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
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
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
I will also discuss some questions that had arisen during the modelling, and I
will shortly describe the implemented simulation.
