Set of complex rhythmic tasks exhibiting LRC.

The exponents shown in the table were obtained using DFA and the exponents were computed via the PSD. In the set the complexity of rhythmic drum patterns decreases from tasks no. to . In tasks no. we analyzed real drum recordings that are taken from popular music songs, the two drummers are different persons. Tasks no. were performed by a third (different) drummer, where no. consisted of a short rhythmic pattern (that included beats and off-beats) repeated continuously by the drummer. We analyzed the fluctuations of both beats and off-beats (no. ) of the pattern and in addition we considered the fluctuations of the beats (task no. ) and off-beats (no. ) separately. See main text for a description of and .本表所列的指数通过去趋势波动分析（Detrended Fluctuation Analysis，DFA）获得，并经由功率谱密度（Power Spectral Density，PSD）计算得到。本数据集内，节奏鼓组模式的复杂度随任务编号从任务no. 至任务no. 依次递减。在任务no. 中，我们分析了取自流行音乐作品的真实鼓组录音，本次实验使用了两位不同的鼓手。任务no. 至任务no. 由第三位（不同的）鼓手完成，其中任务no. 包含一段由鼓手持续重复的简短节奏模式（该模式涵盖正拍与反拍）。我们分析了该模式中正拍与反拍（任务no. ）的波动特征，此外还分别考察了正拍（任务no. ）与反拍（任务no. ）各自的波动情况。关于任务no. 与任务no. 的详细说明，请参见正文内容。
