Modeling Melody Similarity Using Music Synthesis and Perception

Melody similarity in music is a perception of listeners based on cognitive method. Thus, the algorithms should be based on perceptually oriented computational model. We have used computer generated synthesized tune of popular song and its variations to understand similarity notion. We have generated variations of a tune by changing musical scale or relative duration of notes or notes itself and combination of them. The proposed approach to calculate similarity relationship between two tunes will be useful to model the melody similarity notion for various applications such as QBH (Query by humming), music classification and retrieval, music plagiarism etc.
