[microsound] Piano Paradox

[Kim Cascone]

a couple of thoughts about this experiment:

first of all, you need stationary end points thereby creating a string 
of finite length in order to produce a vibratory phenomenon of pitch

but let's say you somehow worked this out
then you would need infinite energy to set an infinite string into motion
which seems to me physically (and mathematically) problematic

and if the statement 'all parallel lines meet at infinity' (in 
non-Euclidean geometries) is true
then all the strings would be joined at some infinite point which could 
behave as a bridge

each string would have to have a starting point -- but IIRC I don't 
think this exists on an infinite line which I believe extends to 
infinity in both directions (?)

and if the infinite points at both ends of the string are the same point 
of infinity then I would guess the string is actually a circle?

I've read some Cantor but by no means a mathematician

anyone with a real math background shed some light on this?
