Scoring system for piano grading test

Abstract

The present invention provides a scoring system for the piano grading test. After the grading scoring system receives an audio signal during the piano playing process, the system respectively scores the pitch accuracy of the audio signal, the rhythm accuracy of the audio signal, the track integrity and the timbre expressive force, and then conducts the comprehensive evaluation scoring operation. Therefore, the piano learning and grading is facilitated by the system. The grading scoring system comprises a track selection unit, a signal receiving unit, an information extraction unit, a playing scoring unit and a report outputting unit. The track selection unit is used for selecting a track for musical performance scoring. The signal receiving unit is used for receiving the audio signal during the playing process. The information extraction unit is used for extracting the playing information of the audio signal, and transmitting the playing information to the playing scoring unit. The playing scoring unit is used for comparing the playing information with the track selected by the track selection unit and calculating a scoring result. The report outputting unit is used for generating and outputting a scoring report. According to the technical scheme of the invention, the timbre expressive force is incorporated into the evaluation standard for the piano grading test.
