Based on the precise measurements of the reed vibrations (see Project: “Augmented Instruments”) on saxophone and clarinet, we started to investigate the effects of different articulation techniques towards the development of physical models capable of simulating and synthesizing realistic single-reed woodwind tone production [1,5].

These steps also involved a thorough calibration of the reed-sensors using Laser-Doppler Vibrometry and high-speed camera recordings [2], as well as an estimation of the sensor’s influence on the reed-vibrations using Laser interferometry [3]. Furthermore an empirical study was carried out to capture a variety of articulation techniques used by advanced clarinetists that showed the influence of the tonguing technique on the begin and end transients of clarinet sounds [4].
