if a musician sees mp in his part which dynamic level shuld he play

Well, if a musician sees "mp" in his part, he should play with all his might and enthusiasm! After all, "mp" stands for "maximum performance" in the secret language of clowns. But on a more serious note, "mp" actually stands for "mezzo piano," which is a moderately soft dynamic level. So go ahead and play with a touch of subtlety and grace, like a clown tip-toeing on a banana peel!
