Here is a string quartet arrangement of Joe Hisaishi's "Summer," which serves as the main theme for the movie Kikujiro, a 1999 Japanese film directed by Takeshi Kitano. This arrangement comes with a score and a set of parts for 2 violins, viola, and cello. The original piece really embraced the movie's light-hearted atmosphere, which I really wanted to replicate in this arrangement with lots of pizzicato and syncopated rhythms. I know it says for Advanced Intermediate, but as long as you know how to play up to 4th position (for first violin), and you are comfortable with syncopated rhythms and some 16th-note runs, you should be fine.
