It's an interesting idea for sure. A similar attempt has been made to make a piano "speak".Unfortunately the video is in German, but is subtitled and the "spoken" words are in English, so you'll get the idea.http://www.youtube.com/watch?v=muCPjK4nGY4
(1) x number of precisely tuned bells, such that, given the available frequencies, most frequencies within the human hearing range can be more or less recreated by some combination (i know there is an embedded math problem,
It's nearly impossible (maybe entirely impossible) to make a mechanical device that vibrates at a single-pure-tone without ringing. You can do it with electronics, but, building such a device is, of course, not practical.
DFT = digital Fourier Transform
I suspect the piano speaking video is fake. [Although I don't speak German, so perhaps they explain more than I am aware of] It is a trick. We are NOT hearing just an unmodified piano. We are hearing either a gimmicked piano or a secondary "enhancement" soundtrack has been mixed in. The give away is the clarity of some of the the voiceless fricatives (such as the "/s/" in "responsible")[Examples of voiceless fricatives may be heard in the demonstration videos of a face to the far right, here. Click "Fricative" and then try the five shown: http://www.uiowa.edu/~acadtech/phonetics/e...mp;scrollbar=no should you need a better understanding of what they are]which a piano would have a hard time emulating. Here's another video and notice how much harder the words are to make out [in fact nearly impossible if you close your eyes and stop reading the text accompanying the sound.] Try it and see how few words you make out!http://www.youtube.com/watch?v=bFsRe6YSWwsI suspect on this second version I found, they have scaled back the "enhancement track".
Whenever a classical composer makes a score for 100 musicians. Isn't that sort of the same thing? Synthesizing some complex waveform using a large(ish) set of other complex waveforms. Now, composers might not think of the instruments as vectors in a large space

Now, composers might not think of the instruments as vectors in a large spaceThose 100 are certainly not playing e.g. voice. Probably not only because the vector space is too small, but also because it may fail to be closed under vector operations
One might claim that church organs are crude "non-sinoid" additive synthesis instruments.
