The Construction Method Of Partials In Spectral Music

As a school of music whichis highly integrated natural science, spectralism composers tend to focus on the study of the sound property andthe nature of its internal structure, and paid great attention to the acoustic space Information on the time of development. With the development of the electronic acoustic technology in early 20 th century, spectrum analysis technology had replaced the human ear to achieve further explore of sound’s internal structure possibly. Composers can visually see the inclusion in each of the sound of the various components in the spectrum with the eyes, and these include the concept of crossover homophonic columns, and make it apply to creative works. And among the many acoustic instruments, the bell from sounding body structure to sound ingredients are a special kind of presence, the structure of its crossover profound issue is extremely complex, which is driven by a large number of Western musicians to study it since ancient times and creation, including Liszt, Wagner, Mahler, Debussy and Ravel. In 1980, the piece " Mortuos plango,Vivos voco " composed by the British spectrum composer Jonathan Harvey could be called a great spectral music work by using the sounds of bell. By taking this work as an example,the article has cited a wealth of knowledge of spectral music and the physical acoustics, given an analysis of the concept of partials’ structure and composition, and interpretation of crossover obtained from the organization and Construction of ways.
