Hi, all
I am working a project of musical acoustics.
But I know nothing about music so I want to ask this stupid question.
WHAT IS P|TCH AND TIMBRE?
In my understanding, pitch is represented by a set of frequencies:
one fundamental frequency, and many others which are nearly integer
multiple of the fundamental frequency.
So different pitches have different fundamental frequencies.
But for different instruments, even the same pitch sounds different.
That i

音高是基本频率决定的
音色是由HARMONICAL FREQUENCY决定的,好比同样的A,在
吉他和钢琴上听着不一样,就是因为他们的HARMONICS不一样
但基本的A是一样的,叠加以后,波形图就不一样,听着就
不同.
EE的?呵呵,我也搞过一点儿AMP,设计过CLASS D

You guys are right, but let me add more.
Pitch should be the fundamental frequency itself.
And also, if you analyze the frequency response
of a note played by one certain instrument, the
fundamental frequnce occupy most of the energy.
And that is why the pitch is more obvious
than any other component of the note.(harmonies)
