In this paper, we present our research on the acquisition of gesture information for the study of the expressiveness in guitar performances. For that purpose, we design a sen- sor system which is able to gather the movements from left hand fingers. Our effort is focused on a design that is (1) non-intrusive to the performer and (2) able to detect from strong movements of the left hand to subtle movements of the fingers. The proposed system is based on capacitive sen- sors mounted on the fingerboard of the guitar. We present the setup of the sensor system and analyze its response to several finger movements.
