Samadi G. Fadaei Journal Article 2015 09 14 <strong>Purpose</strong>: To study the significance of Music Information Retrieval (MIR), the differences between text and music storage and retrieval, MIR systems’ tasks and other challenges. <strong>Methodology</strong>: Theoretical analysis. <strong>Results</strong>: There are different search engines and databases for MIR, like LastFM, Pandora and Muggle. Similarity, classification, transcription, rhythm and pitch recognition and Query-by-Humming (QBH) are the main tasks of MIR systems. <strong>Conclusion</strong>: Because of the differences between text and music qualities, text retrieval and MIR are different. To properly perform, each MIR system needs to consider: incorrect melody singing in QBH, difficulties of transcribing polyphonic music, genre’s dependency to several classes, the lack of clear sense among tags and similarities in various pieces of music <strong>Purpose</strong>: To study the significance of Music Information Retrieval (MIR), the differences between text and music storage and retrieval, MIR systems’ tasks and other challenges. <strong>Methodology</strong>: Theoretical analysis. <strong>Results</strong>: There are different search engines and databases for MIR, like LastFM, Pandora and Muggle.
