Musical sound production is as old as mankind. During the past centuries

numerous suitable instruments were designed and produced by manufacturers. The

diverse shapes, features and technical realisation of these instruments were results of

empirical improvement.

Nowadays the love for music has remained unchanged, however demand has

been growing concerning the digital representation of the sounds of instruments.

Regardless of the currently dominant sample-based synthesis, the physical

model-based sound synthesis has been increasing in importance. For the mentioned

technique the sound is not a result of synthesis (adding or filtering) of pre-recorded

sound samples, but it is the output of the physical model of the musical instrument.

Therefore, besides sound production it could also play a role in perfectionating the

instrument.

In my thesis I will deal with the physical model-based synthesis of the piano. I

will describe the simplified physical model of the main mechanical elements (hammer,

string, soundboard), which play an important role in the sound production of this

instrument.

I will also discuss some questions that had arisen during the modelling, and I

will shortly describe the implemented simulation.
