Zeta iolin vibrato technique and its implication for pitch perception

A major concern when performing on the Zeta violin is the perceptible time delay of triggering sound samples when using specific bowed articulations. Results in this study show that there is a much longer time delay when there are low-pitched sounds (30-70 ms) compared to higher-pitched ones (15-45 ms). Articulations that have strong attack transients (e.g. pizzicato and martele) have a much shorter time delay than other articulations such as detache. Many non-conventional techniques are developed to minimize delay and pitch detection errors.

One of the promising applications of the Zeta violin is its use in developing technical skills on the violin. Position shifting exercises are monitored both visually and aurally using MAX. Other interactive exercises include maintaining evenness of bow strokes and fingering and controlling vibrato width and speed.
