This duet is from my book Intermediate Clarinet Duets, Vol. I.  You receive the score and the separate parts.

The Clarinet 2 part is generally easier. This duet is perfect for teacher/student, or two players of the same level of technical skill (or one player who isn't as technically advanced.) 

The book of 12 duets is also available..
