Oboe: An Overview — Orchestre Métropolitain

“The oboe is normally made of grenadilla, a very dense wood, and its keys are made of metal. Like the English horn and bassoon, one produces a sound with an ancient and very peculiar invention: the double reed! The slightly nasal yet alluring sound of the oboe originates from two thin pieces of bamboo vibrating against one another when the oboist blows through the reed.”
