Automatic classification of music genres is an inherent field of music information retrieval research. Nearly all state-of-the-art music genre recognition systems start from the feature extraction block. The extracted acoustical features often could be correlated or/and redundant, which can course various difficulties on the classification stage. In this paper we present a comparative analysis on applying supervised Feature Selection and Feature Space Transformation algorithms to reduce the feature dimensionality. We discuss pro and contra of the methods and weigh the benefits of each one against the others.
