I'm lost and new to this ^^

Hello so i read a manga, it started with a girl playing bass in a park or at least a public area and she remembering her mom who was in a band and died and then she was alone with her older sister taking care of her, it only had 1 chapter back then so i'm sorry if i can't give anymore details but i was very interested and forgot the name so if anyone can give any good suggestion it would be highly appreciated thank you
