What are the characteristics of music that is good at freehand brushwork but not good at realism?

Generally speaking, music is not good at imitation, because a lot of visual images and people's psychological feelings can't be imitated directly. Rousseau once said: Musicians' art is not a direct imitation of objects, but the ability to make people's minds close to the artistic conception caused by the existence of (described) objects. For example, Beethoven's "To Alice", I heard * * *, wonderful music from my ears. Is Alice a woman? Maybe. What's the image? We associate the beautiful girl image with elegant manners, gentle temperament and beautiful face. The portrait of this scene in our mind will never be specifically outlined in music. This is where music is good at freehand brushwork and not good at realism.
