There are not many books on pure arrangement. Most of the literature is in English. If you want to learn by yourself, I recommend the book published by People's Posts and Telecommunications Press:

"Modern Musician's Arranger's Handbook--" An Essential Guide to Traditional Orchestral Instrumentation and MIDI Sequencing Production"

Compiled by Andrea Pejrolo and Richard DeRosa from the United States. It has been translated into Chinese. I personally think it is very classic. It comes with audio demonstrations and 33 scores. From simple to complex, but covering all aspects of MIDI music production. I wonder if you have ever been exposed to MIDI. Having said that, MIDI technology is now a must for arranging... In terms of instrumental music, being able to play Xiao Lian shows that the music foundation is good, but only knowing the piano is definitely not enough for arranging. If you have been exposed to orchestration, you should be able to understand me. meaning.

In fact, arranging music still requires years of practice and a certain amount of talent. In addition to books, I recommend you three methods:

Listen a lot, the albums you have are the best teaching materials, imitate after listening;

Find a skilled arranger to guide you, arrange Composition experience is very valuable;

If you don’t know the arranger, you can look for videos on Youtube.
