Comparison of Real Trumpet Playing, Latex Model of Lips and Computer Model
Christophe Vergez, Xavier Rodet · 1997
For several years, we have been developing and studying computer-simulated models of brass instruments including the player's lips. We demonstrate here such a physical model. It is played in real-time with MIDI events. We present recent developments concerning both physical functioning and real-time controls. They result in great improvements of sound quality and musical expressivity. To better understand the physics of real lips, we have built a latex model of the lips. We show that this artificial mouth can play a trumpet like a real trumpet player. We analyse lips behavior and acoustic measurements. We make comparisons between naturally blown trumpet signals, artificially blown trumpet signals, and simulations with our computer model. 1 Introduction In [8], we explained and demonstrated a simple realtime model of trumpet-like instruments. The aim was to find the simplest structure which would exhibit the basic properties of this class of instruments. Furthermore, as long as we keep...
