GTZAN-Rhythm: Extending the GTZAN Test-Set with Beat, Downbeat and Swing Annotations

We present here the GTZAN-Rhythm test-set which is an extension of the GTZAN test-set with rhythm annotations. While there is a controversy related to the use of the GTZAN test-set for music genre classification, its audio content is however representative of real commercial music of various music genre and its audio is also already widely shared. Also, considering the various genres included in it, it provides a good balance between various types of rhythm including tracks with and without swing. We manually annotated the 1000 audio excerpts into beat, downbeat and swing annotations. We describe here this new test-set, as well as the validation of the annotations and the various uses one can make out of it (swing analysis , beat and downbeat tracking).
