>In summary, can we assume from your comments that: > >1) DUPLEX adds "colour" to the tone of any piano ? *Noise, character, 'tension', soul. Yep, that's it. >2) DUPLEX "tuning" is mostly garbage ? *Theory aside, in the real world, yes. You've read Del's post by now. >3) Except for the adjustment of downbearing, Duplex "wedges" serve no >significant purpose? *Not so. They do add to the total sound, especially in the problematic areas of the scale inherent in traditional soundboard design - like the 'killer' octave. >4) It is/maybe desirable to "mute" the duplex strings during tuning ? *It depends on the piano. I tend to feel that a tuner should listen to the piano 'as it's going to sound' (I.E. neat) as he/she tunes it. Consequently, I mute duplexes during tuning only when I can't deal with the noise any other way. Ron
