The first task was analyzing the materials used for making saxophones. The MIRL bought an international-brand saxophone costing more than NT $ 200,000, and found that the brass used to make it had a copper content of 65 %, which makes it more difficult to work with than the 70 % copper content in the brass used for Taiwanese instruments, but produces a more resonant sound.
首先對材料進行分析，為此機械所特地以二十多萬元買進一把國際最知名品牌的薩克斯風，發現國際品牌的銅板，銅與其他成份的比例是 65：35，在製作難度上比國內 70：30 比例的銅板高，但是共鳴感較佳。
