Both of my pinky fingers are incredibly skinny and slightly crooked. I don't like pushing keys with them on piano because it feels weird and strange. How can I strengthen/fatten up my pinky so its stronger and doesn't feel awkward when I play?
When I first started playing piano, the keys felt SO weird to me. Now, I kinda teach some basics to a few people and they say it works. So you just need to practice using your pink finger more. Remember, you don't have to be at the piano to practice. You can tap your pink finger anywhere you are. Just practice.
(My pinky fingers are crooked too but its fine!)
