[Mr. Mac's]

Ron,

With one of your descriptions I was struck this morning with an example
  of a way for me to remember whether to add or subtract mass
     to change the pitch of an object.

Handbells: more mass, lower pitch; less mass, higher pitch.

Trusting this is a valid deduction.

Sincerely,

Keith
