CBF-periDB: A Chinese Bamboo Flute Dataset for Periodic Modulation Analysis
We present CBF-periDB, a dataset of Chinese bamboo flute performances for ecologically valid analysis of periodic modulations in context. The dataset contains monophonic recordings of four types of isolated playing techniques and twenty expert full-length performances of classic Chinese bamboo flute pieces. Four types of playing techniques---vibrato, tremolo, trill, and flutter-tongue---are thoroughly annotated by the players themselves. These techniques are also referred to as periodic modulations due to their periodic patterns in the time-frequency domain. All recordings and annotations can be downloaded from c4dm.eecs.qmul.ac.uk/CBFdataset.html.
