I'm trying to play, with my right hand, A4 E3 D3 E3 C3. The score suggests the 5th finger on A, and the three first fingers on C, D, E, that is 5,3,2,3,1. I'm able to play it comfortably but I notice that my fourth finger is curled all the way towards the inside of my hand. This intuitively seems like a terrible habit, but when I try to keep my 4th finger extended, it creates a ton of tension and it presses on F.
What should I do?
