The Birl is an electronic wind instrument developed by the authors, which uses artificial neural nets for the mapping of fingering systems and embouchure position. The design features of the instrument are described, and the selected machine-learning mapping strategy is discussed.

This work presents a method for the extraction of instrumental controls during guitar performances. The method is based on the analysis of multimodal data consisting of a combination of motion capture, audio analysis and musical score. High speed video cameras based on marker identification are used to track the position of finger bones and articulations and audio is recorded with a transducer ...

5 Direct numerical simulations (DNS) of a shear layer with salt-fingering-favorable stratifica6 tion have been performed for different Richardson numbers Ri and density ratios Rρ. When 7 the Richardson number is infinite (unsheared case), the primary instability is square plan8 form salt-fingering, alternating cells of rising and sinking fluid. In the presence of shear, 9 salt-fingering takes t...

It is common sense that playing music in the exact way it is written in the score results in a mechanical and uninteresting succession of sounds. In fact, the score is just a guide to the musician, who changes it according to his musical intentions, to some sort of empirical analysis of the musical structure and performance rules he learned during his musical life. These modifications are calle...

Immiscible fluid–fluid displacement in porous media is of great importance many engineering applications, such as enhanced oil recovery, agricultural irrigation, and geologic CO2 storage. Fingering phenomena, induced by the interface instability, are commonly encountered during processes somehow detrimental since hydrodynamic instabilities can significantly reduce efficiency. In this study, we ...
