Soundboards

[Richard Moody]

Don't forget the string has mass.  Look at the primary formula, mass,
length, tension.  Of course the longer string, the more sound board
needed.  Actually the more sound board available. The energy
available is a function of the mass excited, (activated) ( set in
motion)
