Pitch and volume can be measured with sound meters, and in modern saxophones, the tone holes are machine made, which means that 100 % pitch accuracy can be achieved. But timbre can never be completely mastered through quantitative means.
其中音準、音量可以用音度計測試，加上現代薩克斯風的音孔是以機械開孔，音準可以百分之百精準，唯獨音色卻始終無法用量化方式完全掌握。
