This paper describes a plucked string synthesis model including a simplified tuning system and a right-hand playing style. The proposed model based on digital waveguide synthesis is applied to the Gayageum, a traditional Korean plucked string instrument. The Gayageum has 12 twisted silk strings, each supported by a movable bridge called an Anjok, which is placed on the body and is moved sideways along a string to tune it. The simplified tuning system is formulated with parameters related to the tension of the string and location of the Anjok, and these determine the pitch of a specific string. The unique right-hand playing style, a consecutive flick in which a player flicks a string twice in succession by the middle and index fingers, is implemented by a simple feed-forward filter. The proposed synthesis model is evaluated based on the frequency signal-to-noise ratio.
