Web Harp

A tightly stretched web is suspended from the inside corner of a vaulted ceiling. Each radial strand is a cable, while each cross strand is a harp string of varying length tuned to each note of the musical scale.
A mechanical spider moves about the web plucking it's pre-programmed melodies with four legs as the other four change it's position on the web.

       The strings could be made (of) light [link].   

       Sounds like the intention (in tension?) is to place cables from floor to ceiling, then have the harp "strings" strung horizontally between cables. The tension at the apex could be managed by a (steel and concrete) dome structure that would be in compression, and therefore quite strong. +
