Beijing Opera Percussion Instrument Dataset

The Beijing Opera percussion instrument dataset is a collection of audio examples of individual strokes spanning the four percussion instrument classes used in Beijing Opera (Jingju, 京剧).

Beijing Opera uses six main percussion instruments that can be grouped into four classes: 

  1. Bangu (Clapper-drum) consisting of Ban (the clapper, a wooden board-­shaped instrument) + danpigu (a wooden drum struck by two wooden sticks)
  2. Naobo (Cymbals) consisting of two cymbal instruments Qibo+Danao
  3. Daluo: Large gong
  4. Xiaoluo: Small gong

Audio content

The dataset provides audio examples for each of these instrument classes. The number of examples is shown in Table 1.

The audio examples were recorded under studio conditions by Mi Tian at the Centre for Digital Music, Queen Mary University of London, UK in September 2013 using an AKG C414 microphone. The audio was sampled at 44.1 kHz and stored as 16 bit wav files. The instruments were played by Ying Wan of the London Jing Kun Opera Association. Unlike some instruments that can be tuned, these percussion instruments are made from metal casting. Thus, there can be subtle timbral differences even across different instruments of the same kind. For each of these instruments, we used 2-3 individual instruments to record the samples, hoping to achieve a better timbre coverage. Further, audio samples were recorded using different playing techniques for each instrument. 
 
The dataset can be used for training models for each percussion instrument class.
