The problem with Physical Models and their appeal to composers is not merely perceptual or aesthetic.Furthermore is not a question of understanding the physics and parameters of the actual instrument. Itis a question of achieving musical textures, realistic articulations and extending the qualities of a familyof sounds given by a single characteristic timbre in a Physical Model of an instrument. This can beachieved modeling and manipulating expression parameters for musical gesture. This paper describessome composition techniques for rendering a Computer Music piece using Physical Models as the primarysource technique for sound synthesis in non real time environments and parameter manipulation by meansof envelopes, randomness and chaotic signals for expressiveness.
