The melody in music can only be assessed by the assessor’s emotions so it can only be subjective and cannot be expressed in standardized numbers. Therefore nobody can know for sure if two songs are plagiarized or not. In this paper, we attempt to realize a plagiarism analysis system of musical content that can provide judging grounds for plagiarism – usually analyzed in consideration of human emotions - using IT technology. To protect music copyright, both knowledge of music and IT technology is compulsory to create a music plagiarism analysis system. First, by understanding factors of the musical content and analyzing plagiarism between two separate but similar voices. We tried to invent a system that measures the level of similarity. For this we considered the digital music factors for the analysis of voices and searched for methods to use IT technology for judging plagiarism. For an efficient analysis of plagiarism, we utilized the music string provided by JFugue, and designed a plagiarism analysis system for musical content and proposed an abstract syntax tree (AST).
