orchestral or solo instrument in symphony orchestras, concert bands and chamber ensembles. The oboe is especially used in classical music, film music, some genres of folk music, and is occasionally heard in jazz, rock, pop, and popular music. The oboe is widely recognized as the instrument that tunes the orchestra with its distinctive 'A'. A musician who plays the oboe is called an oboist.
