Abstract: Content-based music retrieval gains more and more significance in recent years，and a number of retrieval methods have been proposed.Most existing methods use only one or two significant features to represent a piece of music.Different from the existing methods，in this paper，a new method is proposed that represents a piece of music by a feature matrix generated from its spectrogram，thus the similarity between the query and any candidate music file in the database is evaluated by the similarity of two matrices.Experiments show that this method can achieve satisfactory retrieval performance.

Key words: acoustic music, spectrogram, matrix similarity, content-based music retrieval
