RaagBase
收藏资源简介:
RaagBase是一个专注于北印度古典音乐(Hindustani Music)的符号化文本数据集,由研究者基于Pt. Vishnu Narayan Bhatkhande的权威著作《Hindustani Sangeet Paddhati-Kramik Pustak Malika》创建。该数据集目前包含116条音乐作品样本,每条样本对应一个作品的音符频率分布,涵盖了Bhairav、Todi和Poorvi三种拉格(Raag),数据以CSV格式存储,源自乐谱的手动转录。其创建过程涉及从原始乐谱中提取音符序列,并将其映射为跨越三个八度(共36个可能音符)的频率分布,最终聚合为12个核心音符的频率特征。该数据集旨在支持计算音乐学研究,特别是通过图表示和图聚类技术解决拉格自动识别与分类问题,为音乐信息检索、教育推荐和智能归档等应用提供数据基础。
RaagBase is a symbolic textual dataset dedicated to Hindustani classical music, developed by researchers based on the authoritative monograph *Hindustani Sangeet Paddhati-Kramik Pustak Malika* by Pt. Vishnu Narayan Bhatkhande. As of now, the dataset comprises 116 musical work samples, with each sample corresponding to the note frequency distribution of a single work, covering three ragas: Bhairav, Todi, and Poorvi. The dataset is stored in CSV format and was derived from manual transcriptions of musical scores. Its construction process entails extracting note sequences from original musical scores, mapping these sequences into frequency distributions spanning three octaves (totaling 36 possible distinct notes), and ultimately aggregating these into frequency features of 12 core musical notes. This dataset is designed to support computational musicology research, specifically addressing the automatic recognition and classification of ragas through graph representation and graph clustering techniques, and serves as a data foundation for applications including music information retrieval, educational recommendation, and intelligent archiving.
