The "point" is that it also takes time to move the little rubber mutes. Maybe just seconds, but you have to do it for every single string, so it adds up. Once the strip is is, a quick pull and you are on to the next string in the unison Also, I think its a whole lot easier to check for correct octave stretch and progression of thirds/sixths when you have the whole piano to listen to at once as opposed to a just a few notes you happen to be tuning. Having said that, I go back and forth between methods. [k]urt <div> </div>
