This report is a follow-up (supplementary) study to the previously published "Simulation of Fingerboard Scoop and String Buz" and investigates the shape of the ideal scoop curve. Using the logarithmic spiral, conic sections (parabola, hyperbola, elliptical arc), power curves, and combined curves made by joining these with a sine curve, it examines which curve is the most ideal scoop curve.

This software is designed to help you easily create head designs for string instruments. Based on the dimensions you provide, it automatically generates a head design that you can freely modify into various shapes. Once your design is complete, you can simply print it out to make a physical head template.

This chart outlines how specific frequency bands shape an instrument's overall tone(timbre).

This software automatically generates Stradivari-style arching profiles based on the plate width and height (thickness) defined by the user. The generated profiles can be printed to create physical arching templates.

Many luthiers attempt to reconstruct the Stradivari arch, but with its constructive principles remaining unknown, they are limited to mere imitation. This report presents a method to systematically reconstruct the Stradivari arch using trochoid curves. Furthermore, this study presents a method to generate a Stradivari arch of any specified width and height for practical application in instrument making.
