Определение и Значение "contrabassoon"

What is a "contrabassoon"?

A contrabassoon is a large woodwind instrument that plays an octave lower than the bassoon, making it the lowest-pitched instrument in the woodwind family. It has a long, coiled body and uses a double reed to produce a deep, resonant sound. The contrabassoon is played by blowing air through the reed and pressing keys to cover holes along its length, which changes the pitch. It provides a powerful, rich bass tone and is used in orchestras to add depth and support to the lower range of the music.
