Listening to the piece that I wanted to do my paper on I realized something about reverb. It is cool as hell. I never really noticed it before, but when I was really trying to listen to everything in the piece in order to grasp its entirety, I came across reverb. Actually, it the was the first thing that caught my ear. I just find it so cool. It gives everything this ringing sound that I relate to like 'the sound of royalty.' Everything rings in your ear even after the notes are finished. It is truly amazing. It's like the music surrounds your whole entire head and slowly dissipates into the air.
If you were to play a piece on an acoustic instrument, then brought it onto the computer, would you be able to take away the fundemental notes and only leave the harmonics. I wonder how it would sound. I assume the relationship from each note would be the same, only those notes wouldn't be there, only the harmonics. I wonder if anyone has created a piece like this, that is if it's possible of course.

A sound with its fundamental (if we consider pitch) taken away is not that difficult to implement. In some ways, the low-pass filters (as well as the band pass, and peak-notch) were doing to this to the sound examples. ALthough we have to realize that if a sound has its "fundamental" taken away, there is still much, much more contained within the sound besides an audible harmonic series. It depends on the sound. THeoretically, you are correct---you would only be left with the 'harmonics' of the sound--because essentially the timbre of a sound is its unique collection (and summation) of specific amplitudes of the harmnonic series. Within many acoustics sounds, however, there exists a fair amount of noise--that is, some imperfections, which give an acoustic sound that instable, more organic character we notice.
The voice is a good example of this. I would invite you to try this with your own voice---using MSP--and see what you come up with. Try to get different variations of harmonics.
Specifically, you can look at various filters, comb filters, and many techniques within the category: spectral processing. We can also look at use of the vocoder to change your voice.
