Mix and resultant metallic properties must be researched and available.
It should not be that difficult to relate that to changes in resonant
frequencies and the Q factor of the various resonances.
To much tin causes a brittle mix.

It would be interesting to have an idea how much variance is available
before tone or brittleness become are compromised.




Most definitely: a higher the copper content produces a much softer 
bell metal and a much duller toned bell.

One of the interesting comments in Trevor Jenning's history of Taylors is
that bell metal, when at the right balance of metals and temperature, has a
certain boiling pattern, rather like jam when it's ready to pour.
