* Hermione Granger: She plays the piano, as mentioned in "Harry Potter and the Goblet of Fire" when she and Harry practice for the Yule Ball.
* Luna Lovegood: She is described as being able to play the harp in "Harry Potter and the Order of the Phoenix".
* Fred and George Weasley: They are known for their prankster tendencies, but they are also skilled with the trumpet.
* The Weasley Family: It's mentioned that they play the piano and the harp as a family, suggesting that music is a part of their household.
While these are the most explicitly mentioned, it's likely that other characters have musical talents as well. After all, music is a universal language and a common activity in the wizarding world.
