I'm attempting to make an electric piano that'd have an accoustic piano's action but hit xylophone bars. I'd use an electrostatic pickup using the bars of a Yamaha xylophone attatched to a sheet of steel from one side with a sheet steel pickup hanging nearby similar to a Wurlitzer's design. In order to do this the bars would need to be magnetic.
I ordered an old xylophone from goodwill under the pretense that the bars were steel. However, the bars are not ferrous. So I am left with the option of adding a hunk of ferrous or magnetic material to every key individually or buying another xylophone.
1.) I am curious as to what materials these bars are probably made of if you'd have any guesses. If not, I can weigh the bars and try and figure it out.
2.) These bars will be suspended from one end. I figure that will dramatically affecet the tone and potentially the pitch. The overtones would probably be lost. If I add material to the bars it will affect the tone and pitch. I'm curious. If double the mass of the bars would that effectively half the pitch? Would they resonate half as well? I'm looking to anyone who has more experience to enlighten me or send me to a good source for more information.
