ABSTRACT

Digital versions of musical instruments have been created for several decades, and for good reasons! They are more compact, more easy to maintain, and generally less difficult to play than their real-life counterparts.

One way to digitise an instrument is to record it and play back the samples, but this does not capture the entire range of expression of the real instrument. Simulating an instrument based on its physics, including its geometry and material properties, is much more flexible to player control.

An application of physical modelling, is to simulate instruments that are unplayable as they are too rare or vulnerable. A model of the underlying physics of the instrument could potentially resurrect the instrument making it available to the public again.

Furthermore, as a simulation is not restricted by the laws of physics, it could possibly go beyond what is physically possible. Properties such as the material or geometry of an instrument could be dynamically changed, which could potentially broaden the range of expression of the musician.

This PhD project has focused on the real-time implementation of several traditional instruments using finite-difference time-domain (FDTD) methods. The instruments include the well-known trombone, as well as more obscure instruments, such as the tromba marina and the hurdy gurdy.  Finally, a novel method has been created that paves the way for physically impossible manipulations of the instruments.

The PhD Dissertation as a download, can be obtained from Silvin Willemsen by sending an email to him.
