Electric guitar playing is ubiquitous in practically all modern music genres. In the hands of an experienced player, electric guitars can sound as expressive and distinct as a human voice. Unlike other more quantised instruments where pitch is a discrete function, guitarists can incorporate micro-tonality and, as a result, vibrato and sting-bending are idiosyncratic hallmarks of a player. Simil...

In this paper, we present our research on left hand gesture acquisition and analysis in guitar performances. The main goal of our research is the study of expressiveness. Here, we focus on a detection model for the left hand fingering based on gesture information. We use a capacitive sensor to capture fingering positions and we look for a prototypical description of the most common fingering po...

This paper presents a detailed account on how a model-based state-of-the-art classical guitar synthesizer has been implemented in SuperCollider2 (SC2, McCartney 1998). SC2 is an attractive choice for model-based instruments as it is a general purpose and efficient software synthesizer containing a large set of predefined unit generators. It is also a high-level programming language allowing the...

This paper will focus on two important and under explored areas pertinent to interactive, improvisational performance. First, an overview of basic control strategies will be outlined. Next, techniques for acquiring control data from a real-time audio stream, and approaches to mapping this data to interactive digital signal processing functions, will be explored. Examples from a current work by ...

In this paper we describe a technique for creating guitar tablature using a neural network. Training data was parsed from an online repository of human-created tablatures. The contents of both the input layer and the set of training data have been optimized through genetic search in order to maximize the accuracy of the network. The output of the network is improved upon with a local heuristic ...

MIDI guitar synthesizers currently exist to transform the sound coming from the vibrating guitar strings to MIDI events. These achieve high accuracy and real-time performance through dedicated hardware. In particular, special pickups are used to generate a single signal for each string and special processing units convert the signals to MIDI events. This paper explores the ability to achieve re...
