AGPTset: Acoustic Guitar Playing Technique dataset

THIS REPOSITORY IS ANONYMOUS FOR DOUBLE BLIND REVIEW OF THE RELATED PUBLICATION This is the Acoustic Guitar Playing Technique dataset. It contains 15 hours and 55 minutes of monophonic recordings of 12 expressive guitar playing techniques (pitched and percussive). Of these, 10 hours and 4 minutes of recordings encompassing 8 of the 12 techniques have been labeled, meaning that onsets were identified at the millisecond level and their timestamp was saved, alongside playing technique information. As a result, 32,592 individual notes have been labeled. Recordings were performed by 6 players on 7 different acoustic steel-string guitars. The techniques are the following: ``Kick'' technique (*percussive*): producing a sound that resembles a kick drum by hitting the lower right part of the top of the guitar body; ``Snare-A'' technique (*percussive*): producing a sound by hitting the lower right side of the guitar body; ``Tom'' technique (*percussive*): producing a sound by hitting the area of the guitar body near the top of the end of the fretboard, using the thumb; ``Snare-B'' technique (*percussive*): producing a sound by hitting the muted strings over the end of the fretboard; Natural Harmonics (pitched): plucking the strings while lightly touching the string with the fretting finger (i.e., not pressing the string fully), therefore letting only some harmonic overtones ring; Palm Mute: partially muting the strings with the palm of the picking hand, resulting in a muffled sound. ``Pick Near Bridge'' (pitched): plucking the string near the guitar bridge, producing sounds with great high-frequency content; ``Pick Over the Soundhole'' (pitched): plucking the string over the soundhole, producing sounds with lower treble content and greater intensity; Bending technique (pitched): pulling the strings, raising the pitch (half-tone interval); Hammer-on technique (pitched): sharply bringing a finger down onto the fingerboard, creating a legato sound (half-tone interval); Staccato (pitched): playing short notes; Vibrato (pitched): Moving the fretting finger to warp the pitch and tone of the sound. Techniques 1 through 8 have been meticulously labeled. THIS REPOSITORY IS ANONYMOUS FOR DOUBLE BLIND REVIEW OF THE RELATED PUBLICATION

本数据集为原声吉他演奏技法数据集，包含总时长15小时55分钟的单声道录音，涵盖12种富有表现力的吉他演奏技法（分为音高类与打击类）。其中，时长10小时4分钟的录音已完成标注，覆盖12种技法中的8种，标注精度达到毫秒级，不仅保存了音符起始时间戳，还附带对应演奏技法信息，总计标注了32592个独立音符。
本次录音由6位演奏者使用7把不同的原声钢弦吉他完成。所涵盖的演奏技法如下：
1. 击板（Kick）技法（打击类）：通过敲击吉他琴身面板右下区域，发出类似底鼓的声响；
2. 军鼓A（Snare-A）技法（打击类）：通过敲击吉他琴身右下侧，发出类似军鼓的声响；
3. 嗵鼓（Tom）技法（打击类）：用拇指敲击吉他琴身靠近指板末端上端的区域，发出类似嗵鼓的声响；
4. 军鼓B（Snare-B）技法（打击类）：敲击指板末端上方的制音琴弦，产生相应声响；
5. 自然泛音（Natural Harmonics）技法（音高类）：在拨弦的同时用按弦手指轻触琴弦（而非完全按实），仅使部分泛音共鸣发声；
6. 手掌制音（Palm Mute）技法：用拨弦手的手掌部分制音琴弦，获得闷音效果；
7. 近琴桥拨弦（Pick Near Bridge）技法（音高类）：在靠近吉他琴桥的位置拨弦，得到高频成分丰富的音色；
8. 音孔上方拨弦（Pick Over the Soundhole）技法（音高类）：在吉他音孔上方拨弦，获得低音调成分较少、响度更高的音色；
9. 推弦（Bending）技法（音高类）：拉动琴弦以升高音高（半音程）；
10. 锤弦（Hammer-on）技法（音高类）：用手指快速击按指板，产生连奏音效（半音程）；
11. 断奏（Staccato）技法（音高类）：演奏短促的单个音符；
12. 揉弦（Vibrato）技法（音高类）：移动按弦手指以改变音高与音色，产生颤音效果。
技法1至8均已完成精细化标注。
