Acousticians have long debated whether and how the resonances of the vocal tract are involved in the playing of clarinet and saxophone. We measured the resonances of saxophonists' vocal tracts directly while they played. Over most of the instrument's range, there is no simple relation between tract resonances and the note played, and the tract resonances varied among players. In the high (altis...

In this paper we introduce the use of bond graphs for the implementation of classic physical models of musical instruments. Bond graphs are a diagrambased technique for representing physical systems, such as an electrical circuit or a mechanical engine. They provide a precise and unambiguous modelling tool which allows for the specification of hierarchical physical structures. The paper begins ...

This paper proposes a methodology to map the various acoustic regimes of wind instruments. The maps can be generated in a multi-dimensional space consisting of design, control parameters, and initial conditions. The boundaries of the maps are obtained explicitly in terms of the parameters using a support vector machine (SVM) classifier as well as a dedicated adaptive sampling scheme. The approa...

Most digital waveguide models of woodwind instruments to date have provided only basic control parameters such as frequency, breath pressure, and vibrato. It is clear that if these models are to gain popularity as real-time performance synthesizers or as composition tools, more flexibility is necessary. This paper discusses the implementation of expressive controls for flutter tonguing, growlin...

We propose here to combine sideband holography with stroboscopic illumination synchronized with the vibration of an object. By sweeping the optical frequency of the reference beam such a way the holographic detection is tuned on the successive sideband harmonic ranks, we are able to image the instantaneous velocities of the object. Since the stroboscopic illumination is made with an electronic ...

In the measurement of the amplitude of vibration of objects, holographic imaging techniques usually involve fringe counting; because of the limited resolution of the images, measurements of large amplitudes are not accessible. We demonstrate a technique that suppresses the necessity of fringe counting--frequency sideband imaging--where the order of the sideband is considered a marker of the amp...

This paper introduces Die Lebensfreude, a pioneering piece of music composed with the aid of an amoeba-like plasmodial slime mould called Physarum polycephalum. The composition is for an ensemble of five instruments (flute, clarinet, violin, cello and piano) and six channels of electronically synthesises sounds. The instrumental part and the synthesised sounds are musifications and sonification...
