I don’t understand the arrangement, but I can understand that the arrangement is monotonous. Monotonous is what it means in the dictionary, and it has nothing to do with the key. For example, it takes a lot of threads to weave a piece of cloth. If there are fewer threads, wouldn't it be thin? If the threads are better, you can embroider some flowers or something. This involves the use of techniques such as harmony and orchestration. But it does not mean that the more complex the arrangement, the better. It must be just right, otherwise it will destroy the beauty of the work. For example, bead curtains are better left blank.
