Hi all,
I'm more or less a beginner in woodworking & making instruments, and am seeking to specialize in making the pear-shaped lyra/kemençe of Istanbul (http://lyrafiddle.com/)
As an experienced player, I'm also interested in discovering how to make my existing instruments sound better, and I'm thinking about investing a chunk of time in figuring out the bridge.
Since the instrument is not quite as standardized as the violin family, there seem to be many more variables to explore here, including:
- type of wood
- height of bridge
- curvature of top
- tapering from base to top
- thickness/length of arm (the bit that extends over the treble soundhole and sits directly on the soundpost)
- size of foot (the single piece that sits on the soundboard)
- number of holes & shape of holes
etc.
Does it makes sense to use any engineering design tools (i.e. modal analysis using FEM) to analyze the geometric variables, and is this even possible given the strong anisotropic properties of wood? Does anyone here have experience or words of advice in case I'm embarking on a futile mission?
