👉 A contrabassoon is a type of string instrument that is commonly used in orchestral and chamber music performances, particularly for soloists who play the bassoon or the contrabassoon. It was originally developed as an addition to the horn section, but it has since become a more versatile instrument in its own right. The contrabassoon typically consists of two strings attached at each end, with each string having four fingers or a pair of hands for plucking and strumming.
