What is the max frequency the music is recorded at?  What sound be at the high frequency ranges?

By the Nyquist theorem it's half of the sampling rate.

Typical sampling rates are 44.1 kHz, 48 kHz, 96 kHz, etc.

 

There is very little sound above 20 kHz, mostly higher harmonics of things like cymbals. Nobody can hear above 22 kHz anyway.

Points to consider:

a] While musical instruments can make noises up to 100kHz, I would hesitate to call them musical.!

b] Those high frequency measurements were made very close to the musical instrument using special cal mics.

c] At a typical listener position, those extremely high frequencies are nonexistent.

d] The mics that good engineers choose often have rolled off high frequency response.

e] Even audible high frequencies are masked be louder lower frequency sounds.

f] With real would reasonable music, 14kHz is about all you need.

The eight octaves in the middle of human hearing are the most important. That's where music resides.

Well, if you are a  REAL audiophile, enough is never enough.  You need at least 6 megahertz of bandwidth to get close to real.  Why 6 mhz?  Because anything less is less.  6 mhz is lower end video.  You can see what you hear.  So a sample rate of 12,000 khz is the minimum to get close.  Presently available digital audio rates are perhaps (and I use the term advisedly)  perhaps equal to pretty good cassette.  We need not mention LP with its infinite sample rate. 

 

 

Hahahahahahahahahaha!

It depends on the microphones used.

Even a high quality condenser mic like this Neumann will drop off around 20kHz.
