Multiscale Signatures of Beatles Songs in a Cover Song Task

While there are several Music Information Retrieval (MIR) classification and comparison tasks, this work focuses on the cover song task. Given a particular piece of music, the goal of the cover song task is to find all the different recordings of the given song by a variety of artists in a set of music. For this work, our dataset is a collection of songs by the Beatles. Our approach begins by building a novel multiscale signature for each song that captures repetitive structure at several scales, while also being of a manageable dimension. We then apply a metric to this representation space of song signatures, allowing for fine-tuned comparison between songs. This multiscale approach differs from those in the literature that largely consider single-scale, single-feature representations.
