The sampling rate of a circuit is about 825 Hz.?
What would happen if you used this circuit to convert music to a digital format?
Would the digital format music be missing high or low frequency harmonics?

This (825 Hz) is actually pretty slow by today's common use. Some years ago people could choose the rate via terms of voice, something, and CD quality. The 825 would be the poorest of that; CD quality being about 11400 Hz (16 bit, stereo).
Anyway so you would get a rather imprecise copy, and would hear that especially when played through a high quality device. It might sound like it has a background of a whooshing heartbeat, or sound through a tin can.
The advantages are few, but it would for example save a little file storage space .

The audible frequency range is up to 20 KHz for young folks. Nyquist tell us that the very minimum sample rate is 2 time the frequency, so you need to sample at 40 KHz minimum.
