Abstract: The function of musical instruments has always been under study by physicists, engineers, and scientists in general, not only due to their apparent role in music production, but also because of the compelling physical effects that govern the process of sound generation. To this cause, music acoustics has developed as a science field that aims to study the underlying physics and to carry on asking further research questions, towards the understanding of the observed phenomena.

One issue that has seen increased interest in the past few years is the analysis of transient phenomena in wind instruments. The rapid variations that take place during tone transitions pose several problems to experimental and theoretical investigations alike. Therefore, even though the behavior of wind instruments during steady state sounds has been already well comprehended, the same can not be said concerning transient oscillations. The emergence of such transients during expressive performance in single-reed woodwind instruments will be the focus of the proposed research project.

The use of different articulation techniques available to the player, allows various ways to control the oscillations of the instrument and give expression to the sound. Recent research by the author has used experimental measurements to observe the differences in the resulting sound pressure. During the course of this project novel measurement techniques will be developed for the analysis of transients. Furthermore, a physical, time-domain model of a single-reed woodwind instrument will be formulated, suitable for the synthesis of transient phenomena. On the basis of both the experimental data and the physics-based analysis, an inverse model will be designed that can estimate physical parameter values from sounds recorded under real playing conditions. This way it is possible to extract information regarding, not only the musical instrument, but also how the player is controlling it in order to produce the desired sound.

With the use of inverse modeling it is possible to calculate the value of certain physically meaningful parameters that are impossible to track under real playing conditions. Furthermore, the model parameters can be associated to certain sound features and performance actions. It is thus possible to determine which of the underlying physical effects, that take place during transients, are significant for the generated sound. The development of an accurate and efficient physical model, which is able to capture transient phenomena, is thus invaluable for both sound synthesis and sound analysis applications.
