Abstract

GuiaRT is an interactive musical setup based on a nylon-string guitar equipped with hexaphonic piezoelectric pickups. It consists of a modular set of real-time tools for the symbolic transcription, variation, and triggering of selected segments during a performance, as well as some audio processing capabilities. Its development relied on an iterative approach, with distinct phases dedicated to feature extraction, transcriptions, and creative use. This article covers the motivations for this augmented instrument and several details of its implementation, including the hardware and strategies for identifying the most typical types of sound produced on a nylon-string guitar, as well as tools for symbolic musical transformations. This acoustic–digital interface was primarily designed for interactive exploration, and it has also been effectively used in performance analyses and as a pedagogical tool.

使用六音尼龙弦吉他进行实时符号转录和交互转换

摘要GuiaRT是一款基于尼龙弦吉他的交互式音乐装置，配有六音压电拾音器。它由一组模块化的实时工具组成，用于在演出期间对选定片段进行符号转录、变化和触发，以及一些音频处理功能。它的开发依赖于迭代方法，有不同的阶段专门用于特征提取、转录和创造性使用。本文介绍了这种增强乐器的动机及其实现的几个细节，包括识别尼龙弦吉他上产生的最典型声音类型的硬件和策略，以及符号音乐转换的工具。这种声学-数字界面主要是为互动探索而设计的，它也被有效地用于绩效分析和教学工具。
