The success of the film “The Fabulous Destiny of Amelie Poulain“, is also on the soundtrack of the French minimalist composer Yann Tiersen. In particular, “La valse d’Amélie” is a song that recalls the style of Eric Satie, with a melody accompanied by a few notes. The song is composed for piano, but it is very nice also played with the guitar, so try it with the tab that you point out, after you have listened to the video.
I also have written a romantic waltzes for classical guitar as “La valse d’Amélie“, and I played it with a sympathetic orchestra, it’s named “Play the Love“. Thank you if you listen!
