The oboe is an instrument in the woodwind instrument family, putting it in the same class as the clarinet and the flute. It often features a certain type of wood called grenadilla, as well as silver keys. The most notable feature of an oboe is its double reed, which helps give it a very distinct and clear sound that you won't get with other woodwind instruments. Wind ensembles and orchestras often feature the oboe, wherein they tend to always play the tuning note for the entire group. This is because the Oboe is the instrument least susceptible to its tuning being affected by humidity or other climatic conditions.
