Black Winds is a term used to describe a type of wind ensemble, which is a group of musicians playing woodwind instruments. The two main instruments in a Black Winds ensemble are oboes and clarinets. Oboes are five-letter woodwind instruments that produce a distinctively bright and reedy sound. Clarinets are nine-letter woodwind instruments that produce a mellow and warm sound. Together, these two instruments create a unique sound that is often used in classical music.
