The focus of this work is in modeling the unique sound and the playing practices of the acoustic guitar. The results can be applied to other plucked string instruments too. A new extended notation package is used to produce expressive control information. This tool allows the user to add to the input score instrumental expressions and tempo functions. The system includes also a rule formalism that permits further fine tuning of the computer-generated performance. A real-time synthesis engine has been developed based on earlier results in digital waveguide modeling. We also describe an analysis of vibrato in acoustic guitar tones, which provides control information for realistic synthesis.
