Abstract The early Violin Concerto (1907–1908) dedicated to the young violinist, Stefi Geyer, is regarded as one of most personal compositions by Béla Bartók. transparent structure, and ethereal, unearthly tone first movement, probably inspired Geyer’s playing, belongs warmest intimate used composer. Presumably, its re-emergence in certain passages two Violin-Piano Sonatas (1921 1922) was not c...

We describe the design of a Kalman filter that identifies suspension violin modes in an interferometric gravitational wave detectors data channel. We demonstrate the filter’s effectiveness by applying it to data taken on the LIGO 40M prototype.

In this paper we present a method to model and compare expressivity for different Moods in violin performances. Models are based on analysis of audio and bowing control gestures of real performances and they predict expressive scores from non expressive ones. Audio and control data is captured by means of a violin pickup and a 3D motion tracking system and aligned with the performed score. We m...

The console gaming industry is experiencing a revolution in terms of user control, due in large part to Nintendo’s introduction of the Wii remote. The online open source development community has embraced the Wii remote, integrating the inexpensive technology into numerous applications. Some of the more interesting applications demonstrate how the remote hardware can be leveraged for nonstandar...

We present here the development of optical pickup for acoustic violin. Unlike other optical pickups, this one works in a reflective mode which is potentially less intrusive. This pickup, aimed principally at pitch tracking, uses a modulation technique to improve the signal-to-noise ratio, and limit artifacts of the ambient light.

This paper is an attempt to solve two problems related to musical acoustics. The first one consists in defining a signature of an instrument, namely, summarizing its vibroacoustical behavior. The second one deals with the existing relationship between the musical sound and the vibroacoustic properties of the instrument body. The violin is the application of this paper. A proposed solution for t...

Several new technologies to capture motion, gesture and forces for musical instrument players’ analyses have been developed in the last years. In research and for augmented instruments one parameter is underrepresented so far. It is finger position and pressure measurement, applied by the musician while playing the musical instrument. In this paper we show a flexible linear-potentiometer and fo...

Controlling the stick-slip friction phenomenon is of major importance for many familiar situations. This effect originates from the periodic rupture of junctions created between two rubbing surfaces due to the increasing shear stress at the interface. It is ultimately responsible for the behavior of many braking systems, earthquakes, and unpleasant squeaky sounds caused by the scratching of two...
