"Synthetic Executable Companion: Toccata and Fugue in D Minor (BWV 565) Simulator and Dataset"

"This dataset and simulator model J. S. Bach\u2019s Toccata and Fugue in D Minor (BWV 565) as a computational acoustic system, representing the work\u2019s multi-voice organ texture across its major structural sections, including the Adagio opening, Prestissimo toccata passages, Fugue, Recitativo, Adagissimo, Presto, and closing Adagio\/Vivace material. The package generates synthetic waveforms using additive harmonic synthesis inspired by organ pipe acoustics and produces structured note-level data together with derived features such as RMS power, spectral centroid, polyphony count, tempo, and section annotations. Multiple scenarios capture contrasting interpretations and registrations, including fast, slow, bright, dark, and fugue-only settings. The resulting bundle is intended for research and teaching in music information retrieval, acoustics, and signal processing, enabling analysis of tonal structure, timbral variation, and large-scale musical form in a canonical Baroque organ work."

本数据集与仿真模型将约翰·塞巴斯蒂安·巴赫的D小调托卡塔与赋格（Toccata and Fugue in D Minor，BWV 565）构建为计算声学系统，完整还原了该作品各主要结构段落中的多声部管风琴织体，涵盖开篇柔板（Adagio）段落、极快板托卡塔段落、赋格（Fugue）、宣叙调（Recitativo）、极慢板（Adagissimo）、急板（Presto）以及结尾的柔板/活泼乐段素材。
该工具包采用受管风琴声学启发的加性谐波合成（additive harmonic synthesis）技术生成合成波形，同时输出结构化音符级数据与各类衍生特征，包括均方根功率（RMS power）、频谱质心（spectral centroid）、复音数（polyphony count）、演奏速度以及段落标注。
多种预设场景可模拟差异化的演奏演绎与管风琴音栓配置（registrations），涵盖快速演奏、慢速演奏、明亮音色、暗沉音色以及仅保留赋格段落等参数设置。
本数据集包旨在为音乐信息检索（music information retrieval）、声学与信号处理领域的研究与教学提供支持，助力研究者与学习者分析这部经典巴洛克管风琴作品的调性结构、音色变化与大型曲式特征。
