One of the questions that the classic philosophers asked was if color (chroia, what we now call timbre) of music was a physical quality that could be quantified (Campen 2007, Gage 1994, Ferwerda & Struycken 2001, Jewanski 1999).
经典的哲学家问及的问题之一是：音乐的颜色(chroia我们现在称之为音色)是否是一个可以量化的物理特性(2007,计1994年Campen Ferwerda & Struycken 2001,Jewanski 1999)。
