This paper presents some applications of time-frequency representations to the study of guitar sounds. These techniques allow to estimate acoustically relevant parameters such as frequency and time behaviours of the components. From real guitar sounds recorded in an anechoïc room, we have made a link between the structure modifications of the instrument and sound parameters such as Helmholtz, top-plate and the first harmonic components of the sound. In addition, these techniques allow to re-synthesize independantly each component, giving a new audio-tool to the instrument designer.
