Musical rhythm: Onsets/intervals of seven music corpora

These files contain onset/interval data (in ms) from 7 music corpora covering different musical styles (Western & non-Western), 2 of solo- and 5 of multi-instrument performances. The data are suitable for analyses of rhythm (they include mainly percussion/keyboard instruments with crisp onsets). File "METHODS4IntervalData_processing of musical corpora.pdf" provides details on how onset data were obtained & how to visualize rhythm with the Matlab code provided in folder "MatlabCode_RhythmVisualization". Files & data: 1. "IntervalData_CubanSalsa_corpus.mat": Cuban Salsa & Son, multi-instrument music, original recordings from the publicly available Interpersonal Entrainment in Music Performance (IEMP) corpus (https://osf.io/37fws/). Two variables: "CubanSalsa_intervals_ms": vector of onset-onset intervals, instruments separated; "CubanSalsa_INSTRUMENTSCOMBINED_intervals_ms": vector of onset-onset intervals for all instruments combined (for details, see file "METHODS4IntervalData_processing of musical corpora.pdf") 2. "IntervalData_MalianJembe_corpus.mat": Malian Jembe, multi-instrument music, from IEMP corpus (https://osf.io/y5jxm/). Two variables: "MalianJembe_intervals_ms": onset-onset intervals, instruments separated; "MalianJembe_INSTRUMENTSCOMBINED_intervals_ms": onset-onset intervals, instruments combined 3. "IntervalData_NorthIndianRaga_corpus.mat": North Indian (Hindustani) Raga, multi-instrument, original recordings from the IEMP corpus (https://osf.io/3cmg4/). Two variables: "NorthIndianRaga_intervals_ms": onset-onset intervals, instruments separated; "NorthIndianRaga_INSTRUMENTSCOMBINED_intervals_ms": onset-onset intervals, instruments combined. 4. "IntervalData_TunisianStambeli_corpus.mat": Tunisian Stambeli, multi-instrument music, original recordings from the IEMP corpus (https://osf.io/qaxdy/). Two variables: "TunisianStambeli_intervals_ms": onset-onset intervals, instruments separated; "TunisianStambeli_INSTRUMENTSCOMBINED_intervals_ms": onset-onset intervals, instruments combined. 5. "IntervalData_UruguayanCandombe_corpus.mat": Uruguayan Candombe, multi-instrument music, original recordings from the IEMP corpus (https://osf.io/4q9g7/). Two variables: "UruguayanCandombe_intervals_ms": onset-onset intervals, instruments separated; "UruguayanCandombe_INSTRUMENTSCOMBINED_intervals_ms": onset-onset intervals, instruments combined (see above). 6. “IntervalData_PianoBach_corpus.mat”: Western piano (Bach) solo performances, from MAESTRO dataset (https://arxiv.org/abs/1810.12247). One variable: "PianoBach_intervals_ms": onset-onset intervals. 7. “IntervalData_PersianZarb_corpus.mat” Zarb solo playing by 5 performers from commercial recordings. One variable: "PersianZarb_intervals_ms": vector of onset-onset intervals. 8. Folder "MatlabCode_RhythmVisualization": "plotRatioHist.m" plots histogram of dyadic interval ratios, "plot_FlowerShapedRasterPlot.m" plots sorted raster plots of dyadic interval pairs.

本数据集包含来自7个音乐语料库的起音（onset）/间隔数据（单位：毫秒），涵盖西方与非西方多种音乐风格，其中2个为独奏表演语料库，5个为多乐器合奏表演语料库。该数据集适用于节奏分析，数据主要包含起音清晰的打击乐与键盘乐器相关信息。文件《METHODS4IntervalData_processing of musical corpora.pdf》详细说明了起音数据的获取方式，以及如何使用"MatlabCode_RhythmVisualization"文件夹中提供的Matlab代码实现节奏可视化。
