The“Database of Traditional Singings in China”is a research-oriented knowledge base centered on Chinese folk singing performances and vocal techniques.The database adopts a“dual-databases interconnection”architecture,comprising two sub-databases:the“Repertoire Database"and the“Special Vocal Techniques and Idioms Database.”The former systematically collects and analyzes folk singing repertoires from various ethnic groups and regions,while the latter documents special vocal techniques along with their localized knowledge systems.In addition to meeting basic data storage and efficient retrieval needs,the database features dynamic display of multimedia materials,visualization of the geographical distribution of singing,audio tagging for vocal technique types,and a tiered access management system.This article systematically elaborates on the construction process,design features,and theoretical significance of the database from the aspects of theoretical positioning,metadata framework,data platform functions,and implementation pathways.It analyzes 52 vibrato singing samples from 19 ethnic minorities to demonstrate the potential application of database in cross-cultural music comparative research.
