日本泉屋博古馆所见先秦私文书——西周青铜私文书的鼎盛

在日本泉屋博古馆展藏的中国青铜器中，西周青铜私文书的数量和字数超过了商和春秋战国，不仅如此，中国考古出土的青铜铭文器字数和数量，迄今为止，也是以西周居多。西周铸造技术的提高和普及、奴隶制度的高度完善、家庭成员思想观念的转变及留传意识的增强等，是西周青铜私文书的数量、字数以及记事的范围和内容增多的主要原因。西周是青铜私文书发展的鼎盛时期。

Music, as a part of culture, has been playing an immensely important role in the com- munication between China and Japan. It is reflected in the most representative aspect of modern musical exchange between the two countries-singing songs at school (called amusing songs at school in the earlier period in China). For both of the countries, it embodies the vicissitudes that take place when we contact the western music, namely, an absorbing and digesting process of the we-stern music. But the developing orbit in this area in the two countries is different because of the diversities in social, historical, cultural and economic respects in the two countries. Now more and more attention is paid to the study of this field.
