Description
The Langeleik is a stringed folk instrument consisting of one fretted melody string and a number of drone strings. In this paper we present the use of finite difference schemes (FDS) to implement a physical model of the Langeleik as a real-time, interactive web application using JavaScript and Web Audio. Hammer-on/pull-off interactions are modeled using non-iterative collision methods. The user interacts with the model by strumming with a mouse or touchpad, and pressing the frets with a computer keyboard. According to a qualitative evaluation of the application, the sound quality is satisfactory, but the design of the interaction can
be improved to provide a more intuitive experience.
