This paper discusses acoustical properties and proposes a sound synthesis model for the plucked stringed instrument called guqin. The guqin is an ancient Chinese musical instrument with seven strings. The strings are plucked with the right hand while the left hand pushes the strings against the top plate of the body. In the playing of the instrument, slides and flageolet tones are an important part of the expression of the instrument. The instrument disappeared almost completely during the cultural revolution, but it has began a revival and now there are already thousands of players. A database of tones was recorded in anechoic conditions. The acoustic signal analysis and the model is based on these signals. The sound synthesis model is based on the digital waveguide technique. The physical model takes into account the most vital parts of the characteristics of the instrument. 1.
