Today I tested the initial concept and it failed. The tubes can't be supported on cross bars it kill sound. I revised the concept. The copper tubes will be suspended by strings inside a frame as shown here.

Not visible on this drawing, there is a string at the bottom too otherwise the pipes would swing when hammered.
