EPSRC : Adan Benito : EP/S022694/1The invention of the electric guitar at the beginning of the 20th century sparked a musical and cultural revolution that changed, not only how music was made and listened to, but also how new instruments were designed. However, new trends in popular music and in both electronic and digital advances, could be causing what many media outlets have called the demise of the guitar as a driver for cultural change.Although the electric guitar has widely been valued as a vehicle for musical expression, many of the efforts that have been carried out to bring the instrument up to date with the era of digital music fail to capture that richness. Attempts at creating interfaces based on the guitar using either sensors or analysis of the sound produced by the instrument have been carried out in the past but, given the complexity of the analysis of musical gestures and the translation of expressive meaning, these methods have never been widely adopted.With this research we propose to validate an augmented instrument prototype based on a guitar with sensors and an hexaphonic pickup to detect different kinds of string bending, a technique commonly used by guitarist to raise the pitch of the string to add articulation to their playing. This gesture has been popularly said to provide singing and talking qualities to guitar playing.We will extract information from both the audio signals produced by the instrument and sensors that detect string movement to obtain enhanced information enhanced information on how guitarists use this resource. We will then analyse how performers interact with the instrument during performance to assess the importance of this technique and to generate data that would later be used to better understand the characteristics of string bending as an expressive tool.

EPSRC：阿丹·贝尼托：EP/S 022694/1世纪初电吉他的发明引发了一场音乐和文化革命，不仅改变了音乐的制作和聆听方式，还改变了新乐器的设计方式。然而，流行音乐的新趋势以及电子和数字技术的进步，可能会导致许多媒体所称的吉他作为文化变革驱动力的消亡。尽管电吉他被广泛认为是音乐表达的载体，但许多努力使乐器与数字音乐时代同步，未能捕捉到这种丰富性。在过去，已经尝试使用传感器或乐器产生的声音的分析来创建基于吉他的界面，但是，考虑到音乐手势的分析和表达意义的翻译的复杂性，这些方法从来没有被广泛采用。通过这项研究，我们提出了验证一个增强乐器原型的基础上，吉他与传感器和六声道拾音器检测不同种类的弦弯曲，吉他手常用的技术，以提高字符串的音高，以增加他们的演奏清晰度。我们将从乐器产生的音频信号和检测琴弦运动的传感器中提取信息，以获得关于吉他手如何使用这一资源的增强信息。然后，我们将分析表演者在表演过程中如何与乐器互动，以评估这种技术的重要性，并生成数据，这些数据将用于更好地理解作为表达工具的弦乐弯曲的特征。
