Für Alina is a piece by contemporary classical composer Arvo Pärt. My teacher introduced me to this piece some time ago and it is interesting given how sparse the score is. There is no time signature and little other guidance and so it is really up to the interpretation of the performer.
I found the original score on the Music in Movement site that showcases European composers. You can see the original post about Für Alina (1976) for piano. With a bit of hunting around in the folder with the web images in it there were high resolution scans there also. I tidied those up and put them into PDF format suitable for importing into forScore or similar.

There is a great YouTube video of Arvo explaining the piece to some students. Check it out:
