 Contrabass oboe

The contrabass oboe is a double reed woodwind instrument in the key of C or F, sounding two octaves or an octave and a fourth (respectively) lower than the standard oboe.Recent research, in particular that by oboe historian Bruce Haynes, suggests that such instruments may have been developed in France as part of an original attempt to maintain the complete family of double reed instruments when the oboe was created from the shawm.
