A framework is proposed for generating interesting, and musically similar variations of a givenmonophonic melody. The focus is on rock/pop guitar and bass-guitar melodies with the aim of eventual extensions to other instruments and musical styles. It is demonstrated here how learning musical style from segmented audio data can be formulated as an unsupervised learning problem to generate a symb...

In this paper we describe an ongoing research on augmented instruments, based on the specific case study of the electric guitar. The key question of the relationship between gesture, instrument and sound is approached via an analysis of the electric guitar’s design, playing technique and interface characteristics. The study points out some inherent defaults in the guitar’s current forms of acou...

The paper analyzes different right-hand guitar techniques, such as the use of block chords, the balance between independent musical voices and layers, and global rhythmic control. Three well-known musical excerpts were chosen from the twentieth-century repertoire for guitar and were played in three different renditions: the beginning of Rodrigo’s Entre Olivares, Brouwer’s Étude II and a phrase ...

Sensor-based gesture recognition is investigated as a possible solution to the problem of managing an overwhelming number of audio effects in live guitar performances. A realtime gesture recognition system, which automatically toggles digital audio effects according to gestural information captured by an accelerometer attached to the body of a guitar, is presented. To supplement the several pre...

Computational expressive music performance studies the analysis and characterisation of the deviations that a musician introduces when performing a musical piece. It has been studied in a classical context where timing and dynamic deviations are modeled using machine learning techniques. In jazz music, work has been done previously on the study of ornament prediction in guitar performance, as w...

In this paper, timbre of stringed instrument is analyzed and the timbre sound is synthesized. Timbre is familiar and looks well known, but it has been unknown even now what an essential factor is. And it is the most important factor for human to distinguish sounds with the same duration, loudness and pitch. The formant structure model for keeping the same timbre is proposed in this paper. The s...

While vacuum tubes have been almost completely replaced by solid state electronic devices, there are still a few applications where vacuum tubes are used. One of these is in guitar amplifiers. As there are few companies still producing new vacuum tubes, most of the tubes used in amplifiers are old. The electric guitar was invented in the early twentieth century after the advent of the vacuum tu...
