IDMT-SMT-Bass-Single-Track Dataset

The IDMT-SMT-BASS-SINGLE-TRACK dataset comprises of 17 bass lines from different music styles. It is intended as a public evaluation dataset for: retrieval of repetitive bass patterns For each bass line, the pattern length (in seconds) and the begin of the first pattern appearance (in seconds) is annotated. The patterns are in general no exact repetitions but instead contain occasional pitch and rhythm variations. bass transcription Each note is annotated with the score-related parameters onset, offset and pitch. spatial transcription / estimation of the fretboard position Each note is annotated with the instrument-related parameters string number and fret number. estimation of bass guitar plucking styles Each note is played and annotated with one of the 5 plucking style classes: Finger-style (FS) - alternate plucking of the string using the index and middle finger Picked (PK) - plucking of the string using a plastic pick Muted (MU) - plucking of the string using the thumb and index finger while simultaneously damping the string vibration using the palm of the hand Slap-Pluck (SP) - picking of a string using either the index or the middle finger (causing a collision between the string and the upper frets) Slap-Thumb (ST)- striking of the string using the thumb (causing a collision between the string and the upper frets) estimation of bass guitar expression styles (6 classes) Each note is played and annotated with one of the 6 expression style classes: Normal (NO) - no expression, just “regular” bass note playing Harmonics (HA) - flageolet tones Dead-note (DN) - damped, percussive note Bending (BE) - singular bending of the string during vibration Vibrato (VI) - periodic bending and releasing the string during vibration Slide (SL) - slide up or down after note is pluckedIDMT-SMT-BASS-SINGLE-TRACK数据集收录了17段来自不同音乐风格的贝斯线条。 该数据集旨在作为面向以下任务的公开评测数据集： 重复贝斯线条模式检索 针对每段贝斯线条，已标注其模式时长（单位：秒）与首个模式出现的起始时刻（单位：秒）。 这些模式通常并非完全重复，而是偶尔会出现音高与节奏的变化。 贝斯线条记谱转录 每个音符均已标注乐谱相关参数：起始时刻、结束时刻与音高。 指板位置空间转录与估测 每个音符均已标注乐器相关参数：琴弦编号与品丝编号。 电贝斯拨弦风格估测 每个音符的演奏方式均已标注为以下5种拨弦风格类别之一： - 指弹拨奏（Finger-style, FS）：使用食指与中指交替拨弦 - 拨片拨奏（Picked, PK）：使用塑料拨片拨弦 - 制音拨奏（Muted, MU）：使用拇指与食指拨弦，同时用手掌制停琴弦振动 - 拍击拨奏（Slap-Pluck, SP）：使用食指或中指拨弦，使琴弦与上方品丝产生碰撞 - 拇指拍击奏（Slap-Thumb, ST）：使用拇指敲击琴弦，使琴弦与上方品丝产生碰撞 电贝斯演奏表情风格估测（共6类） 每个音符的演奏表情均已标注为以下6种表情风格类别之一： - 普通演奏（Normal, NO）：无特殊表情，仅为常规贝斯音符演奏 - 泛音演奏（Harmonics, HA）：自然泛音演奏 - 闷击音（Dead-note, DN）：带制音的打击感音符 - 推弦演奏（Bending, BE）：琴弦振动过程中单次推弦 - 颤音演奏（Vibrato, VI）：琴弦振动过程中周期性推弦与释弦 - 滑音演奏（Slide, SL）：音符拨奏后向上或向下滑音
