I have small hands and I can't stretch the second chord [F-A-Db-F] of the second measure, which appears several times more.
You are right, Czifra777, it's Ab, sorry for my mistake in the post. But it continues being true that I can't stretch fingers 2 and 3 enough to play Ab-Db. Thanks a lot for your assistance.
Yes, Rach3, I think I'm reading the chord right: [F-Ab-Db-F], and I can reach only any 3 of the keys, but not the 4 ones. What F do you think could be omitted? Very kind of you for trying to help.
Thanks a lot for you kind contributions. No, definitively I don't reach the complete chord. I decided for the moment to omit the low F, so as to play the reduced chord [Ab-Db-F]. In so doing I think the melody hold its character acceptably. The idea of rolling seems good, it deserves more attention. Kind regards.
