Theoretical Aspects of Music Definition Language and Music Manipulation Language

As there is an increase in the amount of on-line music and digital albums, the way of express the music has become more and more important nowadays, so it can be used in several Music Information Retrieval tasks. For example, the music search engine and the plagiarism detection tool. From the existing symbolic approaches, there are a lot of music notation and relevant theories so the musician can understand and follow easily. Thus, we need to build a theoretical system for our proposed coding scheme, naming Music Definition Language and Music Manipulation Language. Therefore, this paper is focused on some of the important theories that derived from MDL and MML. After the theoretical analysis and practical discussion, we have showed the relationship between the proposed coding scheme and the existing audio or symbolic formats. These proved the feasibility of using the new coding scheme for those MIR tasks.
