On The Digital Music Composition

In 1946, the first computer was made successfully. It announced that a time began. The computer technology developed through several dozens years, passed through the electron tube, the transistor, the integrated circuit, the large scale integrated circuit and the ultra large scale integrated circuit to intelligent computer today. Its application scope also from the initial pure digital computation grew into multipurpose, for example, the work, multimedia, the network and so on. At present, so long as the personal computer has the corresponding software, it can do anything. When computer and music met, a new thing - digital music produced. Digital music is named the computer music. Computer music is making music by computer, and as well as this kind of music. The meeting of computer and music might trace to 1982, the first MIDI standard formulation, to present, also has already passed through 26 years. It become more and more advanced, the application scope is more and more widespread. From the earliest sole MIDI synthesis, to the digital audio frequency, to the soft sound models, at last arrives the multi-track audio recording and mix the sound again. The computer may simulate the any sounds in nature, also can create sounds that nature can't make. It enriched music sources and materials. It is easy to see that the influence to music creators by digital music is huge in develops of digital music. Music creators may record the inspiration fast, and debug each kind of interesting sound. Digital music already became a more and more important method in music creation and the music manufacture, even becomes some composer's essential creation method.Compare with the realistic situation narrates above, at present; there were few people to research what were brought to the music creation by digital music systematically. In the bookstore, we may buy many books about the digital music; also saw many music amateurs to go to purchase. However, these books are embark from the pragmatism, talk about a software, or a technology only, but can't observe digital music itself from a higher angle of view. So, the paper what you are reading doesn't talk about a software specially, or seek one kind of technology, but make a summary of the present situation research, studies its function and the influence. In another word, what has brought for music creation by digitization? This thesis has no precedent.The article's first three chapters will explain the details of the digital music's development. Including formed process and last technology, branches, rationales, realizing methods, and so on. After that, in the fourth chapter and fifth chapter, the article would analyses the influences which brought to composing music by digital music. In the past time, the people esteem the digital music. However, not only this article must talk about the promo table actions, but also opposite actions. These viewpoints are pointed out the first time in history.
