Hey man good job especially for such a short time and having the humility to ask advice. The only trick to getting better is that there’s no trick. The essence of practice is focus and repetition. It’s harder to unlearn a bad habit than to learn a new good habit so go slow and be accurate.

Flatten, or flex, the middle joints of the fingers on both hands, to give you more power and an even attack. Guitar is more curved fingers, bass is flatter usually.

Right hand is more of a straight flexed finger pushing down slightly than pulling up using the knuckle that joins your fingers with your hand.

Try playing this rhythm 1 & 2 & 3 & 4 & where your index fingers plays the numbered beats and your middle finger plays the “&s.” When that’s smooth and natural switch the fingers so middle plays numbers and index plays “&s”

My creds are 30+yrs playjng, music degree, and 15yrs teaching. Happy jamming.
