There is a whole family of clarinets, a popular woodwind instrument. There are about a dozen different sizes and tones for these instruments, with some much more rare than others. Clarinets are played with a reed in the mouthpiece and have the most range out of any woodwind instrument. Depending on the skill of the musician, a clarinet can go four octaves in range. The reed is made from a special type of cane, called the Arundo donax.
