What is this quintet from a Swedish movie?

[Theodore S.]

Hello everyone,

A few years ago, I saw this beautiful but rather uncomfortable Swedish period drama film called "Den Goda Viljan" ("The Best Intentions", based on the relationship of Ingmar Bergman's parents), and early on in the film, there is a scene in which a quintet for clarinet, violin, viola, cello, and piano, is played at a dinner party. The scene can be watched here starting at exactly 9:00: https://www.youtube.com/watch?v=OR_3XRIgiNY

Does anyone know what this piece is? It sounds like it's from the late classical era, perhaps late 18th/early 19th century, but I honestly have no idea who wrote it or where it's from. I have a feeling it might be an instrumental arrangement of an operatic number or a song, since I could find no such quintet on IMSLP which would match the style, time period, or musical content. It kind of sounds like something Mozart would have written. Unfortunately the end credits don't provide any info on this piece, and IMDB mentions nothing about it.

What do you think? It is a rather lovely piece to my ears.

(Edit - feel free to move this to "Composers and Music" if it feels inappropriate for this channel.)

The end-credits mention 'Stefan Nilsson' under the category of music for the film. Is it possible that the music was specially composed?

It's very possible. But I am a bit unsure of this is because when I look up the film music tracks for this movie (which can be found on YouTube, and which were released on a CD of other soundtracks by Nilsson), this piece was not one of them. Of course, that doesn't mean it wasn't composed by Nilsson, as it has happened before that releases of OSTs omit some tracks from the film score. Besides this, the quintet only appears once in the film, and the rest of the soundtrack - beautiful as it is - is in a different style from this piece, quite minimalist in style.

Later in the film, several scenes make use of other older pieces of music, mostly German and Swedish hymns (since part of the film is set in church). All of this made me think the quintet might be something older, but I don't really know.
