music frequency


The only thing I know about the frequency is that the audible to human ear is 20-20khz and the middle C on the piano is 250hz. Can you tell me what frequency range a complex orchestra music might be?

Not sure you're right about middle C. Someone else will have to chime in on that one. But here are two charts that should answer your question about orchestras:

My spectrum analyser indicates that the high end of most recorded music rolls off around 12-14 KHz most of the time. Sometimes (not often) there is significant signal up to 20 KHz. The low end varies greatly. Usually nothing below about 40 Hz, but again there are times when the 20 Hz third octave is as high as any other.
I know most acoustic instruments are between 50 hz and 3800 hz according to a chart in an old TAS magazine.
What you guys are missing here are the overtone series that these insturments and voices produce. These are the sonic signatures that make the 440 from a piano sound different from that of a violin or other insturment. These freqencies can extend well beyond the human spectrum of hearing and are vital in listening to music.

Close! Middle C is 261.63Hz. Nice links Pabelson, but where is the triangle? Oh the horror ... the horror! Liszt they have forsaken thee..... ;-)
