In this demo, the Chinese Musical Notation Annotation Tool is introduced with its most important features. This tool plays an important role in the creation of the first publicly available symbolic dataset of ancient Chinese music notations KuiSCIMA. The annotation of three different kinds of music notations for the creation of optical-symbolic annotations is shown: guqin notation jianzipu 减字谱, court ritual musical notation lülüpu 律吕谱, and the common musical notation of Song dynasty suzipu 俗字谱. In addition, the export of the dataset files to MusicXML, numbered musical notation jianpu 简谱, and staff notation is shown. The plugin system allows users to annotate custom music notations, which may include gongchepu 工尺谱 notation as used in Cantonese jyutkek粤剧 or kunqu 昆曲 musical theatre.
