Classic Wiki Oboe

The oboe is a double reed, woodwind instrument with a conical bore. A cap, as in the clarinet, does not protect the reed.

The history of the oboe can be traced but the exact date of its appearance is difficult to identify since its evolution has been gradual. Also obscuring the emergence of the oboe is its name that is a corruption of hautbois. Historically, the oboe descended from the shawm family that had divided into the hautbois and gros-bois: the high woods and great woods. At some stage oboe and hautbois were synonymous so one can only guess at the oboe's appearance as an instrument in its own right but sometime during the eighteenth century might not be too far off the mark.

The principal soprano double-reed woodwind instrument. It consists of a slender bore of hardwood, c 59 cm long and in three sections, which open out to form a moderate bell. The reed is formed of two hollowed-out blades of thin ‘cane’ bound face to face to a narrow tapered metal tube (a ‘staple’). At their free ends, the blades are scraped down to a feather edge: placed between the lips and blown through, they vibrate together, transmitting bursts of energy to the air column in the body.
