Melodic Similarity through Shape Similarity

  title={Melodic Similarity through Shape Similarity},
  author={Juli{\'a}n Urbano and Juan Llorens Morillo and Jorge Morato and Sonia S{\'a}nchez-Cuadrado},
We present a new geometric model to compute the melodic similarity of symbolic musical pieces. Melodies are represented as splines in the pitchtime plane, and their similarity is computed as the similarity of their shape. The model is very intuitive and it is transposition and time scale invariant. We have implemented it with a local alignment algorithm over sequences of n-grams that define spline spans. An evaluation with the MIREX 2005 collections shows that the model performs very well… CONTINUE READING
