H'mm, I remember this when I was first learning to tune aurally. My wife's grand backed up to a window. I could see strings sharpen up together. I can still see wound strings come into phase by just watching them. The little ones are harder for my eyes. And I do use an ETD but don't spend any time watching it when putting unisons together so I get to see this every time I tune a piano in a well-lit environment, not too often in south Texas where dark is associated with -cool-. :-) Andrew Anderson At 09:55 PM 9/19/2007, you wrote: >I for one found it very interesting.
