Crazy clarinet players that play a bunch of instruments love to play the contra alto clarinet and when their teacher gives them some music for it, they get VERY excited.
Contra alto clarinets are reed instruments. A reed is a piece of plastic or bamboo that vibrates when air goes over it and it creates sound. A reed is kind of like one of those sticks doctors put on your tongue.
Since the instrument is so tall, you have to sit on two chairs or even a stool sometimes. It makes you feel powerful like a king or queen. You dominate the whole band.
