The kloo horn.
The kloo horn was a double-reeded wind instrument, larger than a Slitherhorn and a Fizzz[1] (roughly 1.5 meters tall), and one of the most commonly used instruments in the galaxy. It was considered a primary instrument for musicians specializing in the field of Jizz or Jatz. The mouthpiece of a kloo horn extended into a handheld "S" shaped body where players could use their hands to make adjustments for tone and pitch. The average kloo horn weighed approximately 1.2 kilograms. By the pricing standards used late in the Galactic Civil War, a well-kept kloo horn could be purchased for roughly 2,000 New Republiccredits.
It is possible that the kloo horn was based on the bassoon, as its size, crook, body, and manner of performance is similar to the above instrument. In truth, it was made of metal, making it more akin to a saxophone—in context, logically, the kloo horn sounds like a soprano saxophone in songs such as "Mad About Me." Also, the horn had the ability to do slides, smears, and glissandi, making it relatively similar to the trombone.
