Formalism is good, you can see what genre of music it is at a glance, and then it is easy to analyze. As for harmony, it is enough to simply know the characteristics and temperament commonly used in each era.

When taking the postgraduate entrance examination, the harmony problem is only to fill in four harmonies for the melody of two sentences, which has nothing to do with the music. The problem of musical form is to analyze a piece of music completely and mark its structure, key harmony and creative characteristics. I hope this will make you understand ~ ~

Also, no one will calculate the harmony one by one when analyzing a piano piece. Too much trouble! If the form is good, you can directly find the important harmony, and then just look at those few.

In addition, upstairs, it seems that the piano major in our school requires to master all the close relationships ~ ~ Is it different from place to place? Please also advise me.

If you really want to talk about the harmony part, I'm afraid it's very deep. After learning the whole Ben Posobin, I have mastered all the classical harmonies, but I still don't know what to say when I see the impressionist piano music. Romantic people often tear a harmony apart in a bar or a few beats, and there is nothing in it. If you still want to see Modern Times, hey hey. ...

In short, I suggest you study the form well ~ ~ Those classic piano works are really profound ~ ~
