A B-flat instrument similar in sound to a trumpet. For the most part, they have been replaced by trumpets in high school bands as they save money by just having the band have a bunch of trumpets.

Used in Brass bands to produce a tight laser beam of incredibly high intensity. If used in conjunction with a shallow small bore mouthpiece it is capable of bringing down aircraft from heights of up to 50,000,000 feet.

Not to be confused with a soprano saxophone which is for pussies.
Soprano cornet brings down Airbus A380 from 40,000,000 feet overvthe Atlantic.
