古筝演奏技法数据集 Guzheng IsoTech Dataset

本数据集包含2824个古筝单技法音频片段(.wav格式)。其中2328个片段是从虚拟音源中收集得到，496个片段是由专业古筝演奏家弹奏并录制的。这些片段几乎涵盖了古筝音域范围内的音调以及最常用的技法。根据古筝不同的演奏技法，将它们分为8类：颤音、上滑音、下滑音、回滑音、刮奏（刮奏、花指）、摇指、泛音、拨弦（勾、打、抹、托……）。每种演奏技法都有若干个对应的音频。

This dataset comprises 2824 single-technique audio clips of the guzheng, all stored in .wav format. Of these, 2328 clips are collected from virtual sound libraries, while the remaining 496 clips are recorded by professional guzheng performers. These clips cover nearly all pitches within the full tonal range of the guzheng and the most commonly utilized playing techniques. Based on the distinct playing techniques of the guzheng, the clips are categorized into 8 groups: vibrato, upward portamento, downward portamento, return portamento, glissando (including scraping and flower finger), tremolo, harmonics, and plucking techniques (including hook, strike, inward stroke, outward stroke, and others). Each playing technique category contains multiple corresponding audio clips.
