Haha, Bruce’s vicissitudes of life are not enough, it has to be sad. It seems like there really isn’t anything particularly famous. Mito's moody is pretty good. I usually listen to good tunes and play them on the harmonica. Hayao Miyazaki's Castle in the Sky and Dreamy CHILD are both melancholy and sad, and they are not difficult either. Try it, the harmonica really doesn't seem to have a sad style. but. Shikong pays attention to the rhythm, it will be very interesting when you play it
