Temporal Pyramid Pooling Convolutional Neural Network for Cover Song Identification

Cover song identification is an important problem in the field of Music Information Retrieval. Most existing methods rely on hand-crafted features and sequence alignment methods, and further breakthrough is hard to achieve. In this paper, Convolutional Neural Networks (CNNs) are used for representation learning toward this task. We show that they could be naturally adapted to deal with key transposition in cover songs. Additionally, Temporal Pyramid Pooling is utilized to extract information on different scales and transform songs with different lengths into fixed-dimensional representations. Furthermore, a training scheme is designed to enhance the robustness of our model. Extensive experiments demonstrate that combined with these techniques, our approach is robust against musical variations existing in cover songs and outperforms state-of-the-art methods on several datasets with low time complexity.

Intonation in Iraqi Musical Melodies

This paper deals with intonation in Iraqi musical melodies (MMs). As such, it aims to analyze the intonational patterns in the Iraqi music. The main musical melodies in the Iraqi music are Rast, Dasht, Hijaaz, Kurd, and Bayaat. In this vein, the current study attempts to answer the following questions: the current paper attempts to answer the following questions: (i) What are the intonational patterns of Iraqi MMs? And (ii) What is the additional function of intonation in MMs? In the light of these questions, the corner hypothesis is that Iraqi MMs have their own specific definable intonational patterns. On the basis of the analysis, it is concluded that intonation can be a useful tool for analyzing musical variations in the basic Iraqi MMs. Moreover, musical intonation, which is the task of musicologists, is accompanied by phonological intonation to create the final form of the melody. Finally, in addition to previous functions of intonation, such as grammatical, semantic, and so on, intonation has a new one, namely ‘musical function’ because it gives music special effects and evaluations.
