my pinky does weird stuff when i play
Never fear, this is common among a lot of players, and I have broken this habit.When playing trills or scales in pieces, keep your hand and arm relaxed. Your pinky is sticking up due to too much tension in the wrist. Once you loosen up your hand, your arm, and your wrist, this will also open doors for more power in your playing, more opportunities for dynamic contrast, and it will be significantly easier to play.
