MAST rhythm dataset

The MASTrhythm dataset is a collection of 3721 audio files cropped from recordings of conservatory entrance examinations in Turkey (summer 2015 and summer 2016). (see the previous version with audio data here: https://zenodo.org/record/2620357#.Y1ZOVXVBwW0 ) This version of the dataset includes new annotation files. <strong>4 level grades re-collected by blind-random-listening</strong>: A new set of grades were collected using an annotation tool that randomly plays audio recordings and ask the annotator to pick a grade from the set of grades: 1-Completely Off, 2-Major Mistakes, 3-Minor Mistakes, and 4-Perfect. The assessments were done by three individuals who specialized in music or have a musical background; the first annotator is a professor of musicology who has taken part as a jury member in many entrance exam auditions, the second and third annotator are music conservatory students of graduate-level programs. A rubric was explicitly defined and used for grading: If only one or two notes were wrong (missing, added, or played in a different rhythmic position), while the rhythmic accents were executed perfectly and without any delay or hurry, this type of error is considered as a "3-minor mistake"; If two-three notes were wrong, and were belonging to any form of hesitation with poorly executed accents, such performances were graded as a "2-major mistake". Any performance with more than three wrong strokes/durations was considered "1-completely off". The 4-level grades are shared in the format of text files: annotator#.txt <strong>Naming convention:</strong> The dataset is composed of audio files. All other information is coded in the file names: 'ref': reference recording, 'per': performance recording, 'fail': performance graded as 'fail', 'pass': performance graded as 'pass' There exists 40 distinct rhythmic patterns. The ID for the melody makes up the first part of the file name. Examples: '51_rhy1_per101559_fail.m4a': Rhythmic pattern ID: '51_rhy1', this is a candidate performance recording (candidate ID: 101559) graded as fail '55_rhy2_ref280758.m4a': Rhythmic pattern ID: '55_rhy2', this is a reference recording (performed by a jury member) for candidate with ID: 280758. <strong>Acknowledgement:</strong> This new version of the dataset has been curated within the TUBITAK (The Scientific and Technological Research Council of Turkey) funded research project 1001-121E198 targeting development of automatic assessment tools for music performances.MASTrhythm数据集是从土耳其2015年夏季与2016年夏季音乐学院入学考试的录音素材中截取得到的3721个音频文件集合（含原始音频数据的旧版数据集可访问：https://zenodo.org/record/2620357#.Y1ZOVXVBwW0）。本版本数据集新增了标注文件。 **基于盲听随机播放的4级评分集**：本次新增的评分集通过一款标注工具完成采集，该工具会随机播放音频文件，并要求标注人员从以下4个等级中选定对应评分：1-完全不合格（Completely Off）、2-重大失误（Major Mistakes）、3-轻微失误（Minor Mistakes）、4-完美（Perfect）。本次评分由3位具备音乐专业背景或相关专长的人员完成：第一位为音乐学教授，曾多次担任音乐学院入学考试试听环节的评委；第二、第三位为音乐学院研究生项目在读学生。 本次评分统一采用明确制定的评分准则：若仅出现1至2个音符错误（漏奏、加奏或节奏位置演奏偏差），且节奏重音演奏完美无拖沓或仓促，则此类错误被判定为“3-轻微失误”；若出现2至3个音符错误，且伴随演奏迟疑、节奏重音处理不佳，则该演奏被评为“2-重大失误”；若错误的演奏时长或击奏超过3处，则被判定为“1-完全不合格”。 4级评分结果以文本文件形式存储，命名格式为`annotator#.txt`。 **命名规范**：数据集核心为音频文件，其余所有信息均编码于文件名中： - `ref`：参考示范录音（由评委演奏的标准录音） - `per`：考生演奏录音 - `fail`：被评为“不合格”的演奏 - `pass`：被评为“合格”的演奏 本数据集包含40种不同的节奏型。旋律ID为文件名的首段内容，示例如下： 1. `51_rhy1_per101559_fail.m4a`：节奏型ID为`51_rhy1`，为考生ID 101559的演奏录音，评分结果为不合格； 2. `55_rhy2_ref280758.m4a`：节奏型ID为`55_rhy2`，为考生ID 280758对应的参考示范录音（由评委演奏）。 **致谢**：本数据集的新版本由土耳其科学和技术研究理事会（TUBITAK）资助的1001-121E198号研究项目打造，该项目旨在开发音乐演奏自动评分工具。
