Tchaikovsky composed a number of collections of shorter works for the Piano. This one is based on the "Waltz" (No.8) from his Op.39 collection called "Album for the Young". However it has been arranged by Jim Paterson for B-flat Clarinet and Piano, and in a more suitable key. The sheet music available for download consists of the Clarinet part and the overall Score since it is assumed that the pianist will play from the score. The original work is also available on mfiles as Waltz (Op.39 No.8) for Piano Solo.
Here is a video of Tchaikovsky's Waltz from Album for the Young (Op.39 No.8) for clarinet in B-flat and piano:
