摘要：This paper introduces an interactive system of sight-singing and ear-training which combines the technology of single chip microprocessor (SCM) with learning music. It contains the functions of scanning keyboard, reading the key value, interruption service, reading file and displaying file. In order to strengthen the commonality and practicability of the system, SD card is used to store the materials and the ZNFAT32 file system is transplanted to organize the materials in the form of file directory. This interactive system can recognize and perform music automatically for the users and play significant role in education and entertainment.
