This paper describes a novel approach towards automatic evaluation of recorder performance. The processes from finding errors to the formulation of feedback are based on analyses of student performances and experience of recorder teachers. The developed algorithms were implemented in IMUTUS, a prototype practising environment for the recorder [3].
This paper presents some major results from the IMUTUS project 1. IMUTUS was an RTD project that aimed at the development of an open platform for training students on the recorder. The paper focuses on one of the most important and innovative parts of the IMUTUS system, the practicing environment. This environment integrates technological tools for the(More)
This thesis focuses on the analysis and modeling of scratching, in other words, the DJ (disk jockey) practice of using the turntable as a musical instrument. There has been experimental use of turntables as musical instruments since their invention, but the use is now mainly ascribed to the musical genre hip-hop and the playing style known as scratching.(More)
The art form of manipulating vinyl records done by DJs is called scratching, and has become very popular since it started in the seventies. Turntables are commonly used as expressive musical instruments in several musical genres. This phenomenon has had an serious impact on the instrument-making industry, as the sales of turntables and related equipment(More)
We performed an experiment to investigate differences between persons with and without hearing losses when playing a novel audio-based game on a tablet computer, and how persons with hearing losses appreciated the game when they played it with three different types of sound material---speech, music, or mixed speech and music. We analyzed game log files and(More)
This paper reports on two Short-Term Scientific Missions (STSM) in the ConGAS European Cost Action. Several sound models and (musical instrument) interfaces were combined to study how DJ gestures of scratching can be applied to new situations. In one experiment, the gestures were used to control a physics-based model of friction sounds, for instance to(More)
S-notation: A complete musical notation system for scratching and sample music derived from "Theory of Motions". ABSTRACT In this paper, we present and discuss the S-notation system for sample-based music, and particularly for DJ scratching and turntablism. Sonnenfeld developed the system from his Theory of Motion where scratch music is seen as(More)
